Properties of electrodeposited cadmium sulfide films for photovoltaic devices with comparison to CdS films prepared by other methods

Films of CdS for photovoltaic devices were electrochemically deposited on t in oxide coated glass substrates at different conditions. The films were fo und to be smooth and uniform with a small grain size. X-ray diffraction mea surement and analysis indicated a hexagonal phase rather than the cubic pha se. The surface composition of the films was investigated by Auger Spectros copy. Electrochemical deposition parameters were studied to obtain the opti mum conditions for the best CdS films. Our films are compared from the pinh ole number and particulate point of view with the films prepared by other m ethods.
