Photoelectrochemical studies on polycrystalline CdS (chemical bath deposition) and CdSe (chemical bath and electro deposition) thin film electrodes

Abstract

The photoelectrochemical behaviour of polycrystalline CdS and CdSe thin film electrodes prepared by a chemical bath deposition (CBD) method has been examined in an aqueous sulfide—polysulphide electrolyte. The open circuit voltage, short circuit current, flat band potentials, and efficiencies are reported. The CBD technique is simple and promising for the preparation of polycrystalline metal chalcogenides. The behaviour of CdSe prepared by electrodeposition has also been examined.
