Disclosed is a CuO/Se composite film, in which Se with low melting point (221&#xb0; C.) and strong photosensitivity is introduced into CuO, providing the film with fewer defects and excellent optical, electrical and photoelectric properties. In the preparation method of the invention, Se is introduced into CuO and melted by low-temperature annealing, and then the molten Se can infiltrate CuO to eliminate or reduce defects in the CuO film such as voids and dangling bonds, thereby improving optical, electrical and photoelectric properties of the film and overcoming the shortcomings that CuO has poor crystallinity, high melting point and is decomposed at a high temperature.
