Abstract

The invention discloses a preparation method of a photovoltaic glass surface antireflection film, which is characterized by comprising the following steps of firstly, preparing inorganic-organic hybrid silicasol; secondly, coating; thirdly, hydrophobic treatment; and fourthly, solidification treatment. Compared with the prior art, the invention has the advantages that the film-substrate cohesion between an antireflection film and substrate photovoltaic glass is stronger, and therefore, the wiping resistance of the coated photovoltaic glass surface antireflection film is enhanced; a layer of hydrophobic group with low surface energy is formed on the surface of the antireflection film, and therefore, the corrosion of moisture to a film microstructure is reduced, and the long service life ofthe coated photovoltaic glass is ensured; and the invention has low whole process cost and simple technical route and is suitable for industrial and large-scale application.

Description

technical field

[0001] The invention relates to a method for treating the surface of photovoltaic glass, in particular to a method for preparing an anti-reflection film on the surface of photovoltaic glass. Background technique

[0002] The worldwide energy shortage and environmental protection pressure have greatly promoted the development and application of solar cell photovoltaic modules. With the continuous optimization of solar cells and photovoltaic components, the conversion efficiency of crystalline silicon cells in solar photovoltaic components is close to the limit value. It is very difficult to continue to improve the efficiency of the cells themselves to increase the actual output power of photovoltaic components, but it can be achieved through Other ways to increase efficiency, such as increasing light intensity. At present, people generally use a photovoltaic glass with a low iron content as the packaging glass for photovoltaic modules of solar cells. This gla...
