EFFECT OF REDOX SOLUTIONS ON OPTOELECTRONIC PROPERTIES OF CADMIUM SELENIDE FILMS
Abstract
Cadmiumselenide films of variable composition have been prepared using electrochemical codeposition method. Photoelectroactivityof cadmium acetate solution usingpolysulphide solution, Ce3+/Ce4+ and Fe2+/Fe3+ redox couples has been studied and compared with its activity in the I3-/I2. Electrochemical impedance measurements have been used to estimate capacitance of the deposited thin films for the calculation of charge carrier density. Current voltage measurements have also been used for the characterization of these films. Dependence of photoelectroactivity of these thin films on light intensity, pH of redox solutions and the externally applied electrical bias has been investigated
