Abstract
The invention relates to an anti-glare photovoltaic module which comprises a rear panel layer. The anti-glare photovoltaic module is characterized in that a main ethylene vinyl acetate (EVA) layer is distributed on the rear panel layer, and a cell is distributed on the main EVA layer. Simultaneously, an auxiliary EVA layer is distributed on the cell, a glass layer is arranged on the EVA layer, and an antireflection film layer is arranged on the glass layer. Accordingly, by means of the antireflection film layer, a coarse layer and an embossing layer, certain light transmittance can be satisfied, light reflectivity can be effectively reduced, reflected light intensities are reduced, and destruction effects of light pollution are avoided, so that the anti-glare photovoltaic module can be applicable to special application occasions such as airports; and the anti-glare photovoltaic module is simple in structure and easy to popularize and manufacture.
Description
Technical field
The present invention relates to a kind of photovoltaic module, relate in particular to a kind of anti-dazzle photovoltaic module.
Background technology
With regard to photovoltaic module common on the existing market, its structure and material that adopts is: toughened glass+EVA+ battery sheet+EVA+ backboard.Specifically, wherein toughened glass generally adopts photovoltaic to use super white patterned toughened glass, and therefore in the actual use of photovoltaic module, the surface of assembly forms direct reflection especially easily, thereby causes reflected glare.Limited assembly on the airport etc. to the use of light pollution than higher important events.
Summary of the invention
The object of the invention is exactly the problems referred to above that exist in the prior art in order to solve, and a kind of anti-dazzle photovoltaic module is provided.
The object of the invention is realized through following technical scheme:
A kind of anti-dazzle photovoltaic module; Include backsheet layer; Wherein: be distributed with main EVA layer on the described backsheet layer, be distributed with the battery sheet on the described main EVA layer, be distributed with layer on the described battery sheet from EVA; Describedly be provided with glassy layer from the EVA layer, described glassy layer is provided with antireflective coating.
Further, above-mentioned a kind of anti-dazzle photovoltaic module, wherein: be provided with rough layer between described glassy layer and the antireflective coating.
Further, above-mentioned a kind of anti-dazzle photovoltaic module, wherein: be distributed with granule crystal in the described rough layer.
Further, above-mentioned a kind of anti-dazzle photovoltaic module, wherein: describedly between EVA layer and glassy layer, be distributed with embossed layers.
Again further, above-mentioned a kind of anti-dazzle photovoltaic module, wherein: be distributed with pleated structure in the described embossed layers.
The advantage of technical scheme of the present invention is mainly reflected in: rely on the existence of antireflective coating, rough layer and embossed layers; When satisfying certain light transmission rate; Can effectively reduce the reflection of light rate, reduce catoptrical intensity, remove the destruction effect of light pollution from.Thus, can be applied in particular application such as airport.And simple structure of the present invention is easy to promote and makes.
Description of drawings
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical scheme of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of requirement protection of the present invention.In the middle of these accompanying drawings,
Fig. 1 is the organigram of this anti-dazzle photovoltaic module.

Embodiment
A kind of anti-dazzle photovoltaic module as shown in Figure 1 includes backsheet layer l, and its special feature is: be distributed with main EVA layer 2 on the backsheet layer 1 that the present invention adopts.Further that is distributed with battery sheet 3 on main EVA layer 2.Simultaneously,, on battery sheet 3, be distributed with, be provided with glassy layer 5 from EVA layer 4 from EVA layer 4 in order effectively to promote whole optical property.And, for when satisfying optical property, reduce the generation of light pollution, prevent reflected glare, glassy layer 5 is provided with antireflective coating 6.Specifically, the refractive index of antireflective coating 6 is 1.2-1.45, makes the transmitance of light improve 2%, and reduces the reflection of light rate, has reduced catoptrical intensity.
With regard to the present invention's one preferred implementation; Because glassy layer 5 surfaces form direct reflection especially easily; When causing reflected glare, influence the work of follow-up battery sheet 3, between glassy layer 5 and antireflective coating 6, be provided with rough layer 7, roughness is approximately 1.2-1.8.Like this, the direct reflection in the original primary event is changed into diffuse reflection, reduced catoptrical formation approach.Certainly, in order to improve irreflexive effect, be distributed with granule crystal in the rough layer 7.
Further, because glassy layer 5 is too smooth, single dependence rough layer 7 possibly also unnecessary reflection can occur, between EVA layer and glassy layer 5, is distributed with embossed layers 8.Like this, cooperate the rough layer 7 that exists, further guarantee irreflexive effect.Specifically, be distributed with pleated structure in the embossed layers 8 of employing, the reflection of light rate can better reduce like this.
Can find out through above-mentioned character express, behind employing the present invention, rely on the existence of antireflective coating, rough layer and embossed layers; When satisfying certain light transmission rate; Can effectively reduce the reflection of light rate, reduce catoptrical intensity, remove the destruction effect of light pollution from.Thus, can be applied in particular application such as airport.And simple structure of the present invention is easy to promote and makes.
