China's Thin

Since 2003, crystalline silicon solar cells the main raw material polysilicon prices have risen 10 times, from the original 20 U.S

. dollars / kg soaring to nearly 300 U.S. dollars / kg. In the raw materials, a "rise in the price", it naturally turning to the industry's raw material consumption of silicon and crystalline silicon solar cells is only 1% of the amorphous silicon thin-film solar cells. Like all new industries, China's thin-film solar cell industry will face in the development process, "Growing Pains" and must get past a number of difficulties.

Photoelectric conversion efficiency to be increased. Compared with the crystalline silicon solar cells, despite the thin-film solar cells have no doubt that the cost advantage, but its 5% -8% of the photoelectric conversion efficiency of crystalline silicon solar cells less than 1 / 2, through technological breakthroughs in order to enhance the photoelectric conversion thin-film cell efficiency is a major issue. Of course, the size of thin-film solar cell production conditions are ripe for research and development work can be established on the basis of industrialization, which advances in technology will undoubtedly be helpful.

Manufacturing equipment controlled by foreign companies. In recent years, the domestic in the crystalline silicon solar cell manufacturing equipment, the field of rapid development, but the thin-film solar cell equipment market continues to be the United States Applied Materials, ULVAC, Japan and Switzerland, Oerlikon carved up by three companies. Thin-film solar cell industry, China should also be concerned about the development of equipment manufacturing industry.

The high price of the entire PV industry needs to face. At present solar thermal electricity price is 10 times. Some experts pointed out that with the increase in costs of environmental protection, thermal electricity price change will show a rising curve, while the thin-film solar cells with the electricity price will be a large-scale production and conversion efficiency gradually decreased, the two curves is expected to in the intersection between the years 2012 -2015.

Market prospects are also not to be ignored. Crystalline silicon solar cell industry in China is characterized by a "two out", that is the main raw material producing areas and the major markets abroad. Even if the thin-film solar cell industry to alleviate problems of raw materials, it can not avoid the risk of excessive dependence on international markets.
