摘要
Superlattice consisting of 10 alternate layers of a-Si with QDs and SiNX are incorporated as i-layer in a p-i-n solar cell using HWCVD method. Superlattice with QDs showed absorption coefficient in the range of similar to 10(5)-10(4) cm(-1). Calculated optical bandgap of the SL with QDs (similar to 1.84 eV) is higher than the SL without QDs (similar to 1.79 eV) and this is attributed to QCE. The cells with QDs showed I-SC = 1.806 mu A and V-OC = 2 5 mV. Increase in I-SC of cells is attributed to increase in tunneling current due to decrease in SiNX thickness. Low V-OC has been attributed to the thin SiNX layers, the defects and the interface states which result in recombination.
