Abstract
The utility model belongs to the photovoltaic glass technology field, and discloses a photovoltaic glass, characterized in that an antireflection film is coated on the upper surface of a super white float glass, and a silica antireflection film is coated on the lower surface. Because the double antireflection films play a part in antireflection on the surfaces of the photovoltaic glass, the light transmittance of the photovoltaic glass of the utility model is increased by more than 3%, the highest light transmittance can reach 95.2%, the power of a packaged solar assembly is increased by more than 3%, and can be increased by 3.5% furthest.
Description
Technical field
The utility model belongs to the photovoltaic glass technical field, is specifically related to a kind of photovoltaic glass.
Background technology
As the cleaning new energy of a kind of green, environmental protection, photovoltaic generation has obtained using widely at present, and has development space widely.Solar components is the core in the photovoltaic generating system.The photoelectricity dress of the solar components (like crystal silicon solar assembly, glass substrate thin film solar assembly) of industrialization at present changes efficient and is mainly decided by the efficient of the battery sheet (or basis material) in the solar components.
Along with people's is updated battery sheet (or basis material) system technology, and its photoelectric conversion efficiency is also improving constantly, and has reached higher value at present, under the condition of prior art, efficient is improved very difficulty again.
The another one method that improves solar components is to increase to be radiated at the light intensity on the battery sheet (or basis material); And the solar battery sheet encapsulation is all to use a cover-plate glass; When sunlight incident, be bound to stop the sunlight of incident; Make to be reflected and to be absorbed at the upper and lower surfaces of cover-plate glass that the effective rate of utilization that improves solar energy through the performance that improves glass cover-plate is a good method by glass into the light that shines.
Better performances also is that the cover-plate glass that generally adopts is a photovoltaic glass at present, and the iron-holder of this photovoltaic glass is low, and general the requirement is lower than 120ppm, but the light transmittance of this glass can not surpass 91.5% yet, still has the sunlight about 8.5% not obtain utilizing.
The method of transmitance that improves sunlight is a lot, can assign to reduce the absorption to sunlight through changing the one-tenth of forming photovoltaic glass, can also on photovoltaic glass, apply antireflective coating.
At present, apply individual layer SiO at photovoltaic glass surface
2The method that antireflective coating increases light transmittance is generally used, but the light transmittance that applies the glass of this antireflective coating generally is lower than 93.5%, and the power recruitment of the solar components that encapsulates generally has only 1.5%-1.8%.
The utility model content
The purpose of the utility model is the deficiency to existing technology, the photovoltaic glass that a kind of high transmission rate is provided and has the automatically cleaning effect.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of photovoltaic glass is coated with antireflective coating at the upper surface of ultra-white float glass, and lower surface is coated with SiO
2Antireflective coating.
Wherein, the antireflective coating of upper surface coating is TiO
2And SiO
2Compound antireflective coating, its thickness are 100-150nm.
Described SiO
2The thickness of antireflective coating is 100-120nm.
Described ultra-white float glass thickness is 3-5mm.
This pair antireflective coating plays the antireflective effect at photovoltaic glass surface, thereby the light transmittance of photovoltaic glass is increased more than 3%, and light transmittance is up to 95.2%; Simultaneously, because upper surface TiO
2And SiO
2Compound antireflective coating has Superhydrophilic, thereby photovoltaic glass has the automatically cleaning effect.
The utlity model has following advantage:
(1) light transmittance and power improve.Under the complex reflex membrane interaction, the photovoltaic glass light transmission reaches more than 94%, and the solar components power that encapsulates increases more than 3%, the highlyest increases by 3.5%;
(2) have Superhydrophilic, automatically cleaning is effective, can reduce the clean and maintenance to solar components in the use.
Description of drawings
Fig. 1 is the structural representation of a kind of photovoltaic glass of providing of the utility model embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of photovoltaic glass is coated with TiO at the upper surface of ultra-white float glass 1
2And SiO
2Compound antireflective coating 2, lower surface is coated with SiO
2 Antireflective coating 3.
Wherein, described TiO
2And SiO
2The film thickness of compound antireflective coating 2 is 100-150nm, is preferably 117nm.
Described SiO
2The film thickness of antireflective coating 3 is 100-120nm, is preferably 103nm.
Described ultra-white float glass thickness is 3-5mm, is preferably 3.2mm.
This photovoltaic glass and common photovoltaic glassy phase ratio, light transmittance increases more than 3%, reaches as high as 95.2%, is equipped to solar components, the highest increase by 3.506% of power.
In addition, this TiO
2And SiO
2Compound antireflective coating has Superhydrophilic, and water droplet can reach 120 ° at the contact angle of upper surface, therefore has the automatically cleaning effect.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
