Abstract:
Light-induced degradation (LID) due to boron-oxygen complex formation seriously deminishes the efficiency of p-type solar cells. The influence of dopants concentration, net doping and oxygen on the degradation process is investigated using a large variety of B and P compensated mc-Si ingots. Our experiments indicate that the trend of LID depends on the amounts of interstitial oxygen [Oi] and total boron [B]. No clear dependence was found on net doping.
