With the popularization and application of photovoltaic modules, the photovoltaic modules gradually enter urban curtain walls, roofs and private homes from power stations in mountainous areas, seasides and deserts, but the existing photovoltaic modules have the defects of strong light reflection, dazzling, light pollution and the like, so that the application of the photovoltaic modules in the cities is limited, photovoltaic module manufacturers also put forward higher requirements on the photovoltaic modules in the areas such as the curtain walls, the roofs and the highway sides, and the photovoltaic module cover plate glass is required to have the dazzling-proof and anti-dazzle effects, so that the solar anti-dazzle glass comes across the requirements.
The simplest method for reducing the glass glare phenomenon is to form a suede on the surface of the glass to enable light to form diffuse reflection, light trapping and transmission, so that the purpose of preventing glare is achieved. At present, there are several methods for producing anti-glare glass:
1) the method is characterized in that the method is simple and the corrosion speed is high. However, the method has the defects that the harm is great, hydrofluoric acid is extremely corrosive acid, can greatly damage and pollute human bodies, the atmosphere and the soil environment, is strictly controlled and used by China, and can only achieve the anti-dazzle effect without the anti-reflection effect. For example, in the patent "anti-glare and visible light antireflection dual-function coated glass and the preparation method thereof", the anti-glare film layer is obtained by adopting a weak acid corrosion method.
2) Plating an anti-dazzle coating, atomizing the anti-dazzle coating solution into liquid beads through atomization spraying, coating the liquid beads on the surface of glass, and forming a rough surface with accumulated particles after curing and drying to achieve the anti-dazzle effect.
