Abstract: Indium doped mixed sulphide films were prepared by the spray pyrolysis technique on glass substrates by spraying aqueous solutions of Cadmium chloride, Zinc Chloride, Indium Trichloride and Thiourea. The Indium doping concentration was varied from 0.025\% to 2.00\% by weight. It is found that the film thickness increases with increase in doping concentration. The electrical and optical properties of the films such as dark conductivity thermoelectric power and optical absorption were studied. The films prepared with 1\% by weight doping concentration show high thermoelectric power and dark conductivity.
