The reporter learned from the Fujian Provincial Department of Science and Technology on February 17 that Quanzhou Nanan Sanjing Silicon Refined Co., Ltd. independently developed the first large-diameter solar-grade silicon monocrystalline rod in Fujian Province. The localization of high-purity crystal silicon purification technology has broken the monopoly in this area by a few developed countries.
According to reports, the physical purification technology for solar-grade high-purity silicon successfully developed by Tri-crystal Silicon Refinement Co., Ltd. has the features of simple process, large output, low energy consumption, and no pollution. After the production of photovoltaic battery products is fully operational in July this year, the annual output of monocrystalline silicon (polysilicon) is expected to reach 200 tons, and the annual output of photovoltaic cells is 25 megawatts. Under the guidance of the photovoltaic high-purity silicon project, the company will form a complete domestic solar silicon material, battery and application industrial chain with a total output value of up to 1.2 billion yuan.
According to Wen Lishi, academician of the Chinese Academy of Engineering and a researcher at the Institute of Metal Research of the Chinese Academy of Sciences, high-purity silicon is the main raw material for photovoltaic products. Having mastered the silicon raw material purification technology, it is equivalent to mastering the lifeline of the optoelectronics industry. The solar-grade high-purity silicon materials independently researched and developed by Nanan Sanjing Silicon Products Co., Ltd. have basically met the needs of solar cell production. Compared with the current purification technology of Western European countries and other domestic manufacturers, this physical purification method has low cost, large output, low price, and no pollution. It has broken the foreign technology blockade and product restrictions on China's solar high-purity silicon production and changed The development of China's photovoltaic industry is hampered by the human situation. Its raw material supply advantage has become a major advantage for the development of the photovoltaic industry in Quanzhou.
Nanan Sanjing Silicon Refining Co., Ltd. is one of the few companies in China that has silicon material purification technology. In 2007, the company's solar grade high-purity silicon material production reached more than 1,000 tons, in 2008 is expected to reach 5,000 tons, in 2009 is expected to reach annual growth of 10,000 tons or more, can supply 100MW, 500MW and 1000MW photovoltaic cells, respectively, is expected to become Nanan photovoltaic industry's largest supplier of silicon raw materials.
