We report the transparent conducting mixed SnO2-CuO oxides films fabricated by chemical spray pyrolysis technique (CSPT). The effects of the film thickness on the optical absorptance of the TCO films are assessed. Optical absorption measurements were studied by UV-VIS technique in the wavelength ranges 400-1100 nm. Characteristics and optical constants of the mixed oxides thin film such as refractive index, extinction coefficient, real and imaginary parts of dielectric constant have been studied. The optical conductivity and the skin depth are increased with increasing the film thickness.
