Zinc oxide (ZnO) thin films have been deposited at various deposition temperatures ranged from 350˚C to 500˚C and constant spray time by spray pyrolysis technique onto glass substrates. X-ray diffraction (XRD) results showed that the all films are polycrystalline with hexagonal wurtzite structure and exhibite (002) preferential orientation. All films exhibit high transmittance up to 90 % in the visible region. The value of prepared ZnO films resistivity decreased with increasing the deposition temperature. Sprayed ZnO film deposited at 450˚C shows the best opto-electronic properties.
