In this study, the optical characteristics of zinc oxide (ZnO) thin nano films, deposited by the spray pyrolysis method have been investigated. A quartz substrate was heated to 350 oC in order to deposit a thin coating of ZnO. The film's structural properties were examined by X-ray diffraction (XRD) analysis, and its optical properties were determined by transmittance spectra; these properties can be fine-tuned by UV-Vis. spectroscopy to suit the film's intended uses in solar energy conversion and photovoltaic solar cell devices. Based on the results obtained by XRD, the deposited film is wurtzite, which has a hexagonal structure and a preferred orientation along the (002) crystal plane, as well as a broadened peak. Very high absorption values (90%) were observed in the ZnO nano-films. Further research on the ZnO nano-films revealed an optical band gap of 2.84 eV. These findings underscore the potential of spray pyrolysis-deposited ZnO nano-films for optoelectronic applications.
