Abstract:The presence of light elements like C ,N ,O has wide influence on the properties of solar-grade silicon .Since silicon is the dominating raw material of solar cells ,the purity of crystalline sili-con has significant influence on electrical properties of solar cells .In this paper ,the research progress on carbon ,nitrogen and oxygen on the presence ,distribution ,formation mechanism and process con-trol was summarized .An outlook for light elements research in silicon was also proposed ,the combi-nation of different purification methods to control and eliminate impurities in silicon is worth paying attention to investigate ,and the further research on the behavior of C ,N ,O in silicon can also im-prove silicon quality .
