Description
Summary:•Obtained highest efficiency for the electrodeposited CdIn2Se4 photoanode in PEC cell.•Analysis of photoanode performance using electrochemical impedance spectroscopy.•Theoretical modeling of energy band diagram to analyze performance of PEC cell. Electrosynthesized cadmium indium selenide (CdIn2Se4) thin films were (photo) electrochemically analyzed by current–voltage characteristics, photoresponse, speed response, electrochemical impedance study, and capacitance–voltage characteristics. The improved photoconversion efficiency of electrosynthesized CdIn2Se4 thin film-based photoelectrochemical cell explained with the help of theoretical modeling of energy band diagram and equivalent circuit model of the impedance spectra of the photoelectrochemical cell.
