Influence of substrate temperature on photovoltaic parameters of CdS/DdTe/Te solar cells fabricated by Close Space Sublimation

Thin film CdS/CdTe solar cells were fabricated by close space sublimation at the substrate temperature ranging from 300degC plusmn 5degC to 340 plusmn 5degCdegC. The best photovoltaic parameters were achieved at substrate temperature 320degC and source temperature 610degC. The open circuit voltage and current density changes significantly with the substrate temperature and depends on the substrate temperature. The open circuit voltage and current density achieves 0, 81 V and 22, 75 mA/cm², respectively. CdS/CdTe solar cells with an efficiency of 9, 56% were obtained.
