Abstract
Multi-crystalline silicon ingot was prepared by directional solidification method using metallurgical grade silicon as raw materials. The influence of impurities and crystalline defects in mc-Si on the minority carrier lifetime and resistivity was investigated. The results indicate that both grain boundary and impurities play important roles in the deterioration of the minority carrier lifetime.
