Relevant experts believe that solar cells would also like to maintain its high growth rate. United Nations Energy Agency said that renewable energy development of silicon solar cells, will be 20% to 30% of the rate of 50, because of the depletion of traditional energy sources.

     China's industrial polysilicon starting in the 1950s, 60 in the mid-20th century to achieve the industrialization of the 20th century to the 1970s,battery manufacturers have developed to more than 20. However, due to backward technology, serious pollution, consumption, higher cost reasons, most enterprises have been cut-off due to losses or approach to changing products.

     So far, domestic production of polycrystalline silicon in Silicon only high-tech Co., Ltd. in Luoyang, Emei Semiconductor Materials Plant (by), Sichuan Xinguang Silicon Technology Co., Ltd., Xuzhou in Jiangsu Photovoltaic Technology Development Co., Ltd. to 4 Enterprises.
