Chinese solar cells three to five years will popularize Chinese families

Solar power is clean, green energy, China is also the world's largest producer of solar cells, solar cell panel  but the high price but difficult to enter Chinese homes. The main reason is that the production of raw material polysilicon solar cell prices. On the 11th, the reporter in China's largest polysilicon manufacturer - Jiangsu in the silicon industry has learned that the plant has production in September fell to $ 23.8 polysilicon costs, compared to the international market price of around $ 90 with a purpose great price cut. The company vice president Lv Jinbiao said that China in three to five years will be a significant reduction in the price of polysilicon. When solar photovoltaic cells or in Chinese people's homes spread.

Accounted for half of China's polysilicon production in the silicon industry is located in Xuzhou, Jiangsu Province, is currently the world's largest single investment in polysilicon production base. According to Lv Jinbiao, currently the company's monthly production capacity of 1800 tons, production in 2010 is expected to exceed 21,000 tons, will account for the global polysilicon market share of almost a fifth. China has been able to solve all solar companies listed in the U.S. around seventy percent of the demand. The company's production in the next few years will be 120% of the rate of increase.

Earlier Chinese enterprises engaged in the photovoltaic industry has been in a "two out" situation in which raw materials and sale of land are in the overseas markets. June 2009 JZPTD industry five total production capacity of 18,000 tons of polysilicon production line put into operation, making China the largest producer of polysilicon, Georgia. But also the Chinese raw material in the production of solar cell in this area to break the United States, Japan, Germany's long-term technological monopoly.

Lv Jinbiao said: "With the increasingly tight global energy, solar photovoltaic power generation has a very promising future. Currently, the domestic photovoltaic power generation cost of 1.5 yuan over the next three to five years, they will significantly reduce the market supply of polysilicon prices expect manufacturers together with photovoltaic cells photovoltaic power generation will be reduced to less than the cost of conventional electricity.

America developed a new transparent solar cell film

According to the American physicist organizational networks reported recently, the U.S. Department of Energy's Brookhaven National Laboratory and Los Alamos National Laboratory scientists have developed a light can be absorbed and converted into electrical energy a large area of the new transparent film . This film of the semiconductor and the fullerene material , a micro honeycomb structure . Research published in the latest issue of the " Materials Chemistry " magazine , the paper said the technology could be used to develop transparent how to make solar panels can even be made ​​of this material power windows.

    This material is composed of a semiconductor doped carbon fullerene polymer. Under carefully controlled conditions, the material can be self- assembly method consists of a hexagonal structure micron scale expanded to a size of several millimeters of the honeycomb structure covered with micro plane.

    Responsible for the study of the U.S. Brookhaven National Laboratory Center for Nanoscale Materials versatile physical chemist Mircea Cartwright said that although this honeycomb films produced using conventional polymer materials ( such as polystyrene ) similar process , but for the semiconductor and fullerene material and allow it to absorb the light generated charges is the first time .

    According to reports, the reason why the material can also be transparent in appearance only because the polymer chains are closely linked with the edges of the hexagon , and the remaining part of the structure is relatively simple to connect the center point outward thinner . This structure has a connection function , but also has a strong ability to absorb light , but also conducive to conducting current , while other parts are relatively thin and more transparent, and mainly from the light effect.

    Researchers a very unique way to weave this honeycomb film : First comprising a polymer and fullerene was added , including the micro-scale thin layer of small water droplets. These droplets to the polymer solution after the contact will self-assemble into a large array , and when the solvent was completely evaporated , it will form a large area of the hexagon honeycomb plane. Furthermore , the researchers found the formation of polymers and is closely related to the evaporation rate of the solvent , which corresponds to the charge of the final material will determine the transmission speed . The slower the solvent evaporates , the polymer structure more compact , faster the charge transfer .

    "This is a significant cost and effective method of preparing a lot of potential applications from the laboratory to large-scale commercial production being ." Cartwright said.

    By scanning electron microscopy and fluorescence probe confocal scanning microscope of new materials researchers confirmed the homogeneity of the honeycomb structure , and its different parts (edge ​​, center node ) of the optical properties and a charge generating tests carried out .

