晶体硅太阳电池硅片质量控制

Quality Control of Silicon Wafer for Crystalline Silicon Solar Cell

硅片作为太阳能电池片的载体,其质量好坏直接决定电池的转换效率。晶体硅太阳电池硅片制备过程包括铸锭多晶硅制备、直拉单晶硅制备、硅片切割等,在工艺路线一定的情况下,通过对原料处理过程、晶体硅生长过程及硅片加工等过程规范操作、严格控制各项工艺参数指标有效控制硅片质量。

The silicon wafer as a carrier of solar cell,whether its qualiy is better or not directly decide the transfer efficiency of a cell. The preparation course of crystalline silicon solar cell includes polysilicon ingots, Czochralski silicon,multi-line cutting. While the course of craftwork is fixed,the quality of crystalline silicon can be controlled by standardizing materials disposing course, czochralski silicon＇s growing course and strictly regulating all kinds of parameter index.
