Abstract

This invention discloses a method for preparing SnO2 / TiO2 composite nanofilm used for photoelectric conversion. The method comprises: (1) cleaning the substrate; (2) preparing TiO2 sol and SnO2 sol; (3) coating the substrate with a layer of TiO2 sol film, drying, and coating the substrate with a layer of SnO2 sol film; (4) repeating the above procedures to obtain multiple composite film; (5) placing in a muffle furnace, heating, cooling with distilled water, and drying to obtain the composite film. The composite film has low cost and simple process, and better photoelectric conversion property than that of single composition film.

Description

technical field [0001] The invention belongs to the technical field of functional composite thin film materials, and relates to a preparation process of a nanocomposite thin film, in particular to a nano-SnO nanometer for photoelectric conversion. 2 / TiO 2 Preparation process of composite film. Background technique [0002] Due to the excellent optical, electrical and magnetic properties of nano-semiconductor functional films, they have attracted much attention. where TiO 2 Semiconductors are particularly prominent, on the one hand, TiO 2 Abundant sources and large output; on the other hand, due to TiO 2 Non-toxic, stable chemical properties, can be used as a photocatalyst for photolysis of water and photodegradation of organic matter, and can be used as a photoelectrode material for photoelectric conversion. SnO 2 Thin film is also a kind of functional film, which has a wide range of applications in gas sensing, humidity sensing, and optical technology. Nanoization, ...