    Cartwright said: "We work so that people on the optical characteristics of the honeycomb structure of a deeper understanding . Next we plan to apply this material is transparent and rollable flexible solar cell and other equipment manufacturing them , in order to promote this kind of cellular membrane into the practical stage as soon as possible . "

"Dragon" third leg for the first time to dive samples taken back to a cobalt-rich crusts

"Dragon" today (September 3) in the Pacific Northwest Association of China Ocean crusts mining exploration contracts Weihai mountainous district implemented the first 69 dives job, which is the "Dragon", the first pilot applications voyage The third leg of the first dive, samples taken back to a cobalt-rich crusts. Geology, State Oceanic Administration, Dr. Tang Limei that two of the samples for the study of its metallogenic mechanism, as well as with different occurrences of crusts contrast is important.To learn more please visit: http://www.solarpanelcellonline.com/

Tang Limei said that crusts are widely distributed in the Western Pacific, mainly in seamounts, ridges and Taiwan (with a relatively flat, wide top surface of the seabed Heights) slope. About 50,000 Pacific seamounts, which crusts most abundant storage capacity, but after detailed investigation and sampling of seamounts are few.

She said that the diversity of source material crusts, generally considered to be adsorbed metal element manganese mixed colloidal precipitate formed, bacterial activity in this process played an important role. Crusts usually a few millimeters per million annual growth rate of formation, and become a thick crust, may require thousands of years old, is the Earth's most natural process of slow one.

It is understood that crusts contained in cobalt, manganese, nickel and other metals used in alloys that can increase its hardness, strength and corrosion resistance and other special properties. In some industrialized countries, a large number of cobalt is used in the aerospace industry super alloy production. And high in the chemical industry, the cobalt can also be used in the production of photovoltaic cells, solar cell , fuel cells, superconductors, high-level laser system, a catalyst, a strong magnetic and cutting tools and other products.

The dives also obtained a six wrist starfish, four seamount rocks and two sediment samples, photographed corals, sponges, starfish, sea fish and other marine life information.

Field chief scientist Wang Chunsheng introduced through the dive, found that the giant sea benthos low abundance middle of last month, "dragon" probed Wei seamounts, in line with the characteristics of oligotrophic waters; wrist found in this area six starfish benthic organisms such giant, giant creatures have further illustrate the characteristics of wide distribution.

Disordered molecules plastic solar cells can improve the performance of

Scientists found disordered at the molecular level can actually improve polymer properties. Now, researchers at Stanford University have made the surprising discovery of this explanation. This finding is bound to accelerate the low-cost commercial plastic solar cell development.

To develop work with conventional silicon cells under a high efficient soft plastic solar cells, scientists have spent decades time. Currently, research groups have tried to create new plastic material, by enhancing the current solar cell to improve battery performance. Some research groups re flexible plastic polymer design to silicon in an orderly class, but the current has not been increased.

"People used to think that as long as the structure of the polymer more like silicon, their performance will improve." Co-author of the study and Stanford University associate professor of materials science and engineering AlbertoSalleo said, "but we found that the polymer can not form naturally beautiful, orderly crystals, they can only form a small disordered crystals, and these can just solve our technical problems. "

Salleo and colleagues suggest that scientists do not attempt to simulate the rigid structure of silicon, but to learn to understand the nature of the disorder plastics.

High-speed electronic

In the study, Stanford University team will focus on a class called conjugated semiconducting polymers or organic material that has a plastic performance and the ability to absorb light and electrical conductivity.

Semiconducting polymers was discovered 40 years ago, and was long considered to be ultra-thin small solar cells , light-emitting diodes and transistors ideal material. With rooftop solar panels using silicon crystal is different semiconducting polymers lightweight structure and can be used at room temperature, low-cost inkjet printers and other technology for processing. However, it has not been commercialized is a major cause of poor performance. Electron solar cell needs to move quickly in the material, and the semiconductor polymer is a low electron mobility.

