Purification of Metallurgical Grade Silicon to Solar Grade for Use in Solar Cell Wafers

A pyrometallurgical process for manufacturing solar grade silicon (SOG-Si) from metallurgical grade silicon (MG-Si) was developed. Metallic elements in MG-Si such as iron, titanium and aluminum, which show low partition coefficients, were removed by directional solidification practice. Phosphorus re...
