Photoelectrochemical activities of lead sulfide semiconductor prepared by cyclic voltammetry

The tremendous amount of research that has been carried out in the field of semiconductor photoelectrochemistry and inorganic solar cells during the past three decades continues to provide fundamental insights and practical applications[1]. Lead sulfide is narrow band gap semiconductor with band gap energies of 0.41 ev. Many useful applications [2] such as photodetectors, optoelectronic devices and solar cells have been cited by various researchers. We try to investigate about electrochemical preparation of PbS, it’s properties as an photoelectrode under light irradiation. For this reason a convenient electrochemical method to prepare PbS in aqueous phase on the electrode surface is cyclic voltammetry technique.