X-ray analysis

In order to observe the micro level disordered materials, Stanford University research team at SLAC National Accelerator Laboratory of the samples were characterized by X-ray analysis. Analysis showed that the molecular structure of the semiconductor polymer resembling a distorted fingerprint. Some amorphous polymer that looks like spaghetti, while others are only a few molecules long tiny crystals.

By analyzing the current through the sample and the emission situation, the team concluded that numerous small crystals dispersed throughout the material by a long polymer chains connected together like beads on a necklace the same. The crystal size is crucial to improve the performance of the material.

The small size of the charged electron crystal can quickly move to the next crystal, so long polymer chains can be carried through the material quickly Electronics. This explains why they are bigger than the size of the crystal is not connected to the high charge mobility.

Another major disadvantage of the crystalline polymer is that it can result in non-soluble by an ink jet printer or other processing technology to produce low cost.

Therefore, they finally concluded that, to improve the battery performance without the formation of large crystals of the steel material, but the need to design small size unordered be closely linked to the polymer chain crystalline material.

Related industry, this wave of rush orders not retreat, indeed favorable inventory to price stabilized phenomenon.

In November, the three countries of / USA / Europe trade war intensified, Nov. 1, the the mainland China Ministry of Commerce decided to conduct anti-dumping and countervailing investigation on the origin of the solar grade polysilicon EU, originally for the United States, South Korea and other countries the investigation of the products also will be merged; November 5, the U.S. International Trade Commission immediately also Chinese solar dual case make a final green light to finalize the switch to a single benefit to Taiwan is expected to begin the implementation.

Individual manufacturers, Motech October consolidated revenue 988 million yuan, a monthly decline of 4.03%. Motech said that since October, orders full load, order scheduling reached in December, the fourth quarter performance will be better than the third quarter of the next year are not particularly pessimistic.

Yu Jing October revenue of 820 million yuan, the monthly growth of 10.6%. Yu Jing, enhance the needs of major markets before the end of the solar system, is expected to have a significant shipment kinetic energy. Including solar PV market demand in East Asia continued, as well as Europe and China has also begun to demand warm.

Sun Branch October revenues of 380 million yuan, the monthly growth of 24%, after dropping for three consecutive months revenue, operating temperature trough the back. Sun Division, said the recent breakthrough in the Japanese module orders, due to the Japanese market for high quality requirements, the relatively better performance on price, so driven by revenue growth in October, the company also intends to amplification Module capacity.

New Sun October revenue 777 million yuan, the monthly growth of 1.68%; Taiji revenue of 186 million yuan in October, the month declined by 14%; DelSolar consolidated revenue of 237 million yuan in October, the month declined by 31%.

Party and 18 report clearly more conducive to the development of the real economy to implement policies and measures to strengthen the demand-oriented, and promote the healthy development of strategic emerging industries, advanced manufacturing. Favorable policies in the photovoltaic industry dropped to its lowest this winter has brought bursts of warmth, the enterprise out of the woods in a confused hope. Businesses see a firm confidence in the national development of this emerging industry confidence substantive open market for the domestic photovoltaic applications.

Prior to the introduction of the relevant planning policies, clear the route and direction of development of industrial technology, depict PV grid parity prospects and goals, has been passing out a signal of support for industrial development. Along with the industry situation is worsening, the state even more clearly for the photovoltaic industry to encourage policies. On September 12, the National Energy Board issued a solar power development "12th Five-Year Plan", proposed in 2015, the solar power installed capacity reached 21GW, photovoltaic distributed generation occupy 10GW. Two days later, the National Energy Board issued reporting large-scale applications of distributed photovoltaic power generation demonstration area, encourage distributed generation project reporting. October 26, the State Grid Corporation released to the community "opinions" on doing distributed photovoltaic power generation and network services work, a significant reduction in the threshold of photovoltaic power generation network, the network voltage less than or equal to 10 kV, the installed capacity of no more than 6 trillion watt photovoltaic power plants, all can apply for access to a large grid, free access services provided by the State Grid Corporation of the whole process.

