Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that the existing solar glass anti-reflection coating cannot adapt to the working environment of field pollution, and to invent a solar glass anti-reflection coating with self-cleaning and anti-reflection functions at the same time, so as to stabilize and improve the power generation efficiency of solar cells and Reduce solar cell maintenance and management costs
[0008] The main reason why the surface of solar anti-reflection glass is easy to be polluted is that glass is an insulator, and friction and adsorption cause the glass surface to have a positive charge. When the surface static charge cannot be quickly eliminated, it is particularly easy to electrostatically adsorb negatively charged dust.

Abstract

The invention discloses solar glass self-cleaning antireflection paint and a production method thereof. In the solar glass self-cleaning antireflection paint, poly silicon dioxide is used as a main antireflection component, low reflection titanium dioxide is used as an auxiliary antireflection component and a photocatalyst, antimony doped tin oxide, titanium phosphate, silicon phosphate, phosphoric acid and antimony doped tin phosphate are used as a self-cleaning synergist, an antistat and an antireflection membrane enhancer, and deionized water is used as a solvent. The production method comprises the step: a porous silicon dioxide shell generated through ethyl silicate hydrolysis is covered with the anatase titanium dioxide photocatalyst, the antimony doped stannic oxide antistat and other synergist components. The problem that antireflection performance and the self-cleaning performance of conventional solar glass self-cleaning antireflection paint can offset each other is solved, the power generating efficiency of a solar cell can be improved and stabilized greatly, and the maintenance management cost of the solar cell can be reduced.

Description

technical field [0001] The invention relates to a self-cleaning antireflection coating for solar glass and a production method thereof, in particular to a water-based solar energy coating containing a low-reflection titanium dioxide self-cleaning component coated on the surface of nano-silicon dioxide and a nano-antimony tin phosphate antistatic component. The self-cleaning anti-reflection coating for glass and its production method belong to the field of new materials and new energy. Background technique [0002] Crystalline silicon solar cell modules are generally composed of solar glass cover plate coated with anti-reflection film, solar cell silicon wafer, battery back plate and EVA film, which are glued and pressed together, and then installed into a fixed frame. The visible light transmittance of solar cell module packaging glass is generally 91.6%, and the single surface reflectance of solar glass is about 4%. If a layer of anti-reflection film with a thickness of 12...
