摘要:
以熔融石英颗粒作为籽晶的全熔法铸锭工艺已成为当前高效多晶硅的重要生产方法。但由于熔融石英为异质籽晶且为无定形结构,因而其引晶效果并不理想。采用方石英籽晶代替生产所用的熔融石英籽晶辅助高效多晶硅的初期形核及晶粒生长。结果显示:硅锭底部的初始晶粒得到明显细化,其平均粒径缩小约15.7%,且晶粒尺寸更加均匀,位错密度较熔融石英铸锭降低了21.5%,相应电池片的平均转化效率绝对提升近0.1%。
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.
