Abstract :
Current-voltage and spectral response measurements have been made on high-efficiency CdTe/CdS thin film solar cells prepared by vacuum evaporation (n=9.6%). Analysis of the measurements indicate that these solar cells operate as p-n heterojunctions and the current transport in the junction region is dominated by Shockley-Read-Hall recombination in the CdTe. The analysis also indicates that the light-generated current varies with the applied voltage
