Abstract

A manufacturing method for a cheap transparent conducting film includes processing steps as the follows: preparing film coating solution, cleaning base material, coating film, electrode making, annealing and electrified aging formation. The manufacturing method is characterized in that the formula of the film coating solution is that the main material zinc acetate is 88g, dopant alchlor is 5g, high-temperature resistance stabilizer titanium chloride is 2g, high-temperature resistance stabilizer lead acetate is 4g, lead escape inhibitor manganous chloride is 1g, cosolvent acetic acid is suitable in proportion, and solvent distilled water is 500 to 1000g. The preparing steps of the film coating are as follows: A, using the acetic acid to acidize the distilled water, and covering for future use; B, weighing the titanium chloride according to the formula and covering for future use; C, weighing other components to be dissolved in the acidized distilled water, dripping slowly the titanium chloride solution to be sufficiently and uniformly mixed, and covering for future use; cleaning the base material; and carrying out film coating, electrode making and electrified aging formation of the base material. Compared with the existing transparent oxide conducting film, the cheap transparent conducting film has the advantages of cheap raw material, excellent cost performance and low cost, and is suitable for making the transparent conducting film.

Description

technical field [0001] The invention belongs to an ohmic resistance transparent conductive film characterized by material or material properties, in particular to a manufacturing method of a cheap transparent conductive film. Background technique [0002] According to the book "Transparent Conductive Oxide Thin Film" published by Higher Education Press: ZnO material has photoelectric, piezoelectric and ferroelectric properties, and has been widely studied in the past 20 years. As a piezoelectric material, ZnO has a large coupling coefficient. In terms of photoelectric performance, it is used in optical sensors because of its fast response time and strong sensing ability. After doping with aluminum (Al) and gallium (Ga) , ZnO has excellent light transmission and conductivity, and ZnO doped with lithium (Li) or magnesium (Mg) can be used as a ferroelectric material. As a multifunctional semiconductor material, ZnO has been applied in the fields of flat panel displays, solar c...
