Example Embodiment

[0017] Example 1:

[0018] Mix 0.12mol of water, 0.04mol of ammonia and 3mol of anhydrous ethanol for heating. When the temperature reaches the set temperature of 35℃, add 0.04mol of ethyl orthosilicate, keep the temperature at a constant temperature, and continue to stir for 21 hours to obtain a dispersion of silica nanoparticles Then, a polystyrene latex ball with a diameter of 105 nm is slowly added to the silica nanoparticle dispersion and stirred, with a volume ratio of 2.6:1, to obtain a blended solution, which is ready for use.

[0019] Roll coating is used to coat the cleaned photovoltaic glass surface to obtain a transparent film. The coated photovoltaic glass was sintered at a temperature of 500°C for 18 minutes to obtain high-efficiency antireflection and antireflection glass.

Abstract

The invention discloses a preparation method of efficient increased-transmission and antireflection glass, which comprises the steps as follows: (1) the molar ratio of raw materials comprising silicon sources to deionized water to catalysts to solvents is 1:0.05 to 10:0.01 to 10: 10 to 300, the deionized water, the catalysts and the solvents are firstly mixed, heated and stirred at a uniform speed, when an obtained mixture is heated to 20 to 50 DEG C, the silicon sources are added to the mixture and stirred with the mixture for 2 to 40 hours at a maintained constant temperature and a uniform speed, and then silica nano-particle dispersion liquid is obtained; (2) polystyrene latex spheres are used as templates to be mixed with the silica nano-particle dispersion liquid obtained in the step (1) at a volume ratio of 1:5 to 5:1, and then a blended solution is obtained; (3) the blended solution obtained in the step (2) is coated on the surface of a photovoltaic glass substrate; and (4) the film-coated photovoltaic glass substrate is placed in a temperature condition of 300 to 700 DEG C to be sintered for 5 to 30 minutes, and then the efficient increased-transmission and antireflection glass is obtained. The preparation method has the advantages that the binding force between an antireflection film and the substrate is strengthened, and the durability of the thin film is improved; and besides, through controlling the diameter and the mixing proportion of the polystyrene latex sphere templates, the reflectivity of the thin film is accurately regulated, so that an obvious increased-transmission effect is achieved.
