laptop Batteries: 51 years of Chinese solar cell development process of national industry B

51 years of Chinese solar cell development process of national industry B

In 1969, the semiconductor silicon solar cell research stopped, and then, Tianjin 18 Oriental Red II, III, IV series geostationary orbit satellite development and production of solar array.

Academician Wang Zhanguo said: "The late 70s, China and the international year study carried out gallium arsenide solar cells, the cell has high light emission and light absorption coefficient, 1999, 2 × 2cm2 cell conversion efficiency of 22%."

1975 Ningbo, Kaifeng has set up solar factory, the battery manufacturing process to imitate the early production space battery technology, the application of solar cells began to descend to the ground from space.

In 1998, China's solar industry has the first "to eat crab" people

80's of last century, China began to enter the embryonic solar cell R & D work in sequence around the start, but progress is slow.

Rong-Qiang Cui said that the State Planning Commission in 1986, rural energy, "Seventh Five-Year Plan, 1986-1990" listed in the "solar cell" feature, there are six universities and six research such as crystalline silicon cells start research.

The late 20th century, 80, has introduced a number of domestic solar cell production line, including Yunnan semiconductor plant from Canada to introduce the 1MW (MW) production line, the Chinese solar cell production capacity from several hundred KW (kilowatts) at once upgraded to 4.5MW, this capacity until 2002, the yield is only about 2MW.

"90 years late for the steady development of China's solar cells, after the introduction, digestion, absorption and re-innovation, solar cell production technologies and processes to ensure a stable development and improvement, steady growth in production, basically meet the domestic market needs and have a very a small amount of export. "Rong-Qiang Cui said.

In 1998, our government started to pay attention solar power, proposed the first set of polysilicon cells and applications 3MW demonstration project, the news that the present Tianwei Yingli New Energy Resources Co., Ltd Miao Lian-sheng, chairman saw a ray of hope. However, when the development prospects of the solar energy industry is not yet clear, exacerbated by policy factors, a lot of people on this new energy projects prohibitive. Partners exit in case of seedlings with students decided contrarian, to secure approval of this project, China's solar industry first "to eat crab" people.

In 2001, Suntech established 10MWp (MW) solar cell production line to be successful, in September 2002, Suntech first 10MW solar cell production line officially put into production after four years is equivalent to the sum of the national production of solar cells, in one fell swoop would be our and shorten the gap between the international photovoltaic industry for 15 years.

December 14, 2005, Wuxi Suntech Power in the New York Stock Exchange, Suntech's turned out and brought extraordinary development of the "richest man in effect" the solar energy industry in China started the accelerator, the domestic production of solar cells and research and development are also into the fast lane.

Tianwei Yingli responsible person, December 19, 2003, the company's projects have been formally confirmed by the state, fully operational, can not fill the commercial production of polycrystalline silicon solar cell blank.