Countries to encourage the timely introduction of the policy, the State Grid Corporation of effective co-ordination of services, accepted none other on the network, transformation costs are so impressed PV companies, more important is the development of distributed photovoltaic power inverter generation industry development path further clear.

Shrinking global market demand brought capacity relative surplus into the plight of the photovoltaic industry, open the The domestic application market is regarded as an important way to break this impasse. A long time, "grid difficult" is considered one of the bottlenecks restricting the application market will be fully open. The recent series of favorable policies, while clearly the development of distributed generation, trying to break through the grid bottlenecks, to mobilize the enthusiasm of the investment subject.

The new changes allow enterprises may see the future of photovoltaic products to the daily consumption. Photovoltaic products are closely related with people, the overall market environment will be big, like the photovoltaic industry will usher in the real prosperity. As PV manufacturer Yingli Group is confident about the future prospects of the market. They believe that the companies can feel new market space is open, market investment initiative significantly improve. Favorable policies to stimulate many PV manufacturing enterprises have started all over the country looking for a suitable roof actively reporting project.

It is gratifying that, no matter how grim the external environment, the photovoltaic business and did not give up. Photovoltaic manufacturing enterprises and some mining demand in emerging markets with differentiated marketing strategies to meet the needs of different consumers; some in the country to carry out technical cooperation, adhere to the continued research and development of high-efficiency solar cell, reducing the cost of photovoltaic power generation, to accelerate the pace of grid parity ; some transformation and upgrading, development of the downstream photovoltaic power plants business, and enhance profitability. However, whether it is the U.S. "double reverse", the EU's anti-dumping or national policy support, these are external factors, the future of enterprises rely on their own eventually. At present, the domestic photovoltaic enterprises to seize the country to promote the strategic adjustment of economic structure and implementation of important opportunities for innovation-driven development strategy to accelerate the pace of transformation and innovation, the real bigger and stronger.

The high-rise buildings should not be installed solar water heater? Why more cost-effective to buy inverter air conditioner?

Into the winter, a lot of places in the North extensive use of solar panel water heaters, energy-saving and environmentally friendly, Dongguan Why can not more use it?

The air conditioning is essential household appliances, but fixed-frequency air conditioning, inverter air conditioner market, how do we choose?

Two days ago, the Science and Technology Bureau, the Municipal Association and the Municipal Association of refrigeration and air-conditioning in the City Science Museum organized of Dongguan Innovation Forum 2012, invited Guangdong University of Technology, Guangzhou University, Zhongkai College of Agricultural Engineering, Dongguan University of Technology experts and professors focus "Dongguan low carbon economy, refrigeration and air conditioning the development of new technologies. "

Experts said, less use of solar water heaters in Dongguan, is because high floors households, while the roof area is small and can not meet the needs of all users.

Although the inverter air conditioner than fixed-frequency air conditioning 1000-2000 yuan more expensive, but the energy-saving rate can recycle up to 50%, 3-5 years, this "extra" costs.

9 floors building solar water heaters should be installed

Four energy-saving industry in the industrial, construction, transportation, and living in the building energy efficiency is regarded as the highest areas of the "heat".

Civil Engineering Associate Dean of the School of Guangzhou University, said Professor Ding Yunfei, building energy efficiency to reduce environmental pollution, one of the most direct measures to improve the quality of the urban environment.

Previously, received attention for building energy efficiency is not so high industrial energy efficiency.

Ding Yunfei, a lot of people on building energy efficiency do not understand simple point that is to improve the energy efficiency of the building, the rational use of energy. Including heating, air conditioning, hot water supply, cooking, lighting, household appliances and other energy consumption. " , in the developed areas in Guangdong, the national requirements Guangdong energy saving of 18% in the next five years.

It can be foreseen that the field of building energy efficiency will be the market of Dongguan enterprises "mettle".

At present, the province has developed a lot of building energy-saving measures, such as unified install  solar cell  water heaters require new residential.

"However, this is conditional installed 9 layers would be more appropriate. Imagine, the installation of 30 multi-storey building, on the top floor so the slightest position, where collectors do?" Said Ding Yunfei, too high-rise buildings to install, set The hot area is not enough, the water supply can not meet the needs of all users, it is not feasible.

