【正文】 , but supporting a special materials and equipment also can not keep up, in which the solargrade polysilicon material particularly conspicuous. Countries should be anized photovoltaic industry with chemical, mechanical and electrical equipment manufacturing industries joint research, at the same time actively seeking international cooperation in solargrade silicon as the breakthrough point, to avoid the technology of semiconductorgrade silicon blockade. 39。s photovoltaic industry, the size and technological level of industry have been raised accordingly. But pared with developed countries, there is still a big gap, such as: the degree of domestic raw materialsspecific is not high, species was inplete, already made materials and ponents, its performance is lower than abroad, such as silver, aluminum paste, EVA, etc. . Packaging ponents suede low iron glass, TPT has not yet been put on the market. The upper reaches of small photovoltaic industry chain, the lower reaches of large imbalances, the most serious is that the production of solar grade polysilicon is blank, entirely dependent on imports. The difference between the part of other aspects of the need to import, 3 such as cells, silicon ingot / silicon, supporting materials. The level of industrial equipment design and manufacturing capabilities behind. Polysilicon casting furnace, wire sawing, breaking pletely the need to import ingot。s total installed capacity of photovoltaic systems reached approximately 65MW. Shenzhen, Shantou, Guangzhou and Zhejiang, solar garden lights, a large number of exports, with annual sales of as much as 500 million. Garden of the cells used are usually imported, and then with plastic packaging, simple process. The 6MW cells by as much as a year is a large solar applications (which are not into statistics). China39。s 800 townships without electricity power problems in China39。s solar cell production capacity increased to / years, the price is also from 75 early 80 yuan / Wp dropped to 40 yuan / Wp around. After the niies, with the shape of China39。s solar market development China started research on solar cells in 1958, in 1971, China successfully launched the first applies to the 2nd satellite Dongfanghong. Started in 1973 for groundbased solar cells. China39。 1 附錄 A 英文文獻(xiàn) world39。s current situation and development of photovoltaic industry forecast Solar cells is the use of the material effects of photovoltaic solar energy into electrical energy directly to the semiconductor devices, also known as photovoltaic cells. In 1954, the first practical silicon solar cells (η = 6%) and the first atomic power station at the same
