Abstract

Zinc oxide (ZnO)thin film (300nm) was successfully manufactured using thermal evaporation method. XRD, UV spectroscopy, AFM were used to study film characterization which was deposited on a glass substrate. Transmittance and reflection data of the film versus wavelength were investigated using UV-VIS Spectrophotometer. Over 50% transmittance values have been observed in the NIR region. Optical constants were calculated and the estimated energy gap (3.4 eV)of the prepared film. XRD results showed that films made from ZnO were crystalline with hexagonal wurtzitestructure. The measurements of (I-V) properties of the dark current and light I-V show that this variation has a high-voltage open circuit (Voc), which makes it suitable for application in highly efficient ZnO / p-Si solar cell.
