Preparation and characterization of polycrystalline n-CdSe photoelectrode

Abstract

Thin layers of polycrystalline p-CdSe were prepared by the simultaneous eletrodeposition of cadmium and selenium from cadmium sulfate and selenious acid in a sulfuric acid solution at pH 0-1 on a titanium substrate. The adherence of the layers to the substrate, stoichiometric ratio of Cd:Se and photovoltaic property of the film depend upon the molar ratio of CdSO/sub 4/ and H/sub 2/SeO/sub 3/ and current density as well as on the pH and temperature of the electrolysis bath. On increasing the current density or the ratio of CdSO/sub 4/:H/sub 2/SeO/sub 3/ in the electrolysis bath, the Cd:Se of the electrodeposit increased. The semiconductor films so prepared were annealed at 550/sup 0/C in a nitrogen atmosphere, followed by etching in an acid solution and then used to construct the photo-electrochemical cell, Ti/CdSe/Na/sub 2/S-Na/sub 2/S/sub x/(aq.)/Pt, and the current-voltage curves have been studied. 11 references.
