Abstract

A versatile and cost effective spray pyrolysis technique was used to prepare the Zinc Oxide (ZnO) thin film on a glass substrate. The feature of the obtained film was characterized using Glancing incidence angle X-ray diffraction (GIXRD), Scanning Electron Microscope (SEM), UV-Visible Spectroscopy and Photoluminescence (PL). GIXRD confirmed that the structure of the ZnO film was polycrystalline having wurtzite structure. SEM image revealed root-like morphology on the surface of ZnO thin film and the shortest root diameter was about 91.2 nm. From UV-Visible spectrum an optical transmittance of about 85% in the visible region and direct optical band gap energy of 3.2 eV was calculated. The PL analysis showed that the film exhibited a strong emission peaks at violet and green region. From the characterized results, spray pyrolysis is the viable technique to deposit ZnO thin film on a glass substrate, which can be used as a transparent layer in thin film solar cells.
