Problems solved by technology

The anti-reflection coating prepared by this method has low hardness, and although the initial moisture resistance is good, the process is complicated. After coating, it needs to be treated with a mixed gas of ammonia and hexamethyldisilazane for a second time, and the hydrophobic group is in the After decomposing under the action of sunlight and ultraviolet rays, the hydrophobic performance is weakened, and the moisture-proof performance becomes poor.

Abstract

The invention relates to the technical field of glass, in particular to high-hardness moisture-proof antireflection solar glass and a preparation method thereof. The solar glass comprises a solar cellpackaging glass substrate and a high-hardness moisture-proof antireflection coating layer arranged on the surface of the solar cell packaging glass substrate, wherein the high-hardness moisture-proofantireflection coating layer is prepared from a high-hardness moisture-proof antireflection coating solution; and the high-hardness moisture-proof antireflection coating solution is prepared from thefollowing raw materials in parts by weight: 2 to 5 parts of organic polysilazane, 88 to 98 parts of an aprotic organic solvent, 0.01 to 1 part of a silane coupling agent, 0.01 to 1 part of a catalystand 0.5 to 5 parts of diphenyl dimethoxy silane. The high-hardness moisture-proof antireflection solar glass has high hardness, moisture resistance and light transmittance, film surface damage and power generation efficiency attenuation in the installation or use process of an assembly are reduced, the weather resistance of the coated glass is enhanced, and the service life of the coated glass isprolonged.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a high-hardness, moisture-proof and anti-reflection solar glass and a preparation method thereof. Background technique [0002] Solar photovoltaic is one of the clean energy sources with the most development potential at present. Relevant practitioners in various countries are making every effort to develop various advanced technologies and new products, hoping to improve the photoelectric conversion efficiency. Among the factors that determine the conversion efficiency of crystalline silicon solar cells, the most important determinant is the crystalline silicon technology in photovoltaic components, followed by the solar glass that protects photovoltaic components. Relatively speaking, improving the optical properties of solar glass is easier than improving the conversion efficiency of crystalline silicon cells, and the cost is slightly lower. At present, most solar glass manufac...
