Photo)electrochemical analysis of electrosynthesized fibrous cadmium indium selenide (CdIn2Se4) thin films

Abstract Electrosynthesized cadmium indium selenide (CdIn 2 Se 4 ) 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 CdIn 2 Se 4 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.
