Problems solved by technology
[0002] The conversion efficiency of photovoltaic modules can be improved by increasing the visible light transmittance. The traditional solution preparation process uses the method of stirring and mixing, so the transmittance of the coated glass has not been able to meet the demand, which affects the utilization of solar energy.

Embodiment Construction
[0017] The following embodiments of the present invention are described, and embodiment does not constitute limitation of the present invention:
[0018] Briefly, the present invention can be realized as follows;
[0019] The silicon oxide thin film preparation process is completed by adjusting the ratio and reaction sequence of tetraethyl orthosilicate, catalyst (ammonia water), glycerol, tetraethyl orthosilicate, silane coupling agent, absolute ethanol and deionized water. The solution is uniformly plated on the photovoltaic glass by a roller coating method. The roller coating machine is mainly composed of 35-40H hardness polyurethane rubber roller and chrome-plated electroplating roller. The photovoltaic glass enters the clockwise rotating rubber roller at a certain speed, and the liquid coating flow is controlled by the gap between the electroplating roller and the rubber roller. A silicon oxide film with a thickness of 125nm, a particle size of 10-15nm, a porosity of 61%...

The invention relates to the field of solar energy, particularly to a high transmittance photovoltaic glass and a porous silicon oxide antireflection film preparation method. The high transmittance photovoltaic glass is characterized in that the surface is provided with a layer of a porous silicon oxide antireflection film, wherein the thickness of the porous silicon oxide antireflection film is 125 nm, the particle size of the porous silicon oxide antireflection film is 10-15 nm, the porosity of the porous silicon oxide antireflection film is 61%, and the contact angle of the porous silicon oxide antireflection film is 30-35 DEG. The porous silicon oxide antireflection film preparation method is characterized by comprising: basic solution preparation; vibration treatment; and filtration, reflux and aging. With the technical scheme, the maximum transmittance is 95.3%. In addition, the conversion efficiency of the photovoltaic assembly is effectively improved through increase of the visible light transmittance; and the traditional solution preparation process adopts the stirring mixing method while the new method adopts the ultrasonic vibration machine to promote the interaction reaction between molecules so as to effectively reduce film plating solution production period and improve the production efficiency.