Than the fixed-frequency air conditioning inverter air conditioner energy by 50%

Another piece of building energy-saving potential of land, in the air conditioning energy.

Now available in fixed-frequency air conditioning, inverter air conditioner, many varieties, there are also significant differences in price.

Brand fixed-frequency air 1800 yuan can buy, the inverter air conditioner 4000 yuan price.

The public should be how to choose?

Ding Yunfei said, the traditional fixed-frequency air using the compressor kept open, stop "to adjust the indoor temperature between open open the stop will consume a lot of power.

Inverter air conditioner inverter control technology to regulate the compressor speed according to the ambient temperature, room temperature fluctuation is small, less power consumption.

"Although the inverter air conditioner than fixed-frequency air conditioning your 1000-2000 energy saving rate of up to 50%, 3-5 years, you can recycle this" extra "cost." Said Ding Yunfei, Moreover, a 10 air-conditioned life in general -12 years, minus the payback period, the remaining earnings period.

In addition, the recent four ministries, the Ministry of Commerce, the National Energy Board, the Ministry of Finance, Industry and Information Ministry, and 36 representatives of banking institutions in Baoding, Hebei held a secret meeting to begin to discuss the future direction of development of the PV industry in China.

The analysis said that the photovoltaic industry will welcome the opportunity for development. Related listed companies has Tianwei change, New extension Tebian the electrician, Jiangsu Sunshine, sunflowers, Dongfangtanye.

is n � e o �-g ��f
In response to this situation, Miao Sheng Jiang suggested that the government promote the installation of solar must for local farmers to strengthen publicity and education and awareness-raising.

In addition, the reporter online access around the country to promote solar pest control lights experience found that many domestic  solar cell   pest lamps included in the agricultural subsidy program to encourage farmers to actively use. Doumen District of Zhuhai City, Ji'an City, Jiangxi Province, Xianyang City, Shaanxi Province.

Haier solar boost national returning farmland to forest project implementation of the landing

Buy a new solar very friendly, clean, health and save money, more important is to still can enjoy the government to let’s subsidies. “Recently, live in gansu tianshui of returning farmland to forest WeiDaShu farmers with the government subsidies to buy the haier solar panel happily from ear to ear after. Of course, can get subsidies is that he is not just a person, but is all returning farmland to forest farmers. It is reported, to consolidate returning farmland to forest project results, the national special established consolidate the achievements of returning farmland to forest special funds, farmers according to local regulations when buy solar energy can be obtained corresponding subsidy funds.

According to introducing, to ensure that the returning farmland to forest farmers can buy quality guaranteed solar water heater, local authorities in the review and select suppliers with a most strict rules, not only the requirements of the solar energy product quality is guaranteed, and the brand, after requirements for more demanding. Selected, haier solar stand out. “Was chosen to haier solar energy, not only because the product quality stands up to the most rigorous test, can satisfy the use of farmers demand, but also because it can resist rural sandstorm big, winter cold rough weather.” Local a government staff, told reporters that due to the returning farmland to forest farmers in the geographical position an adverse environment, and haier solar stent with the use of high quality galvanized steel plate, the load bearing ability is strong, can fight the gale, can adapt to this kind of bad environment, and quality guaranteed. Therefore, they choose the haier solar energy.

The reporter understands, in addition to the safety performance, haier solar heat preservation performance better, because of its using the original horizontal type foaming technology, foam layer more uniform density, and combines haier solar pioneering poly hot ring technology, makes the water tank and the connection between the vacuum tube is more close together, to prevent tank heat loss. Even if the wind and rain for five straight days of sunshine, the temperature inside the water tank is still keep in 40 ℃ above. “With this kind of solar energy, the future winter also is not afraid of no hot water.” Just get subsidy funds of returning farmland to forest farmers ms. Li said in a good mood.

For why can be selected, haier solar professionals heart more clearly, “haier solar cell valve adopts the advanced international three target coating, the coating quality stability, adopt heat effect obviously improve. And use USES the food grade stainless steel tank, and more suitable for rural areas of poor water quality situation, has the strong KangFuXing, service life also greatly extend”.

