Abstract

A new method named Chemical Physics (CP) method was developed to produce solar grade silicon feedstock at a company in China. In this paper the characteristic of the solar grade silicon made by CP method was analysed. The results show that the purity of solar grade silicon is above 5 N and most of impurities are below 0.0001 wt.%. Crystalline silicon solar cells were prepared using solar grade silicon wafers based on CP method. Average efficiency of the solar cells is about 15.05%, and the highest efficiency is 15.60% under AM1.5 illumination conditions. The light-induced degradation of the solar cells was examined. Degradation by up to 15% of the initial efficiency of the solar cells is detected. The solar cell results and light-induced characteristic show that the solar cells based on CP methods have desired performance and thus have the potential for large scale production.
