Problems solved by technology

[0003] When AZO film is used in thin-film solar cells, it is required to have high visible light transmittance and low resistance, and at the same time, it is also required to have a certain roughness (velvet) on the surface of the film to achieve the purpose of reducing reflection and anti-reflection. Surface AZO thin films are mainly prepared by post-sputtering corrosion and metal-organic chemical vapor deposition (MOCVD). Compared with vapor deposition, wet chemical method is a kind of thin film preparation method with simple process and low cost, which is suitable for large-area substrates. Uniform deposition, among which, the sol-gel method can control the doping at the molecular level, which is an ideal method for preparing doped ZnO transparent conductive films, but the AZO film usually prepared by the sol-gel method has a flat and smooth surface , the textured structure cannot be obtained. Literature and patent searches show that there is no report on the preparation of textured AZO films by the sol-gel method.

technical field [0001] The invention relates to a preparation method of an AZO transparent conductive film, in particular to a preparation method of an AZO transparent conductive film with a network suede surface. Background technique [0002] Transparent conductive oxide (TCO) film, as a photoelectric information material with high visible light transmittance and low resistance, is widely used in thin-film solar cells, flat panel displays, sensors and various optoelectronic devices. Al-doped ZnO transparent conductive film (ZnO: Al, referred to as AZO), is one of the TCOs that have been studied more in recent years. AZO and traditional TCO films such as ITO (In 2 o 3 : Sn), FTO (SnO 2 : F) It has comparable photoelectric properties, and has the advantages of easy availability, environmental friendliness, and stable performance in hydrogen plasma.
