摘要
Cu2O thin films were prepared on a Cu substrate with a room-temperature water bath in which a HF and HNO3 mixture was used as the soak solution and dilute nitric acid was used as the deposit liquid. The influences of the preparation conditions, such as the molar ratio of HNO3:HF, the reaction temperature and the reaction time on the photoelectric performance of the sample under simulated sunlight, were explored. The results of x-ray diffraction, scanning electron microscopy, energy dispersive analysis and x-ray photoelectron spectroscopy indicate that the surface of the Cu substrate was oxidized to Cu2O, which serves as a nanocomposite thin film. Additionally, the formation of a binary Cu2O/Cu nanocomposite in optimized conditions exhibits its potential for excellent photoelectric properties under simulated solar illumination.
