方石英籽晶辅助生长高效多晶硅的研究
Cristobalite-seeded growth of high performance multicrystalline silicon ingot
摘要
Abstract
Fused quartz particles have been widely used as heterogeneous seeds to assist the growth of high performance multicrystalline silicon(HP mc-Si)ingot in industry.However,the crystal quality is not ideal because of the heterogeneous and amorphous structure of the fused quartz seeds.Cristobalite particles instead of fused quartz seeds was used to assist nucleation and grain growth of the HP mc-Si ingot.Results showed that the initial grain size of the cristobalite seeded ingot was obviously refined.The average grain size decreased by 15.7%,and the size was more uniform.The dislocation density reduced by 21.5% in comparison with fused quartz seeded ingot,and the average conversion efficiency of the solar cells increased about 0.1% in absolute value.关键词
