Our analysis and improvement of solar cells attached excellent significance, as early as throughout the Seventh Five, amorphous silicon semiconductor research function has been integrated in key national troubles Eighth and Ninth 5-Year period, China’s focus on the investigation and improvement of large region solar cells and so on. October 2003, the National Development and Reform Commission, Ministry of Science to create solar power sources in the subsequent five years development program, the NDRC “Vibrant Project” will raise 10. billion to market solar power technology, the 2015 National Solar Energy total method capacity of 300 MW.
In 2002, the state ministries launched the “Western Provinces Rural without having electricity energy scheme”, by solar china and little wind energy to resolve seven provinces in the western town without having electricity polysilicon solar cells
Electrical energy. The commence of this project significantly stimulate the solar energy industry, China has built numerous solar cell packaging line, so that the production of solar cells is increasing swiftly. China presently has ten solar cell production lines with annual production capacity of about 4.5MW, of which eight production lines introduced from abroad, in which the 8 production lines, with six monocrystalline silicon solar cell production lines, 2 Si solar cell production line. Experts predict that China’s PV marketplace demand for the present year 5MW, 2001 ~ 2010, the annual demand will reach 10MW, beginning in 2011, China’s PV market place demand will far more than 20MW.
At present, solar silicon production enterprises are mainly monocrystalline silicon factory in Luoyang, Hebei, Sichuan Emei ningjin silicon base and factory and other producers of semiconductor components, including silicon base ningjin Hebei is the world’s largest solar silicon production base, accounting for Globe solar silicon market place share around 25%.
Downstream marketplace in solar cell materials, the present domestic production of solar cells are Anwell Group organizations, Suntech, Nanjing Energy, Baoding Yingli, Hebei JA, Solarfun Energy, Suzhou Artes, Changzhou Trina, extension Nisshin energy, Yunnan days of Photovoltaic Technology, Ningbo Solar, Kyocera (Tianjin) Solar Energy and other firms, for a total annual capacity more than 800MW.
In 2009, the State Council to offer reports that workers think polysilicon excess capacity, the actual individuals are not recognized by the market, the ministry has indicated that no excess production capacity of polysilicon. At present, the application of solar cells from the military and aerospace fields, into the industrial, commercial , agriculture, telecommunications, home appliances and utilities sectors, in certain, can be dispersed in remote locations, mountains, deserts, islands and rural use, to save cost of expensive transmission lines. But at this stage, it is also extremely higher price of issuing 1kW energy need to invest thousands of dollars, so a huge-scale use is still topic to economic constraints.
But in the extended run, as the solar cell manufacturing technology and the new light – the invention of energy conversion devices, national protection of the environment and the massive demand for renewable and clean power, solar cells will continue to evaluate the use of solar radiation sensible approaches for huge-scale use of solar energy the future of mankind to open up broad prospects.
