随着矿石资源趋向枯竭以及由于二氧化碳排放而引起地球温度变暖的资源/环境问题,作为清洁能源的太阳电池正期待一个大发展时期。自2000年以来,世界太阳电池的生产量正以每年140～150%的速度猛增,预计2010年仅日系厂商即可达3700MW。材料供应不足迄今为止太阳电池使用材料大多为硅,硅又分为单晶硅、多晶硅和非晶硅3类。最近还有使用Cu、In、Ga、Se等所谓CIGS系,CdTe太阳电池,薄膜电太阳电池等上市,它们提高了变换效率,降低了成本,受到人们注目。现生产太阳电池的原料90%使用多晶硅,
As the depletion of ore resources and the resource / environment problems that cause global warming due to carbon dioxide emissions, solar cells as clean energy are looking forward to a period of great development. Since 2000, the world’s solar cell production is 140-150% annual growth rate soared, is expected in 2010 only Japanese manufacturers up to 3700MW. Too short supply of materials Solar cell materials used to date mostly silicon, silicon is divided into monocrystalline silicon, polycrystalline silicon and amorphous silicon 3 categories. Recently, the so-called CIGS systems such as Cu, In, Ga and Se, CdTe solar cells and thin-film solar cells have also been put on the market, which has increased the conversion efficiency and reduced the cost, attracting attention. Now 90% of the raw materials used in the production of solar cells using polysilicon,
