Problems solved by technology

For example, the invention application with the publication number CN101913780 and the invention application with the publication number CN101805135 respectively provide anti-reflection double-layer film systems using high refractive index materials as the middle layer, but these film layers do not introduce TiO into the surface film. 2 , so there is no self-cleaning effect
So far, no research on double-layer coatings with anti-reflection and self-cleaning effects specifically for solar cell packaging glass has been found.

Abstract

The invention relates to the manufacturing field of solar cell packaging glass and in particular to antireflection coated glass with a self-cleaning effect. The antireflection coated glass comprises an ultra-white glass substrate; a high-refractive-index film layer is plated on the ultra-white glass substrate; and a self-cleaning functional film layer is plated on the high-refractive-index film layer. The invention further provides a preparation method of the antireflection coated glass with the self-cleaning effect. With the adoption of the antireflection coated glass provided by the invention, the self-cleaning effect of the coated glass can be ensured well, the purpose that the antireflection effect of the coated glass is better than that of a single-layer porous SiO2 antireflection film layer is fulfilled, the film plating technique is used in the manufacturing process, the coated glass is suitable for the large-area film plating of the solar cell packaging the raw material cost and the manufacturing cost are low, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of manufacturing packaging glass for solar cells, in particular to an anti-reflection coated glass with self-cleaning effect and a preparation method thereof. Background technique [0002] In recent years, with rising energy prices and people's growing awareness of environmental protection, countries around the world have introduced energy strategies to promote the utilization and development of new energy sources such as wind energy, biomass energy, and solar energy. Among them, solar photovoltaic power generation has the advantages of cleanness, safety, and wide application, and its development has also attracted much attention. my country's solar cell production capacity and installed capacity are huge, and photovoltaic power plants have entered the stage of large-scale construction. When the solar cell module is in use, the light must first pass through the uppermost encapsulating glass to enter the solar cell mo...
