【正文】 太陽電池是利用材料的光生伏打效應(yīng)直接將太陽能變成電能的半導(dǎo)體器件，也稱光伏電池。s villages, 7 1 million, 3,000 million people without electricity. These are the distribution of the population without electricity in western China and a number of islands, some of which are villages without electricity using diesel generators for power generation, power supply 23 hours per day。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 800 townships without electricity power problems in 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。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 time in the United States was born in 1959 into the space solar cell applications, the energy crisis in 1973 after the application step by step to the ground. Photovoltaic power generation is divided into independent grid photovoltaic systems and photovoltaic systems. Independent PV power station, including the villages in remote areas the power supply system, solar household power system, munications, signal power, cathodic protection, such as solar street lamps withbatteries can run independently of the photovoltaic power generation system. Grid PV system is connected with the power grid to feed electricity grid PV power system. Currently technically achievable grid PV power system in the way: housing fixedgrid system and power plan
