Abstract

The invention relates to the field of chemical engineering, and specifically relates to a coating solution for reducing glass surface light reflection. The coating solution is a mixed solution obtained by dispersing an ester substance, water, an acid and an amine reagent in an alcoholic solvent. After applying the coating solution for reducing glass surface light reflection of the invention on a glass surface and carrying out heat treatment, the glass surface reflectivity can be reduced by more than 2%, thus effectively increasing light transmittance of the glass. The coating solution for reducing glass surface light reflection of the invention can be applied in fields needing increasing glass transmittance or reducing surface reflection, such as solar cell glass or architectural glass surfaces for preventing light pollution.

Description

technical field [0001] The invention relates to the field of chemical engineering, in particular to a coating solution for reducing light reflection on glass surfaces. Background technique [0002] With the continuous development of green energy and environmental protection, solar cells have made great progress in recent years. Solar cells mainly use crystalline silicon to generate electricity under the irradiation of sunlight. The power generation efficiency of ordinary solar cells is below 18%. In order to further improve the power generation efficiency of the battery, the transmittance of sunlight can be increased by reducing the surface reflection of the glass covered on the crystalline silicon. The light reflectance of each surface of ordinary glass is about 4%, which makes the light transmittance of the glass It is difficult for the rate to exceed 92%. [0003] The surface reflectance of the glass is related to the refractive index of the glass. Since the refractive i...
