dc.description.abstracttIn the present paper, the structural, optical and electrical properties of zinc oxide thin films were studiedbefore and after annealing temperature at 500◦C. The ZnO thin films were sprayed on glass substrates at350◦C, which were heated using the solar cells method. Polycrystalline films with a hexagonal wurtzitestructure with (0 0 2) preferential orientation corresponding to ZnO films were observed. It can be foundthat the good crystallinity are achieved in the films annealed at 500◦C. All films exhibit an average opticaltransmittance about 95% measured by UV–vis analyzer. The shift of optical transmittance towards highwavelength can be showed by the increases of band gap after annealing temperature which can be explainby the oxygen diffusion with annealing temperature. The electrical resistivity measured of our films inthe order 0.4 ( . cm).en_US
