Problems solved by technology
[0005] However, most of the existing reflective coatings on the surface of coated glass are single-layer structures, which have technical defects such as poor reflectivity, poor heat insulation effect, poor adhesion, easy to fall off, and low hardness of pencil scratches. Due to the problem of poor stability, it cannot well meet the technical development needs of the double-glass photovoltaic cell module industry

Description
technical field [0001] The invention belongs to the technical field of solar energy materials, and relates to a high-reflection coating for a solar battery glass plate and a preparation method thereof. Background technique [0002] With the increasing shortage of energy and the deterioration of the environment, human beings are facing serious environmental and energy problems. At present, in the development and utilization of various new energy sources, solar energy utilization is the most promising field. A solar cell is a semiconductor device with photoelectric conversion characteristics. Its function is to convert solar energy into electrical energy, store it in a battery or drive a load to work. The backsheet of traditional crystalline silicon solar cell modules has a certain water permeability. The water vapor passing through the backsheet will quickly decompose the EVA resin to release acetic acid, which will lead to electrochemical corrosion inside the module, which ...
