Influence of the optical and recombination losses on the efficiency of CdS/CdTe solar cell at ultrathin absorber layer
Abstract: The effect of low thickness of CdTe on optical, front, and back recombination losses and hence on the efficiency of a CdS/CdTe solar cell is studied theoretically in this work. It is found that the optical losses are about 23%–24% and depend weakly on CdTe thickness. The recombination losses are about 28% at dCdTe = 0.45 m and decrease ... إقراء المزيد
