Abstract
Preparation of CuO thin films by spray method is having wide range of applications. In this the CuO films prepared using various concentration of aqueous solution containing CuCl2.2H2O and double distilled water. The XRD, UV-VIS spectra was recorded. XRD results shows that the film is poly crystalline nature. The refractive index, optical band gap, film thickness were calculated by using the UV-VIS spectra. This CuO films are suitable for solar cell fabrications.. Optical spectrum shows that the films are having high transmittance and low absorption in the visible region. Ultra violet-visible spectra shown that the optical energy gaps for CuO films were estimated in the range 1.4 and 1.7 eV.