As we have learned, haier solar energy to meet consumer demand in rural areas, on the basis of the city also actively explore the market demand, developed for the city high-rise building use flat solar energy water heater, broke the solar energy into the city difficult problem. Haier flat plate solar adopt fission style plate design, not only beautiful and easy, and high strength toughened glass make flat collector can bear the weight of 1.2 tons of car, hail, frost resistance, fight sandstorm and extreme weather, even if a temperature of minus 30 ℃ can also use as usual.

Before long has just opened in guangzhou the 112th Canton fair, haier solar energy with its products appear as soon as we have received many foreign welcome and praise. As we have learned, haier solar charge controller after many years’ hard work not only in the market to establish a good reputation, and in the product technology development has made a lot of new breakthroughs, and has won the South Africa, France, South Korea and other countries quality authentication technology.

Yingli change and self-help

Yingli employees, thousands lined up to assemble at Yingli Group Headquarters Plaza, Liansheng Miao forever convey on stage with his new strategy, while previous misjudgment of the situation to make the review. "I ignore a problem, is a major error, many countries faces an election this year, the great impact of this on the industry."

Miao, Yingli Group chairman Zhengrong Shi, Gao Jifan, Qu Xiaohua, known as the "four kings" of the Chinese PV industry. The four of them seedlings bold, forthright with that. September 17th, Yingli Group to all staff issued a written proposal to overcome the crisis are all revealed on Miao soldiers atmosphere. "Breakout jump out to blaze a new trail crossed the photovoltaic snow-capped mountains, beautiful spring day in order to meet the photovoltaic industry!"

Like other Chinese PV companies, beleaguered photovoltaic winter and did not let Yingli immune. The group recently published internal publications such period of about: 14 years into the PV, Yingli with other domestic counterparts, has been focused on the rapid expansion, the rapid expansion and competition for market share, but it has accumulated a large number of structural and quality contradiction, resulting in a lack of independent innovation, overcapacity, insecure management infrastructure, a range of issues such as corporate culture diluted, which has seriously hampered the sustainable development of enterprises.

"The current situation in the industry, the companies do not take the initiative to change, full positive transformation and upgrading, there is no way either upgrade or out." Said Liansheng Miao. In fact,solar panel after 10 years of rapid expansion, Yingli has come to a depth adjustment and integration of the mark.

"334" strategy

Has been recognized as the industry the most complete industrial chain PV companies "Yingli, but now find themselves missing one of the most important part - the power station.

Over the years, as the head of the Miao Liansheng corporate strategy has two taboo: neither do the power station, do not get involved in thin film solar. The production of photovoltaic products from Yingli has for 14 years, has never been one dares to deviate.

Liang Tian, ​​Yingli Group Director of Public Relations, explained toreporters: power station previously not our core business, and thin-film technology is relatively immature, the conversion efficiency is low, so these two areas had not been involved. "

This time, in the face of menacing PV Storm has always been stubborn, tough to have a soldier Total temperament Liansheng Miao, finally broke the taboos of their own thinking. In order to cope with the situation of current industry slump, Yingli has developed a strategy of "334".

Liansheng Miao explained that the so-called 334 strategy, future Yingli PV products distributed 30% of terrestrial photovoltaic power plants is characterized by large shipments; 30% of the roof system, take the lightweight road, combined with the roof generation high efficiency; 40% is distributed, stand-alone PV systems, fast back section of low-risk. "

In order to adapt to this strategy, Yingli has begun consciously dispatched a group of its production. Yingli expects to double production by 2014, but this year, Yingli or cut a full year PV module shipments target the original 2.4 to 2.5GW, down to 2.1 to 2.2GW.

Yanada Yingli production, it will take a configure-to-order production capacity, and not only production regardless of the ability to sell. "Seller's market-led model does not exist, so must production cost control, production and sales to achieve a reasonable balance."

To cope with the "334" strategy, marketing model, Yingli ongoing exploration of the "one-stop" mode. This model will be user-centric, that let users from mentioning products, self-install, Yingli offers consulting, maintenance and other full-service.

