Description
Technical field
The utility model relates to photovoltaic power generation technology field, relates in particular to a kind of solar module that light appears that reduces.
Background technology
Along with the development of photovoltaic technology, photovoltaic module application is more and more wider, and the region of installing is more and more wider.In common assembly, tend to apply an optical coating at the upper surface of front shroud glass, as antireflection coatings, form a kind of coated glass, more light can be entered in assembly and be utilized, reduce the reflections propagate of light on surface on glass.But light enters after component internal, also can thereby cause part light to leak to assembly outside due to the former of the reflections such as cell piece, cell piece gap area backboard, and not be utilized.In order further to strengthen the introducing of light, reduce light and run out of in assembly, industry also takes multiple means to realize, for example light trapping structure, it can make light be difficult to reflex to assembly outside.The assembly of existing sunken light function, to fall into light coating at surface-coated one deck of front shroud glass, make the light of component internal be difficult to be back to outside assembly through this coating, this sunken light coating often needs whole face to be covered in the upper surface of front shroud glass, and is not too suitable for conventional coated glass, because if use together with coated glass, due to the relation of light refraction, gain can be unobvious, and meanwhile, the mode of whole covering has also increased manufacturing cost greatly.
Therefore, be necessary to provide a kind of improved solar module to address the above problem.
Utility model content
The purpose of this utility model is to provide a kind of solar module that can effectively reduce light leak, improve light utilization.
For realizing above-mentioned utility model object, the utility model provides a kind of solar module, comprise cell piece and backboard that the glass of arranging successively from top to bottom, some employing weldings are connected in series, described glass has the inner surface and the outer surface that deviates from cell piece towards cell piece one side, between adjacent described cell piece, be formed with gap, on the inner surface of described glass, be provided with light trapping structure layer.
As further improvement of the utility model, described light trapping structure layer is arranged on the position that described inner surface is relative with described gap.
As further improvement of the utility model, described light trapping structure layer is coated on the inner surface of glass.
As further improvement of the utility model, the mode that described light trapping structure layer is connected with sideline by some cube structures forms, an angle of each cube structure arranges towards cell piece direction, and the summit at this angle of some cube structures is in the same plane.
As further improvement of the utility model, on the outer surface of described glass, be coated with antireflection coatings.
The beneficial effects of the utility model are: the utility model solar module by arranging light trapping structure layer on the inner surface of glass, can make on the cell piece surface or backboard of solar module inside, particularly the light reflection in gap to light trapping structure layer, make the light of reflection be difficult to see through light trapping structure layer and leak to the external world, and be reflected back cell piece surface by light trapping structure layer, can effectively increase thus the utilance of light, reduce light and appear; In addition, after the utility model is arranged on light trapping structure layer on the inner surface of glass, reliability is higher, and risk is lower, and can not have influence on the setting of the antireflection coatings on outer surface.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model solar module one preferred embodiment.
Fig. 2 is the upward view of the light trapping structure layer on the utility model solar module.
Embodiment
Below with reference to embodiment shown in the drawings, the utility model is described in detail.But these embodiment do not limit the utility model, the conversion in structure or function that those of ordinary skill in the art makes according to these embodiment is all included in protection range of the present utility model.
Please refer to Fig. 1 and Figure 2 shows that a preferred embodiment of the utility model solar module 100.Described solar module 100 comprises the glass 1 of arranging successively from top to bottom, cell piece 2 and the backboard 3 that some employing weldings (not shown) are connected in series.Between adjacent described cell piece 2, be formed with gap 21.
Described glass 1 has the inner surface 11 and the outer surface 12 that deviates from cell piece 2 towards cell piece 2 one sides.On described inner surface 11, be provided with light trapping structure layer 13.In the present embodiment, described light trapping structure layer 13 is coated on the inner surface 11 of glass 1.Certainly, this light trapping structure layer 13 is also on the submersible inner surface 11 that is located at glass 1.
In addition, in the present embodiment, described light trapping structure layer 13 is specifically arranged on the position that described inner surface 11 is relative with described gap 21, can not directly be absorbed by cell piece 2 because incide the light at these 21 places, gap on the one hand, after on reflexing to described light trapping structure layer 13, can the light of reflection be reflexed on cell piece 2 again by light trapping structure layer 13, reduce light leak, improve the absorptivity of cell piece 2 to light, and then improve the power of the utility model solar module 100; On the other hand, corresponding this light trapping structure layer 13 gap 21 is arranged, in the process laminated into type of solar module 100, can not have influence on cell piece 2.
With reference to Fig. 2 and in conjunction with shown in Fig. 1, in the present embodiment, the mode that described light trapping structure layer 13 is connected with sideline by some cube structures 131 forms, one of them angle 132 of each cube structure 131 is towards cell piece 2 direction settings, and the summit at this angle 132 of some cube structures 131 is in the same plane; Thus can be fully will reflex to light reflection on this light trapping structure layer 13 to cell piece 2.
Preferably, on the outer surface 12 of described glass 1, also can apply antireflection coatings (not shown), make thus more light can enter in solar module of the present utility model 100 and be utilized, further reducing the reflections propagate of light on glass 1 outer surface 12.
As known from the above, the utility model is by arranging light trapping structure layer 13 on the inner surface 11 at glass 1, can make on cell piece 2 surfaces or backboard 3 of the utility model solar module 100 inside, particularly the light reflection in gap 21 to light trapping structure layer 13, make the light of reflection be difficult to see through light trapping structure layer 13 and leak to the external world, and be reflected back cell piece 2 surfaces by light trapping structure layer 13, can effectively increase thus the utilance of light, reduce light and appear; In addition, after the utility model is arranged on light trapping structure layer 13 on the inner surface 11 of glass 1, reliability is higher, risk is lower, and can not have influence on the setting of the antireflection coatings on outer surface 12, when the utility model arranges described light trapping structure layer 13 and antireflection coatings at the same time, can reach dual antireflective and light leakage effect simultaneously.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present utility model; they are not in order to limit protection range of the present utility model, all do not depart from the equivalent embodiment that the utility model skill spirit does or change and all should be included in protection range of the present utility model within.
