Surface texturing solar glass self-cleaning anti-reflection structure and method

Abstract

The invention discloses a surface texturing solar glass self-cleaning anti-reflection structure and method, and aims to solve the problems that pollutants are easy to accumulate and the use efficiency of solar energy is reduced when a solar water heater and a solar cell panel are used outdoors for a long time. A solar energy glass surface structure is adopted, based on the lotus leaf effect, pollutants on the surface of the glass are self-cleaned, the reflection of the glass to sunlight is reduced by the sub-wavelength microstructure, and the use efficiency of solar energy is improved. The invention provides a surface texturing solar glass self-cleaning anti-reflection structure. The problem of compatibility of solar glass surface decontamination and solar energy utilization efficiency is solved, and the damage to the absorption part of the base material caused by direct etching of a solar cell piece or a solar heat collection piece or a solar heat collection tube by methods such as electron beam photoetching, plasma etching and reactive ion etching is also avoided.

Description

technical field [0001] The invention relates to the field of solar glass structures, in particular to a surface textured solar glass self-cleaning anti-reflection structure and method. Background technique [0002] In the prior art, solar glass is mainly used for cover tubes and cover plates used in the external structure of solar heat collectors and solar panels, and most of them are processed strengthened glass, which has the characteristics of wind pressure resistance, snow resistance, and improved performance to prevent Pollution and prevention of thermal cracking caused by sunlight, etc., but the thickness of conventional solar glass is 3.2mm or 4mm, which is heavy and increases material production costs; at the same time, the sunlight transmittance on the surface of traditional solar glass is low The pass rate is about 85%, the reflectivity is about 8%, the absorption loss is about 7%, and it is easy to cause light pollution. [0003] In the prior art, chemical reagen...

Problems solved by technology

However, on the one hand, if the solar glass is exposed to the outdoor atmosphere for a long time, the coating or coating will fall off; on the other hand, the chemical preparation of glass surface microstructure, chemical preparation of coating or coating and other methods have low processing efficiency.