In contrast, the previous model customers buy of 10MW and even 100MW disposable products, and then sold to downstream installers, and "one-stop" mode is to take residents from mentioning the product Self installed.

Currently, Yingli built in Spain, the first demonstration of a center, and their various components, cables, inverters and so put in there, as long as the local residents to "take" to go, you can go home installation. In fact, this is a very slow process of cultivating. After the Spanish pilot, will layout in the world. Yingli has worked out a lot of sales model, such as their co-operation and local banks,solar cell to do a complete set of the financing system model generation yield model. These modes are good copy. Beginning in September, Yingli has such a "one-stop" mode extended to Germany, Italy, and Greece. Then after will be extended to Singapore, Singapore radiation the whole of Southeast Asia.

As expected, sales of the product of the future "one-stop" mode will account for 40% of the of Yingli total shipments. The second half of next year, Yingli will have a dozen products into supermarkets in Europe, America and Japan.

Technological revolution

In the photovoltaic field, despite the current crises, but the technology is still a pilot. Although LDK facing huge losses, but they still put the technology research and development as a powerful weapon to resist risks. In the beginning of the year, Zevi launch research and development for nearly a year, the efficient M2 polysilicon films, 0.3% to 0.4%, its higher efficiency than conventional silicon wafers. Currently, they have successfully developed the M3 wafers, the efficiency of the use of solar energy is even higher than M2 silicon 1.5. Zevi, chief technology officer Wan Yue Peng said: "This will be our secret weapon in the future market competition."

Like LDK, Yingli also has its own secret weapon. Yingli Technology Innovation Expo on September 25, in addition to the Panda N-type monocrystalline silicon efficient solar cells and large-capacity magnetic levitation flywheel energy storage products, the Tibetan antelope project, MWT battery R & D and technological achievements in exhibition full debut.

While the high-capacity magnetic levitation flywheel energy storage projects have become the biggest bright spot. Previously, Liansheng Miao, has revealed in an internal meeting, the entry point of the Yingli will be intelligent communications and smart grid industry as large energy storage projects, the large energy storage projects as soon as possible industrialization. This also means that Yingli flywheel energy storage project strategic layout: smart communications and smart grid.

The so-called flywheel energy storage, is the use of high-speed rotation of the flywheel energy to kinetic energy in the form of storage. Requires energy, the flywheel is a decelerating operation, the stored energy is released out of advanced physical energy storage mode. The advantage: have high-power, high-capacity, high-efficiency, instant charge, discharge, safe and reliable, green, long life, free from the restrictions of geographical environment advantages. A wide range of services in the smart grid, communications, distributed power generation and other new energy generation system.

Currently, domestic flywheel energy storage research behind about 10 years of foreign intervention by U.S. venture capital, flywheel energy storage device has to do every day consuming only 2% of the energy storage. Yingli flywheel energy storage device technology content Liansheng Miao said, than Europe and the United States, all production equipment is custom, not to buy imported equipment.

Analysts pointed out that to make up for intermittent renewable energy generation and instability defects grid renewable electricity smooth, high-capacity storage technology will be the key to solve new energy power generation and network bottlenecks where. The same time,solar charge controller the domestic "Twelve Five" period, and building an independent, market volume of distributed photovoltaic power generation system will also provide large-capacity storage to create a huge market demand.

Crystalline silicon solar cell laser edge insulation treatment

With the steady development of the crystalline silicon solar cell industry, the laser has been considered as an important tool to improve the quality of the battery and reduce manufacturing costs. Laser machining such as laser ablation electrode (LFC), the laser groove buried gate electrode (LGBC), as well as applications such as M / EWT growth significant application in the manufacture of crystalline silicon solar cell, the most widely used one of the laser process is a laser edge insulated.

c-Si in the battery manufacturing process of the N-type ion doping / diffusion into the P-type silicon substrate forming a micron level N-type doped layer, this layer surrounded the entire wafer, resulting in the front and back electrodes of the battery shunt insulation processing must be on the edge of the battery in order to avoid shunt.

