Abstract

Cadmium sulfide is an important material used in thin−film photovoltaic devices. The deposition of cadmium sulfide films by single indirect source evaporation through a gas discharge is investigated and the effects of the discharge on film properties and deposition rates are discussed. The discharge has a direct and advantageous effect on both the electrical and optical properties of the CdS thin films. These properties may be altered by suitable choices of evaporation and gas discharge parameters. Control of these properties is important in device applications and it is proposed that this technique is a practical method for controlling properties of CdS thin films.
