Conditions for efficiency improvement and optimization in CdS/CdTe solar cells prepared by hot wall technique (HWT) are discussed in this paper. CdS/CdTe solar cells with and without incorporated back layer contact (BC) have been studied by current-voltage and capacitance-voltage measurements. Analysis reveals the cells without back layer contact seriously suffer in fill factor (FF) due to J-V rollover in dark and illumination. Also, the FF is limited by a light-dependent shunt and series resistances. The efficiency of both types of cells is limited by a light-dependent shunt/series resistances and compensation mechanism of CdTe layer. |
