Abstract

The invention provides a preparation method of large-area transparent conducting film glass. The preparation method of the large-area transparent conducting film glass comprises the following steps: (a) coating a coating liquid precursor on a glass substrate, so as to form a tin oxide doped transparent conducting oxide film on the glass substrate; and (b) carrying out heat treatment on the glass substrate coated with the oxide film so as to form transparent conducting film glass; and coating the liquid precursor on the glass substrate by utilizing a liquid phase roller coating method. By changing a formula of precursor mixed liquor, quality of a film layer can be controlled, and functions of the film layer can be improved. The preparation method of the large-area transparent conducting film glass has the advantages that a technology is simple, equipment cost and raw material costs are low, operation is easy, and industrial mass production can be facilitated; a tin oxide doped transparent conducting oxide film is plated on a moving glass surface by adopting an appropriate liquid precursor, and the obtained transparent conducting film has the characteristics of high transmittance, high conductivity and a suede structure and can be widely applied to thin-film solar cells and low-radiation energy-saving glass.

Description

technical field [0001] The invention relates to a method for preparing transparent conductive film glass in a large area, in particular to coating a tin oxide-doped transparent conductive oxide film on the surface of moving glass by using a liquid phase roller coating method. The film is mainly used in thin film solar cells and Low-emissivity energy-saving glass and other fields. Background technique [0002] With the energy crisis and the increasingly serious environmental pollution caused by traditional energy sources, the development of renewable clean energy has become one of the major strategic issues in the world. Solar energy is an inexhaustible clean energy source. Therefore, research and development Utilizing solar energy has become an energy strategic decision for sustainable development of governments around the world. Among them, amorphous silicon (a-Si:H) thin-film solar cells occupy the primary position in thin-film solar cells because of their low cost and ea...
