Solar cells are currently fabricated from a variety of silicon-based materials.Now the major silicon material for solar cells is the scrap of electronic grade silicon(EG-Si).But in the current market it is difficult to secure a steady supply of this material.Therefore,alternative production processes are needed to increase the feedstock.In this paper,EBM is used to purify silicon.MG-Si particles after leaching with an initial purity of 99.88%in mass as starting materials were used.The final purity of the silicon disk obtained after EBM was above 99.995%in mass.This result demonstrates that EBM can effectively remove impurities from silicon.This paper mainly studies the impurity distribution in the silicon disk after EBM.
