Abstract: Zinc oxide (ZnO) thin films were deposited on glass substrates by spray pyrolysis technique decomposition of zinc acetate dihydrate in an ethanol solution with 30 mL of deposition rate, the ZnO thin films were deposited at two different temperatures: 300 and 350 C. The substrates were heated using the solar cells method. The substrate was R217102 glass, whose size was 30 17.5 1 mm3. The films exhibit a hexagonal wurtzite structure with a strong (002) preferred orientation. The higher value of crystallite size is attained for sprayed films at 350 C, which is probably due to an improvement of the crystallinity of the films at this point.The average trans mittance of obtain films is about 90%–95%, as measured by a UV–vis analyzer. The band gap energy varies from 3.265 to 3.294 eV for the deposited ZnO thin film at 300 and 350 C, respectively. The electrical resistivity measured of our films in the order 0.36 cm.
