Abstract
The utility model relates to a solar battery plate. Thereby current solar battery plate's the problem that can not the make full use of sunlight influences solar battery plate's conversion efficiency has mainly been solved. The crystal silicon plate two sides is equipped with EVA layer A and EVA layer B respectively, and EVA layer A another side is equipped with TPT backsheet layer, and EVA layer B upper surface is equipped with glass substrate, the glass substrate upper surface is salient ARC structure, and the lower surface sets up for planar structure, and the planar structure and the crystal silicon plate parallel arrangement of glass substrate lower surface are equipped with the space between glass substrate and the EVA layer B, and the A upper surface subsides of EVA layer are equipped with antireflection coating. This solar battery plate structural design is reasonable simple, and the sunlight outside the solar battery plate surface can be received to scioptics refraction principle, can be more abundant utilize the sunlight, improve the conversion efficiency of battery piece, play guard action, extension battery piece life to solar battery plate simultaneously.
Description
Technical field
This utility model relates to field of photovoltaic technology, is specifically related to a kind of solar battery sheet.
Background technology
In the flourishing and epoch of advocating environment protection in science and technology, the application of solar panels is the most extensive.Solar battery sheet is a kind of device converted solar energy into electrical energy, the advantage with environmental protection and energy saving, the work efficiency of solar battery sheet is relevant with the power of sunlight and receiving area, in prior art, sunlight received by solar battery sheet is exactly the surface area of solar battery sheet, and due to the restriction of various objective condition, the size of solar panels is certain, therefore affect the conversion efficiency of solar battery sheet, it is impossible to make full use of sunlight.
Utility model content
In order to overcome the deficiency of background technology; this utility model provides a kind of solar battery sheet; mainly solve existing solar battery sheet can not make full use of sunlight thus the problem that affects the conversion efficiency of solar battery sheet; this solar battery sheet reasonable in design is simple; by lens refraction principle; the sunlight outside solar battery sheet surface can be received; sunlight can be utilized more fully; improve the conversion efficiency of cell piece; solar battery sheet is played a protective role simultaneously, extend cell piece service life.
This utility model be the technical scheme is that a kind of solar battery sheet, including crystal silicon plate, EVA layer A and TPT backsheet layer, described crystal silicon plate two sides is respectively equipped with EVA layer A and EVA layer B, described EVA layer A another side is provided with TPT backsheet layer, described EVA layer B upper surface is provided with glass-base, described glass-base upper surface is in protruding globoidal structure, lower surface is that planar structure is arranged, the planar structure of described glass-base lower surface be arranged in parallel with crystal silicon plate, it is provided with space between described glass-base and EVA layer B, space length between described glass-base and EVA layer B is 3-10mm.
Described EVA layer B upper surface has been sticked antireflective coating.
The beneficial effects of the utility model are: owing to taking technique scheme; effectively improve existing solar battery sheet can not make full use of sunlight thus the problem that affects the conversion efficiency of solar battery sheet; this solar battery sheet reasonable in design is simple; by lens refraction principle; the sunlight outside solar battery sheet surface can be received; sunlight can be utilized more fully; improve the conversion efficiency of cell piece; solar battery sheet is played a protective role simultaneously, extend cell piece service life.

In figure 1, crystal silicon plate；2, EVA layer A；3, TPT backsheet layer；4, EVA layer B；5, glass-base；6, antireflective coating.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further.
As shown in Figure 1 with Figure 2, a kind of solar battery sheet, including crystal silicon plate 1, EVA layer A 2, EVA layer B 4 and TPT backsheet layer 3, described crystal silicon plate 1 two sides is respectively equipped with EVA layer A 2 and EVA layer B 4, described EVA layer A 2 another side is provided with TPT backsheet layer 3, described EVA layer B 4 upper surface is provided with glass-base 5, described glass-base 5 preferentially selects colourless transparent glass material, glass-base 5 upper surface is in protruding globoidal structure, lower surface is that planar structure is arranged, and the planar structure of described glass-base 5 lower surface be arranged in parallel with crystal silicon plate 1.It is provided with space between described glass-base 5 and EVA layer B 4.Space length between described glass-base 5 and EVA layer B 4 is 3-10mm, according to lens imaging principle, sunlight is directed in glass-base 6 convex configuration, optically focused is formed through glass-base 6 refraction, simultaneously because ignition-face area is more than the principle of the area of plane, cell piece receives the amount more than its surface area glazing, improves solar panels conversion efficiency.
Described EVA layer B 4 upper surface has been sticked antireflective coating 6, reduces the reflection of light, improves the light conversion efficiency of solar battery sheet.
What this utility model effectively improved existing solar battery sheet can not make full use of sunlight thus the problem that affects the conversion efficiency of solar battery sheet; this solar battery sheet reasonable in design is simple; by lens refraction principle; the sunlight outside solar battery sheet surface can be received; sunlight can be utilized more fully; improve the conversion efficiency of cell piece, solar battery sheet is played a protective role simultaneously, extend cell piece service life.
Every technical staff's notice: although this utility model describes according to above-mentioned detailed description of the invention; but invention thought of the present utility model is not limited to that utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
