The invention discloses a photovoltaic module glass, including photovoltaic glass and an anti-reflection film layer formed on the surface of the photovoltaic glass by an anti-reflection coating liquid, the anti-reflection coating liquid comprising a silane polymer and nano-microspheres, and the silane The raw materials of the polymer are silane, water, a catalyst and a solvent, and the raw materials of the nano-microspheres are active monomers, emulsifiers, initiators, stabilizers and water; the mass ratio of the silane polymer to the nano-microspheres is 1 : 0.2-0.4; the active monomer accounts for 10-20% of the total mass of the nano-microspheres; the silane polymer is prepared from silane by a sol-gel method under the condition of an acidic catalyst; the nano-microspheres It is prepared by emulsion polymerization method. The photovoltaic module glass of the present invention has an antireflection of more than 2.30% in the 380-1100 nm band, and the surface is closed, ensuring excellent dirt resistance and weather resistance. |
