The light energy can be more effectively utilized by plating an antireflection film on the surface of the photovoltaic glass, the antireflection film is a porous silicon dioxide film with the thickness of about 120nm, and the initial antireflection performance of the photovoltaic coated glass mainly depends on the refractive index of the film layer and the porosity of the film layer. The porosity is mainly determined by the amount of pore-forming agent in the antireflection coating liquid and the sintering condition in the film forming process, and the smaller the refractive index is, the higher the porosity is, and the higher the light transmittance of the coated glass is. But high porosity can cause surperficial open pore structure to a certain extent, and inside this kind of open pore structure can not effectually prevent that steam, dust etc. from invading glass, cause the hole to block up, and the refracting index increases, and the luminousness decay is serious, and weatherability and dirt resistance are relatively poor.
The method for preparing the antireflection film in the prior art mainly comprises a sol-gel method, a chemical vapor deposition method, catalytic etching and the like, wherein the sol-gel method is widely applied due to the characteristics of simple equipment, low cost and the like.
