Abstract
The present utility model relates to a self-cleaning photovoltaic assembly with an anti-reflection film. The assembly is characterized in that a layer of packaging glass (2) is arranged on the outer surface of an effectively layer (1) of a solar energy battery of the photovoltaic assembly, an anti-reflection layer (3) is covered on the outer surface of the packaging glass (2), and a hydroxy self-cleaning layer (4) is covered on the outer surface of the anti-reflection layer (3). As the anti-reflection film is arranged on the packaging glass, light reflection can be effectively reduced, transmission can be increased, and light transmittance can be increased. The hydroxy surface layer arranged on the anti-reflection layer has super hydrophilicity, thus moisture can be spread completely and uniformly on the surface of a glass to completely infiltrate pollutants of the surface of the glass, the pollutants adhered to the glass can be took away through the gravity effect, rainwater can be adopted to realize self cleaning when sunlight is unavailable, and self-cleaning of the photovoltaic assembly can be realized.
Description
Technical field
The utility model relates to the automatically cleaning photovoltaic module, particularly a kind of automatically cleaning photovoltaic module with anti-reflection film.
Background technology
Photovoltaic module adopts high permeability, high-intensity glass material to encapsulate usually, and the photovoltaic array that its a plurality of assemblies constitute all uses in outdoor placement.Through long-term placement, can form the accumulation of one deck dust at assembly surface, along with the continuous increase of dust, the part sunlight will be stopped and can not get into the effective power generation part of assembly, and cause its photoelectric conversion efficiency constantly to reduce by dust.Therefore, the cleaning problems on photovoltaic module packaged glass surface is perplexing photovoltaic manufacturer and user always.
In order to improve the generating efficiency of photovoltaic module; Except that the conversion efficiency of improving technology raising battery itself; At present many manufacturers begin focus is placed on the transmitance that increases packaged glass, reduces on the reflection of glass surface rate, and then realize improving the purpose of overall optical photovoltaic assembly relative light photoelectric transformation efficiency.
At present, on field of photovoltaic power generation, begin to use some self-cleaning glass and anti-reflective glass.But common automatically cleaning or high permeability photovoltaic module can only satisfy automatically cleaning or anti-reflection needs, can not satisfy automatically cleaning and the anti-reflection specific function that both have concurrently simultaneously.The existing film that is used for having simultaneously on the solar cell package material automatically cleaning and anti-reflection two kinds of functions is to plate TiO on its surface
2And SiO
2Composite membrane, its automatic cleaning action mainly are to utilize TiO
2Under ultraviolet irradiation, because of photo-generated carrier has the automatic cleaning action that catalytic effect produces to making the surface, but this needs ultraviolet lighting, and TiO
2Crystal grain need be nano-scale, otherwise does not have photocatalytic effect.
The utility model content
The purpose of the utility model is that for addressing the above problem, the utility model proposes a kind of automatically cleaning photovoltaic module with anti-reflection film.Can have automatically cleaning and anti-reflection function simultaneously.
For realizing above-mentioned utility model purpose; The utility model proposes a kind of automatically cleaning photovoltaic module with anti-reflection film; It is characterized in that; Solar cell in this photovoltaic module effectively layer outer surface is provided with one deck packaged glass, and said packaged glass outer surface is coated with one deck antireflection layer, and said antireflection layer outer surface is coated with one deck hydroxyl automatically cleaning layer.
More preferably, the material of said antireflection layer employing is SiO
2Film or silester.Said antireflection layer adopts chemical vapour deposition technique to accomplish plated film.
The advantage of the utility model is; The anti-reflection film that is provided with on the packaged glass substrate of the solar cell in the automatically cleaning photovoltaic module of the utility model; Can effectively reduce the reflection of light, and increase transmission function, thereby can play the effect that increases light transmittance.The hydroxyl top layer that on antireflection layer, is provided with has super hydrophilicity.This characteristic can make moisture sprawl at glass surface fully equably; Soak into the glass surface pollutant fully; And will take away attached to pollutant on glass through action of gravity, and when not having sunlight, also can utilize rainwater to carry out automatically cleaning, thereby reach the self-cleaning effect of photovoltaic module.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the technical scheme of the utility model is carried out further detailed explanation.
As shown in Figure 1, Fig. 1 has the structure chart of the packaged glass in the automatically cleaning photovoltaic module of anti-reflection film for the utility model a kind of.The technical scheme that the utility model proposes is only done a little improvement to the packaged glass in the photovoltaic module; Solar cell in photovoltaic module effectively layer 1 outer surface is provided with one deck packaged glass 2; Said packaged glass 2 outer surfaces are coated with one deck antireflection layer 3, and said antireflection layer 3 outer surfaces are coated with one deck hydroxyl automatically cleaning layer 4 makes packaged glass possess automatically cleaning and anti-reflection function simultaneously.Wherein, the material of antireflection layer 3 employings is SiO
2Film or silester adopt common chemical vapour deposition technique to accomplish plated film.One deck hydroxyl automatically cleaning layer 4 in that the outer surface of antireflection layer 3 covers is realized automatic cleaning actions, its principle be since surface coverage hydroxyl, the surface has Superhydrophilic, and lipophile reduces.Around this principle, when not having sunlight, also can utilize rainwater to carry out automatically cleaning, and needn't to require solar window mouth layer be nanoscale crystal grain.
The anti-reflection film that is provided with on the packaged glass substrate of the solar cell in the automatically cleaning photovoltaic module of the utility model can effectively reduce the reflection of light, and increases transmission function, thereby can play the effect that increases light transmittance.The hydroxyl top layer that on antireflection layer, is provided with has super hydrophilicity.This characteristic can make moisture sprawl at glass surface fully equably; Soak into the glass surface pollutant fully; And will take away attached to pollutant on glass through action of gravity, and when not having sunlight, also can utilize rainwater to carry out automatically cleaning, thereby reach the self-cleaning effect of photovoltaic module.In practical application, has great economic outlook.
It should be noted last that above embodiment is only unrestricted in order to the technical scheme of explanation the utility model.Although the utility model is specified with reference to embodiment; Those of ordinary skill in the art is to be understood that; The technical scheme of the utility model is made amendment or is equal to replacement; The spirit and the scope that do not break away from the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
