Method For Improving Performance Of Solar Grade Silicon

In order to minimize the cost and maximize the availability of Silicon solar cells the manufacturers of these cells use less pure forms of Silicon feedstock known as solar grade Silicon (SoG-Si). However impurities in SoG-Si (such as iron and other metals) decrease the conversion efficiencies of solar cells.To address this problem researchers at UC Berkeley have developed a method for reducing metal impurity point defects in SoG-Si feedstock and thereby improve its conversion efficiency in solar cells. This novel method minimizes the performance degrading impact of metals such as Fe Cr Ti and V.
