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.
