Suntech person 17 to the second China International Solar Photovoltaic Industry Forum, said amorphous silicon society during solar cell module production approach is more cautious, because compared to crystalline silicon cells, amorphous while on the surface of the silicon cell component costs are lower, but the total cost of the production system, its benefits are not obvious.

This is undoubtedly be launched through the thin amorphous silicon array of stacks of film made a pot of cold water. Recently, amorphous silicon cells (mainly thin-film batteries) components are many manufacturers of solar cells in pursuit of China, there are many places introduces thin film battery program of industrialization.
In response, Beijing New Energy and Renewable Energy Association, Solar Wang Changgui Steering Committee, said thin film battery technology, the prospects are good, but it is still not mature enough because of technical problems, life and efficiency low conversion, the large-scale industrialization must be cautious.

The technology of amorphous silicon thin film so popular these days
Published in 2010 in terms of current draft regional plan, the thin amorphous silicon drum line film is considered one of the key construction projects in many areas.
If Licheng District, Quanzhou, Fujian Province this year, 23 construction projects focus on the implementation of an explicit reference to energy-Jun Shi If the solar cell thin film production line. High-Tech Economic Development Zone, Rizhao in Shandong Province Economic and Industrial Park, which is the production of 12 key projects, including thin amorphous silicon solar cell project.
Thin-film batteries are not due to bottlenecks in supply of raw materials in the production process is short, the advantages of low cost benefits of it showed, with the last two years, the cost of cells crystalline silicon high, the market began to appear to promote the balance of the end of thin-film batteries. On capital markets, the concept of thin amorphous silicon batteries once the acclaimed film. PB991A PB992A PB994A
New extension to notice a few days ago, said the company has developed in the emission of no more than 3850 shares, to raise funds not exceeding $ 81,000 for a wholly owned subsidiary of Rio building is located in Shaanxi Weinan City, Shaanxi Province 150MW amorphous silicon photovoltaic production line cells. Tianwei change security cell layer thin 2 Project (150MW) has already started construction of the project total investment of 3.1 billion euros.
Premature Industrialization
NDRC Energy Institute, photovoltaic expert If Wang Cheng said that on the technical maturity of the cells of amorphous silicon compared to crystalline silicon cells are not a small gap, while the conversion efficiency and life services, and crystalline silicon cells are not. Although amorphous silicon cells, the greatest advantage of cost of production is also facing challenges. PB995A PP2182D PP2182L
Although amorphous silicon cells because of lower costs of raw materials, but with the cost of treatment in phase with the production equipment, transportation, system cost compared to crystalline silicon cells has not an obvious advantage. It is understood that the production of amorphous silicon thin components of the battery equipment movie production of photovoltaic modules in crystalline silicon and equipment costs are higher than four or five times, amorphous silicon thin film conversion solar cell efficiency of about 10% on average compared to crystalline silicon cells Tablets 17% -20% there is a certain distance.
It is understood that the current world consists of solar cells, crystalline silicon cells are an important part of the production of components, the technology is more mature. 2009 statistics show that worldwide, the components of crystalline silicon cells in more than 70% of the total, while the thin film battery components accounted for only about 18%.

Wang Changgui said thin film battery is indeed a promising future technology, but at least the most recent period is difficult to compete with crystalline silicon cells. At the end of 2009, production of China represented a variety of thin-film batteries not exceeding 10%. He predicted that by 2030, this proportion should increase to 30%, but the remaining 70% must crystalline silicon cells in support.
He said that the ongoing efforts to strengthen research and development of technology for amorphous silicon cell is a major trend, but now voted to construct amorphous silicon large-scale components of the battery production line thin film, or there is some risk, after all, the reliability of the technology and long term stability Sexual not yet been fully resolved.
