Crystalline Zinc Indium Selenide Thin Film Electrosynthesis and its Photoelectrochemical Studies

A room temperature electrochemical synthesis of Zinc Indium Selenide (ZnIn2Se4) thin films has been carried out. The films were polycrystalline and exhibited n-type conductivity. ZnIn2Se4 films were found to be photoactive in polysulphide solution. The photo electrochemical (PEC) studies of these films have been carried out using current-voltage (I-V) characteristics, power output characteristics, spectral response, Mott-Schottky plot and electrochemical impedance spectroscopy (EIS).
