Defect Clusters: Approaches for Overcoming Their Detrimental Impact on Solar Cell Performance

Defect Clusters: Approaches for Overcoming Their Detrimental Impact on Solar Cell Performance

NREL

Research output: Contribution to conference › Paper

Abstract

Our analyses show that defect clusters can lower the efficiency of multicrystalline silicon (mc-Si) solar cells by 2 to 4 absolute percentage points. This large loss can be recovered if impurities precipitated at the defect cluster sites can be gettered. We describe a new technique for gettering precipitated impurities.