Crystalline silicon solar cell laser edge insulation treatment

The typical laser edge insulation processing is performed by scribing trench in as close as possible around the outer edge of the solar cell to achieve. In order to obtain the best insulating effect, the depth of the trench must be greater than the ion diffusion layer, the typical trench depth is 10-20um, a width of 20-40um. Spectra-Physics laser products have many models capable insulated, but processing the fastest, highest quality or the latest Q-switched solid-state laser series, which preferred Pulseo 355-20.
355nm short wavelength, short pulse width of 23ns makes Pulseo laser ideal is insulated from the solar panel process. Insulation dicing speed laboratory tests prove that combine high-speed scanning galvanometer, Pulseo 355-20 in 1-2 seconds can be insulated 156mm wafer the integrated processing equipment depends a good optical system design (spot) hope to reach 500-1000mm/sec or higher.

Because of the short pulse width, the role of the silicon wafer caused by 355nm short wavelength shallow depth factors created precision insulating Pulseo ultraviolet laser scribing. As another option 532nm laser can also be used for insulation crossed, and maintain the same high speed and high quality.

For green light, we provide Pulseo 532-34, a high-power Q-switched lasers. When combined with the current scanners, access to both high-speed cornering with minimal ablation. 120kHz repetition frequency under extremely high power and stability, and superior performance to it under a small focused spot can be obtained a smooth uniform scribe line. In short, the short pulse width of Pulseo 532-34 combined with high peak power and high repetition rate to bring clean and efficient laser insulation crossed effect.

Crystalline silicon solar cell laser edge insulation treatment

The edge of the solar cell insulation treatment recommended products a: Pulseo laser

The Pulseo series laser continuation of the excellent quality of the all-solid-state Q-switched laser Spectra-Physics high-power, high-repetition-frequency, high peak power, short pulse width, with strict manufacturing standards, ideal for high precision machining for industrial applications.

(F) on the positive and cautious relationship problems.

A positive attitude and a fearless will to get anything done on the basis of the entrepreneurial spirit is very valuable. Our urgent need to seize a rare historical opportunity, as soon as possible to achieve a breakthrough in this new high ground of the new energy. New energy industry chain length, the obvious effect of stimulating the economy and increasing employment. So, the local governments and enterprises to develop new energy attitude is very positive, which made many recommendations to accelerate development, such as: Do not argue, do not be afraid of chaos, to dry up first, to solve the problems in the development process in the development of its urgent The feelings are understandable.

However, the development of an industry’s eagerness and desire to this industry can bring an important contribution to the economy and a large number of additional jobs, and not a substitute for all sectors of the industry, “technically feasible and economically reasonable” basic requirements. Each and every element have the technical feasibility and economic reasonableness is normal functioning and healthy development of the industry chain really protect. The scale of investment in new energy industry is huge, huge total occupied various social resources, including a large number of government subsidies to fund a wide range of impact, the power is still very expensive. Only in this industry all facilities to achieve normal operation according to the design level, in order to receive a look forward to the effect of stimulating the economy and increase employment. Otherwise,solar charge controller they cause a greater loss of the whole industry chain.
China’s economy and society can not withstand the “toss”. The development and utilization of new energy sources have both positive and enterprising spirit, but also “in perpetuity”, “standing on the edge into the abyss” as a sense of responsibility. Both spirit reflected in the research questions seriously, respect for scientific truth, and comply with relevant state laws and regulations and construction procedures, specifications, preparation and demonstration project feasibility study report, the practical implementation of all aspects of supporting conditions, attaches great importance to the country for the construction project “technically feasible and economically reasonable” basic requirements, commitment to reform, the timely removal of institutional obstacles, establish and improve the public, fair, fair competition and comparison mechanism, to learn the lessons of the various aspects of middle age, in the specious argument, cooling Great Leap Forward “of the impulse to avoid the loss of” haste makes waste “, as possible” rainy day rather than the KMT, calmly, steadily and surely, worked out in line with the laws of science, certain forward-looking policies, realize effective in promoting the healthy and sustainable development of the new energy industry.
