Problems solved by technology

However, the thickness of zinc aluminum oxide must exceed 400 nanometers (usually the thickness of indium tin oxide is only more than 100 nanometers), its electrical properties are relatively good, and the production of thicker films requires longer coating time, making industrial production efficiency low , the cost of film manufacturing is high, and the amount of materials used is also correspondingly increased

Abstract

The invention relates to a transparent conductive film consisting of metal silver / metal oxide and a preparation method thereof. The transparent conductive film consists of a substrate, a film buffer layer, a film conductive layer and a transparent conductive film protective layer which are arranged layer by layer from bottom to top. The conductive layer is a metal silver film of which the thickness is between 3 and 10 nanometers; the thickness of the film buffer layer is between 10 and 30 nanometers; and the thickness of the transparent conductive film protective layer is between 20 and 50 nanometers. In the preparation method, the magnetron sputtering coating technology is adopted, a conveyor belt drives the substrate to move in vacuum cavities, and the buffer layer, the conductive layer and the transparent conductive film protective layer are coated layer by layer on the substrate layer in turn in three vacuum cavities respectively. The film prepared by the method has the optical transmittance in a visible light area over 80 percent, and the surface resistance less than 10 ohms. The thicknesses of the conductive layer and the transparent conductive film protective layer are all thin, materials are saved, the required coating time is short, and high production efficiency is achieved in industrial mass production.

Description

technical field [0001] The invention relates to a transparent conductive film and a preparation method thereof, in particular to a transparent conductive film composed of a metal silver layer and a metal oxide layer and a preparation method thereof. Background technique [0002] Transparent conductive film is a film with high optical transparency and good conductivity, which has been widely used as electrode materials for various display devices and optoelectronic devices such as solar cells. The currently commonly used transparent conductive film materials are indium tin oxide (tin-doped indium oxide) and zinc aluminum oxide (aluminum-doped zinc oxide); wherein, indium tin oxide is the most widely used due to its excellent performance and easy preparation, but, Indium is a rare metal. With the extensive use of indium oxide, the price of indium continues to rise, so it is urgent to find new transparent conductive materials to replace indium oxide. Zinc is abundant in nature...
