PV, thin-film crystalline silicon who play a leading role
Crystalline silicon solar power plant in the maturing of the situation, the thin-film solar cells also began to compete in this potentially huge market. The two technologies compete in the behind, is Applied Materials, Inc., international solar companies, solar energy equipment manufacturers compete between.
May 26, using the Applied Materials equipment, ENN Solar Energy Co., winning solar power plant in Inner Mongolia, is used in thin-film batteries. Prior to Dunhuang, Wuxi and other domestic solar power stations all use crystalline silicon solar cells to generate electricity.
"This is China's largest amorphous silicon thin film battery power generation projects." NDRC Energy Research Institute, Li Junfeng, deputy director told the "First Financial Daily." This is the first thin-film battery domestic power projects.
Advantages of thin-film battery Losing?
New Austrian photovoltaic successful projects, energy saving by the China Investment Corporation, the first phase of the project is 10MW, respectively, and 5MW 5MW thin film crystalline silicon cells.
Applied Materials Asia Pacific Channel Director Xiao Jinsong told the newspaper, compared to crystalline silicon cells, thin-film battery is more suitable for solar power applications.
"But I do not deny the advantages of crystalline silicon cells, in fact, have their own advantages and disadvantages of the two cells." Xiao Jinsong, said crystalline silicon cell power generation more efficient, but cost is also high; Although thin-film solar cell power generation efficiency is lower , but the cost is relatively low.
LDK Solar's president agreed to do director Yao Feng Xiao Jinsong point of view. "Some people these two technologies as a competitive technology, in fact not the case." Yao Feng told the newspaper, thin-film battery applications with low light intensity and temperature adaptability of the characteristics of large-scale power plant used in the desert , and a larger temperature difference between land rich in natural resources or areas of power plant construction, in addition to the main glass curtain wall is also thin-film battery; and city roof projects, require high power generation efficiency, it is mainly the use of crystalline silicon cells.
But Xiangcai Securities analyst Houwen Tao believe that with the decline in the price of polysilicon thin-film solar cells in cost and crystalline silicon cells is not much advantage.
Before the financial crisis, polysilicon prices continue to surge, the high cost of polysilicon in response to pressure, LDK and other domestic companies launched a number of thin-film solar cell projects.
2007 global thin film solar cell production reached 400MW, 181MW in 2006 a substantial increase of 120%; 2008, the global thin-film solar cell production reached 892MW, an increase of 123%.
After years of rapid development, thin-film solar cell market began to cool. The first quarter of this year, Oerlikon sales fell to 39 million Swiss francs (about $ 33,988,500), down 24%; in the first quarter order intake is only 800 million Swiss francs (about $ 6,972,000), down 27 %.
Equipment giants compete for Chinese market
Although LDK Solar LDK, Suntech and other domestic companies, as the current round of explosive growth in solar power the biggest beneficiary, but from the perspective of the global industrial chain, Oerlikon, Applied Materials, Inc., United States GTSolar other solar equipment manufacturer is earn more profits.
Applied Materials company told the newspaper, a thin-film battery production equipment needs hundreds of millions of yuan.
Now, the focus of these companies are gradually moved to the Chinese market.
In 2006, Applied Materials, Inc. before entering the photovoltaic market. In order to develop the Chinese market, the company's executive vice president, chief technology officer, Ke-Ping Ma (Mark R. Pinto, Ph.D.) began in January this year, the Permanent Mission of China.
Currently, the company and two Oerlikon to become the world's largest manufacturer of thin-film battery devices.
Applied Materials, Inc. engaged in both crystalline silicon cell manufacturing equipment, but also engaged in manufacturing thin-film battery devices. Ke-Ping Ma told the newspaper: "We are in the crystalline silicon manufacturing equipment, 75% of orders are from China."
In order to better seize the market, Applied Materials, Inc. in Xi'an deliberately set up a research and development center.
Earlier this month, the Shanghai PV conference, Tom Gutierrez, president of the United States GTSolar also told the newspaper, the company accounted for polycrystalline silicon devices (ingot furnace) is 70% domestic share.
In the first quarter of serious decline in the Oerlikon same. Oerlikon CEO Jurg Henz in an interview with reporters that: "China is our first important market, although we are now in Germany, there are some customers in southern Europe, but we are very optimistic about the Chinese market."
Currently, Oerlikon has 12 customers worldwide in the production, of which there are two in mainland China and Taiwan, two, three in Germany, southern Europe has three.
