Abstract
Thin films of CdSe and Fe-doped CdSe (Fe:CdSe) were deposited onto stainless steel substrates by electrodeposition technique. The photoelectrochemical investigations have been carried out using the cell configurations CdSe/1 M (Na 2S–S–NaOH)/C and Fe:CdSe/1 M (Na 2S–S–NaOH)/C for studying the current–voltage ( I– V) characteristics in dark and under illumination, photovoltaic output, spectral response, photovoltaic rise and decay characteristics. The studies reveal that films are n-type conductivity. The junction quality factor in light ( n l), series and shunt resistance ( R s and R sh), fill factor (FF) and efficiency ( η) for the cell have been estimated. After Fe doping, efficiency and FF of PEC solar cell is found to be improved from 0.34% and 31.12 to 1.80% and 35.78, respectively.
