Spray pyrolysis technique was used to deposit thin films of Tin oxide (SnO2) on glass substrates using as precursor SnCl2.2H2O solution. The samples were prepared for different thickness at annealing temperature of 500�C for 2 hours. The film thickness was controlled with the different numbers of sprayed.The surface of the films was characterized morphologically by Scanning Electron Microscopy (SEM). The characterization by X-Ray Diffraction showed well defined bands that indicate a SnO2rutile phase.Propriety optical studies were made by comparing UV-Visible transmittance spectra of the different films and Van der Pauw of four-point technique was used for the electrical measurements. The optical and electrical parameters permitted to calculate: the band gap, refractive index, film resistance and figure of merit, in order to evaluated Transparent Conductive Oxide (TCO) properties. Film thicknesses were obtained from fringes features in the transmittance spectra.
