Polycrystalline silicon thin-film batteries turn Zhaxian under control
Not track changes in the electrical plan.
Six months ago, a sharp drop in prices of polysilicon in. This is because they are not based on raw silicon, and therefore have a cost advantage of thin film battery experience Sheng Sijie - polysilicon from 2008 before the financial crisis in nearly 500 U.S. dollars / kg rapidly fell to 60 U.S. dollars / kg price,laptop battery the polycrystalline silicon cells cost will be significantly reduced. At that time, Zhengrong Shi, chairman of Suntech said thin film batteries will be difficult, and competition in the cells of crystalline silicon, thin-film batteries investment bubble will be broken.
However, six months after the ride thin film cells, solar coaster business seems once again to come to High Point: With price stability in polysilicon, state capacity polysilicon low end, construction Redundant control the early technology thin-film battery is to rise to drive a new cycle of investment and construction boom.
“State control of polysilicon, and certainly opportunities for thin-film batteries, thin production companies film batteries have to do is to improve the conversion rate, creating a larger market.” dell inspiron 8500 battery,dell inspiron 8600 battery Austrian Solar Energy Co ., Ltd. the manufacturing center of the new Hong-Wen Li, general manager of the “China Business,” told reporters.
“After three years the world will be a thin-film batteries.” A manufacturer of thin film batteries, Zhejiang, projections of cases.
Overall warmer
October 23, the new Austrian Duke Energy Group and the United States formally signed an agreement in Hebei Langfang photovoltaic energy cooperation. The core content of the agreement, both sides will establish a joint venture registered in the United States, each holding 50% shares in the common effort to build solar power plants, hp pavilion zd7000 battery,hp pavilion zv5000 battery construction projects integrated photovoltaic (BIPV) and other companies.
“North America is the world’s largest market for solar power, Duke Energy is the nation’s third largest power company operating in the United States, covering 110 million people with a rich marketing resources. The Austrian new components of the solar cell production and installation of an integrated its own characteristics, the future will be the joint development of large power plants around the sun. “Xinao Group Vice President, the new Director General of Austria Hong Cai photovoltaic fall on the “China Business” told reporters.
As some companies manufacturing thin-film cell solar, one of the new Austrian now has a world-class super-large 5.7 square meters of silicon-based thin-assembly film solar production, mass production were made in June this year. He indicated that this cell line thin film solar production capacity of 70 MW, products, sony pcga-bp2t battery,sony pcga-bp2v battery photoelectric conversion rate of 9% in the next 2 ~ 3 years will increase to about 12%.
“And the Duke Energy cooperation, because we are optimistic about the development of photovoltaic industry. The U.S. government after the change of state subsidies for new energy sources will be gradually introduced, and since the U.S. system of power generation, applications of distributed energy was largely the central electric scale solar have much space. “Cai Hong Qiu said.
A new Austrian media said the sales staff to expedite the opening of foreign markets due to PV of orders from abroad in August, after clear signs of warming, while demand for low cost battery thin film on the rise.
An industry analyst, told reporters, thin film battery industry as a whole is now warming, which inaugurates a good development opportunity for two main reasons: First, prices for polysilicon stable at $ 60 US / kg from top to bottom, should not have greater decline, which makes cells of crystalline silicon and thin film cells, there is always the difference between the stack of thin film still has about 20 % of benefit costs and secondly, September 29, the State Council issued “on curbing overcapacity in some sectors of the construction and redundant to guide the healthy development of the industry, ibm thinkpad r60 battery,ibm fru 92p1141 battery a number of opinions “on industries polysilicon law strict regulations, pollution, and capacity constraints in areas such as goal to form a stack of thin layers of good news.
“Thin-film battery developed rapidly in 2007, its overall market share was 12% in 2008 to 15% this year may reach 20%.” Zhejiang Chint Solar, CEO YANGLI you on the “China Business” Report说. According to Yang, currently, Chint investment in solar cells for nearly 20 billion yuan, the production of the first trial of the China 20 megawatts of thin line microcrystalline amorphous film battery production, and conversion rate also reached 9.2%.
