Description
Technical field
The present invention relates to photovoltaic technology field, and in particular to a kind of solar battery sheet.
Background technique
In scientific and technological flourishing and advocating environment protection epoch, the application of solar panels is quite extensive.Solar battery sheet is a kind of
The device converted solar energy into electrical energy, has the advantages that environmental protection and energy saving, the working efficiency of solar battery sheet and sunlight
Strong and weak related with receiving area, in the prior art, sunlight received by solar battery sheet is exactly solar battery sheet
Surface area, due to the limitation of various objective condition, the size of solar panels is certain, therefore influences the conversion of solar battery sheet
Efficiency cannot make full use of sunlight.
Summary of the invention
In order to overcome the shortcomings of that background technique, the present invention provide a kind of solar battery sheet, mainly solve it is existing too
The problem of cannot making full use of sunlight to influence the transfer efficiency of solar battery sheet of positive energy cell piece, the solar-electricity
Chip architecture design in pond is rationally simple, by lens refraction principle, can receive the sunlight except solar battery sheet surface,
Sunlight can be more fully utilized, the transfer efficiency of cell piece is improved, while playing a protective role to solar battery sheet, prolongs
Long cell piece service life.
The technical scheme adopted by the invention is that: a kind of solar battery sheet, including crystal silicon plate, EVA layer A and TPT backboard
Layer, the crystal silicon plate two sides are respectively equipped with EVA layer A and EVA layer B, and the EVA layer A another side is equipped with TPT backsheet layer, the EVA
The layer upper surface B is equipped with glass-base, and in protrusion globoidal structure, lower surface is planar structure setting for the glass-base upper surface,
The planar structure of the glass-base lower surface is arranged in parallel with crystal silicon plate, and sky is equipped between the glass-base and EVA layer B
Between, the space length between the glass-base and EVA layer B is 3-10mm.
The upper surface the EVA layer B is sticked and has antireflective coating.
The beneficial effects of the present invention are: effectively improving existing solar battery sheet due to taking above-mentioned technical proposal
Cannot make full use of sunlight to influence solar battery sheet transfer efficiency the problem of, which sets
Meter is rationally simple, by lens refraction principle, can receive the sunlight except solar battery sheet surface, can more sufficiently
Utilize sunlight, improve the transfer efficiency of cell piece, while playing a protective role to solar battery sheet, extend cell piece make
Use the service life.

Fig. 2 is the structural schematic diagram of glass-base 5 in Fig. 1.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawing and specific implementation
The present invention will be further described for example.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, a kind of solar battery sheet, including crystal silicon plate 1, EVA layer A2, EVA layer B 4 and TPT backboard
Layer 3,1 two sides of crystal silicon plate are respectively equipped with EVA layer A2 and EVA layer B 4, and the EVA layer A2 another side is equipped with TPT backsheet layer 3,
4 upper surface EVA layer B is equipped with glass-base 5, and the glass-base 5 preferentially selects colourless transparent glass material, glass base
Layer 5 upper surface in protrusion globoidal structure, lower surface be planar structure be arranged, the planar structure of 5 lower surface of glass-base and
Crystal silicon plate 1 is arranged in parallel.Space is equipped between the glass-base 5 and EVA layer B 4.The glass-base 5 and EVA layer B 4 it
Between space length be 3-10mm, according to lens imaging principle, sunlight is directed in 6 convex configuration of glass-base, by glass
The refraction of glass base 6 forms optically focused, simultaneously because ignition-face area is greater than the principle of the area of plane, cell piece is received greater than its surface
The amount of product glazing, improves solar panels transfer efficiency.
4 upper surface EVA layer B is sticked and has antireflective coating 6, reduces the reflection of light, and the light for improving solar battery sheet turns
Change efficiency.
What the present invention effectively improved existing solar battery sheet cannot make full use of sunlight to influencing solar energy
The problem of transfer efficiency of cell piece, the solar battery sheet is reasonable in design simple, passes through lens refraction principle, Ke Yijie
The sunlight except solar battery sheet surface is received, sunlight can be more fully utilized, improve the transfer efficiency of cell piece,
It plays a protective role simultaneously to solar battery sheet, extends cell piece service life.
Embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but can not
Therefore limitations on the scope of the patent of the present invention are interpreted as.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
