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.
Key words: solar grade silicon; Siemens process; silane; silicon
