Photo-electrochemical performance of Cd1−xPbxS (0≤x≤1) thin films

This paper discusses chemical synthesis of Cd1−xPbxS (0≤x≤1) thin film layers and their photo-electrochemical properties with special reference to PEC parameters. Previously optimized conditions were used for the deposition. The electrode/electrolyte interfaces were then formed between the Cd1−xPbxS thin film layers and a sulphide/polysulphide (1 M) redox couple and investigated through the various photo-electrochemical (PEC) properties to assess suitability to convert solar energy into electrical energy. Increase in short circuit current (Isc) and open circuit voltage (Voc) was observed with increased composition and attain maximum at x=0.175. Power conversion efficiency and fill factor were found to be 0.163% and 46.2% respectively for the composition parameter x=0.175.
