Transparent and conducting films of pure and antimony doped tin oxide have been prepared by spray technique. An optimum value of 18 ohm per unit area sheet resistance with 82% optical transmission has been obtained. Detailed studies of electrical and optical properties of these films have been made as a function of antimony concentration. The films behave like degenerate semiconductors. The low value of effective mass for undoped tin oxide films indicates a distortion in Fermi surface. The effective mass was found to increase with antimony concentration up to 6 mole % and the Fermi level shifted towards the conduction band. These films have been used as base contact layers in the special inverted configuration of sprayed Cu2S-CdS solar cells.
