Development of solar energy in China

Our research and development of solar cells attached great importance, as early as during the Seventh Five, amorphous silicon semiconductor research work has been included in major national issues; Eighth and Ninth Five-Year period, China’s focus on the research and development of large area solar cells and so on. October 2003, the National Development and Reform Commission, Ministry of Science to develop solar energy resources in the next 5 years development plan, the NDRC “Bright Project” will raise 10.0 billion to promote solar power technology, the 2015 National Solar Power total system capacity of 300 MW.

In 2002, the state ministries launched the “Western Provinces Rural without electricity power scheme”, by solar china and small wind power to solve seven provinces in the western town without electricity polysilicon solar cells
Electricity. The start of this project greatly stimulate the solar power industry, China has built several solar cell packaging line, so that the production of solar cells is increasing rapidly. China currently has 10 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 market demand for the current year 5MW, 2001 ~ 2010, the annual demand will reach 10MW, starting in 2011, China’s PV market demand will 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 manufacturers of semiconductor materials, including silicon base ningjin Hebei is the world’s largest solar silicon production base, accounting for World solar silicon market share around 25%.

Downstream market in solar cell materials, the current domestic production of solar cells are Anwell Group companies, Suntech, Nanjing Power, Baoding Yingli, Hebei JA, Solarfun Power, Suzhou Artes, Changzhou Trina, extension Nisshin energy, Yunnan days of Photovoltaic Technology, Ningbo Solar, Kyocera (Tianjin) Solar Energy and other companies, for a total annual capacity more than 800MW.

In 2009, the State Council to provide reports that workers believe polysilicon excess capacity, the actual people are not recognized by the industry, 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 particular, can be dispersed in remote areas, mountains, deserts, islands and rural use, to save cost of expensive transmission lines. But at this stage, it is also very high cost of issuing 1kW power need to invest thousands of dollars, so a large-scale use is still subject to economic constraints.

But in the long run, as the solar cell manufacturing technology and the new light – the invention of power conversion devices, national protection of the environment and the huge demand for renewable and clean energy, solar cells will continue to compare the use of solar radiation practical methods for large-scale use of solar energy the future of mankind to open up broad prospects.
