Problems solved by technology

[0007] At present, the glass plates used for solar panels are basically tempered glass or white glass. After the solar panels have been used for a long time, various A stubborn stain that affects its light transmittance, thereby affecting the absorption of light by the solar panel, so it needs to be cleaned manually on a regular basis, which adds a lot of trouble
At the same time, with long-term exposure, solar radiation will cause the aging of the glass, which will eventually affect the efficiency and life of the solar panel

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to a glass plate used for solar cell panels and a preparation method thereof. Background technique [0002] As a clean and renewable new energy source, solar energy is increasingly favored by people and plays a wide role in people's life and work. Since the solar energy irradiated on the earth is very huge, the solar energy irradiated on the earth in about 40 minutes is enough for the energy consumption of human beings all over the world for one year. Therefore, it can be said that solar energy is a truly inexhaustible and inexhaustible energy source. Moreover, solar power generation is absolutely clean and does not produce pollution. [0003] The use of solar energy is mainly divided into several aspects: small solar power plants for households, large-scale grid-connected power plants, building-integrated photovoltaic glass curtain walls, solar street lights, wind-solar hyb...
