Preparation and characterization of cadmium sulphide thin films prepared by vacuum evaporation deposition and chemical bath deposition

Abstract

Cadmium Sulphide CdS thin films play an important role in newlinefulfilling the smaller and faster is the technological imperative of our times newlineCadmium Sulphide is a II VI compound semiconductor Cadmium Sulphide newlinecompounds has a higher melting point and larger band gap than those of the newlinecovalent semiconductors of comparable atomic weights CdS thin films can newlinebe prepared by vacuum evaporation deposition and chemical bath deposition newlineDeposition techniques and substrate temperature has a strong effect on the newlineelectrical and structural properties of CdS thin films newlineOne of the most important applications is the conversion of solar newlineenergy into electrical energy by the meaning of the photovoltaic effect CdS newlinethin films would produce small amounts of electric current when exposed to newlinelight newline newline newline
