[Abstract]:Organic-inorganic hybrid perovskite solar cells have attracted wide attention in photovoltaic field in recent years because of their advantages of strong light absorption and long carrier diffusion length. Inorganic nio thin film has become an important research direction of perovskite battery as a hole transport layer in the structure of the cell. Nio thin films were prepared by solution spin-coating method. The effects of nio films on the performance of perovskite batteries were optimized at different sintering temperatures and different concentrations. The optical and electrical properties of nio thin films and corresponding batteries were observed and analyzed by means of scanning electron microscope X-ray diffraction, UV-Vis spectrophotometer, current-voltage measurement and optical quantum efficiency. The results show that nio thin films prepared by solution spin-coating method have good coverage and very low surface roughness. When the concentration of prefabricated nio solution is 0.05 mol / L nio sintering temperature is 500 鈩，
