摘    要:全面介绍了太阳能级多晶硅的生产技术现状及有代表性的新工艺、新技术的研究动态。太阳能级多晶硅生产技术主要包括西门子法、硅烷法和冶金法。冶金法因工艺简单、投资少、能耗低获得广泛的关注,但目前其产品达不到太阳能级硅的质量要求。展望未来,西门子法仍将是生产高纯度多晶硅的主流技术。

Abstract: The production status of solar grade silicon and development studies of its new representative processes and technologies were comprehensively introduced. The production technologies of solar grade silicon mostly include Simens process, silane process and metallurgical process. For simple process, lower investment and lower energy consumption, metallurgical process is given extensive attention, but the products cannot meet the quality requirements of solar grade silicon at present. Simens process will still be the mainstream process in the production field of the high purity silicon in the future.
