Abstract

P-CuO /n-Si was prepared and studied with respect to Drop casting method  at  200°C temperature, it was concluded that energy band gap of CuO films is (1.6)eV calculated from optical properties. AFM reveal that the generated CuO Films have ball-shape with perfect homogeneity, the measurements of the XRD revealed that the CuO were of cubic crystal structure, the responsively photo detector after deposited CuO showed an increase in response.Keywords: CuO, Structure properties, AFM, Optical properties, Solar cell.

Abstract

This study deals with the study of the structural and visual properties of NiO and Li Doped NiO films in different percentages (0.02, 0.04, 0.06, 0.08% mol).Thin films of NiO were deposited on glass substrates at 300 ° C and 150 nm using droplet casting technique. X-ray diffraction (XRD) showed that multi-crystalline films had a cube structure with a preferred orientation along the length of (111). The tonic stimulator did not change between 0.02, 0.04, 0.06 and 0.08% Grammy% of the preferred trend. The average grain sizes of crystals classified from XRD data were found in the range of 15.62 - 37.52 nm. Atomic Force Microscope (AFM) data shows that the film surface is extremely smooth. The photovoltaic permeability of pure NiO membranes is 72% in the visual and x-ray regions (NIR), which is important for their applications as window layers in solar cells.Keywords: Nickel oxide, XRD, AFM, grain sizes, thin film.
