【 摘 要 】

In this work, zinc oxide (ZnO) thin film has been assembled through the spin-coating method and accumulated on the p-type silicon (100) wafer. The ZnO nanoparticles (NPs) prepared via an entirely green procedure using Punica granatum (pomegranate) juice extract as an efficient chelating and capping agent. The coated ZnO NPs exhibited a homogeneous thin film over the silicon wafer. The crystal structure, surface morphology, alignment, and optical characteristics of ZnO thin film were studied through X-ray diffraction, field-emission scanning electron microscopy, EDX analysis, infrared spectroscopy, in addition to UV–vis spectra, correspondingly. The structure of the ZnO thin film was indexed as a wurtzite structure. UV–vis spectroscopy reveals that the alteration is straight bandgap energy ( E g ) and it is precisely 3.41 eV. The acquired ZnO thin films conceivably utilised as a photovoltaic material. The IR absorbance spectra indicate that the ZnO NPs spin-coated on the Si substrate improves the crystalline quality.
