虽然世界上光伏电池在发电领域仅占很小部分,但其重要性不容忽视。在市场上多晶硅和单晶硅占主导,从硅锭的边角料加工出的单晶硅即可满足太阳能电池的需要,因为太阳能电池不需要像半导体器件用硅晶圆那样高的超纯度。目前,半导体工业消费量大约为多晶硅产量的2/3,余下的1/3为太 Although the world photovoltaic cells in the field of power generation only a small part, but its importance can not be ignored. In the market, polycrystalline silicon and monocrystalline silicon dominate. The monocrystalline silicon processed from the ingot of silicon ingot can meet the needs of solar cells because the solar cells do not need ultra-high purity like silicon wafers for semiconductor devices. Currently, the semiconductor industry consumes roughly two-thirds of polysilicon production and the remaining one-third is too much