According to the report, more than 30 more than the current domestic companies active in the thin film stacks, equipment imported from abroad, nearly 20 of them to introduce the production line capacity of each approximately 40 MW, the average price for imports of 100 million U.S. dollars, including the introduction of the new Austria Applied Materials Inc. of the United States a range of products have increased nearly 14 billion yuan.
“In engineering Golden Sun, the solar roofs, influenced policy, in addition to overseas markets, China’s future is certainly an emerging market.” Applied Materials Solar Energy Corporation CEO Charles Gay on ” China Business reporter, said a few days ago, the United States Applied Materials R & D Center in Xi’an has been completed which includes a line of thin film panel solar generation.
“The sunny future sales of the western region of China solar cell, battery compared to the thin silicon film crystalline cells, its intensity was weak light, the low cost advantages such as weathering better adapted to the Western Region, which rigid thin film batteries will stimulate demand for rapid development of the entire industry. “Charles Gay says.
Risks remain
However, prospects for thin-film batteries is not a smooth sailing.
The report on the current international industrial production of thin-film batteries are essentially three types, namely, silicon-based thin film solar cells, copper indium selenide Gallium thin film solar cells (CIGS), cadmium telluride cells thin film solar (CdTe). Which domestic firms are mainly the first two, the latter technology has been monopolized by the American company First Solar.
“Finally technology, a conversion rate of U.S. First Solar may achieve about 11% is already the highest in the field of cinema, but nevertheless, the conversion rate varies with crystalline silicon cells for more than half . Suntech is currently the cells of crystalline silicon conversion rate reached 19%, the world of crystalline silicon cells the more advanced 22% conversion rate, the thin-film batteries in a short time is difficult to compete with crystalline silicon cells. “Great Wall Securities Analyst Tao Zhou told reporters.
Zhou Tao, due to the development of thin-film batteries recently, a number of large general-purpose production equipment capable of producing the world’s only three, namely the United States, apple a1022 battery,apple a1060 battery Applied Materials (AMAT) , Switzerland Oerlikon (Oerlikon) and ULVAC Japan (ULVAC), such as new equipment is Applied Materials Austrian imported from the United States, while the Chint is imported from Oerlikon. The production equipment is very expensive.
“Thin-line battery production of films through the price of crystalline silicon cells, usually the production line three times, and some equipment, the price is a unique equipment for manufacturing crystalline silicon cells 10 times the initial investment too risky. And technology thin-film battery, quick updates, equipment, removal rates in the market thin film battery is not widely accepted until the money is difficult to Zhenghui Lai . Lvjin Biao, said deputy general manager of Jiangsu can.
I understand that the crystalline silicon cell equipment manufacturing due to low cost, mature technology, industry 80% of equipment procurement servants, while the thin film battery production equipment, there are still many technologies basic facilities such as PECVD (plasma enhanced chemical vapor) deposition equipment such as the basic technology remains the import, becoming thin film batteries to hinder the development of domestic factors.
However, YANGLI You still believe that plagued the development of thin-film batteries of these factors will be resolved shortly. “The demand is to stimulate technological upgrading of the main driving force, and now the demand for thin-film batteries is insufficient supply, Chint in Ningxia are building a 100-megawatt photovoltaic power stations, acer aspire 5520 battery we expect thin film batteries account for 50%, why is not 100%? Yes because we can not maintain production. ”
In YANGLI You look, the future development of thin film batteries depends mainly on three points: First, the production of technological progress and, secondly, the formation of the industrial chain and the third prize of equipment to low. If these three points can be obtained, the cost of thin film cells is also down 50% in space. “In 2008, manufacturers of thin film batteries solar energy companies First Solar ranked second highest in the world is the only one to make the top ten films of the seller, which gives us unlimited confidence. Three years later the photovoltaic industry is Who is the world says no. YANGLI You said thin film batteries in the spring just arrived.
