Abstract
The utility model provides a kind of solar module, stacked gradually formed by transparency carrier, upper sealant, solar cell device, lower seal layer, transparency carrier, by arranging reflector layer between solar cell device and lower seal layer, can effectively utilize the sunlight being irradiated to reflector layer surface, thus improve the efficiency of solar module.
Description
Technical field
The utility model relates to a kind of solar module.
Background technology
Usually, solar cell is stacked gradually formed by transparency carrier, upper sealant, solar cell device, lower seal layer, transparency carrier.Sunlight penetrates transparency carrier, upper sealant successively, is irradiated on solar cell device, and transform light energy is become electric energy thus generating by described solar cell device.
Described solar cell device comprises multiple cell sheet and welding, and described cell sheet is spaced, be arranged side by side, and each cell sheet upper surface realizes connecting by welding with the lower surface of neighboring unit cell sheet successively.For the interval region between cell sheet, sunlight directly penetrates transparency carrier, upper sealant, lower seal layer, transparency carrier, therefore can not arrive cell sheet surface thus the generating efficiency of raising solar module.
Utility model content
In view of this, the utility model provides a kind of solar module that effectively can improve generating efficiency.
The utility model provides a kind of solar module, described solar module is stacked gradually formed by transparency carrier, upper sealant, solar cell device, lower seal layer, transparency carrier, between solar cell device and lower seal layer, be also provided with reflector layer.
The utility model has following beneficial effect:
By arranging reflector layer between the solar cell device and lower seal layer of above-mentioned solar module, the sunlight on reflector layer surface can be irradiated to by usable reflection, sunlight through reflector layer reflection reflects through transparency carrier and upper sealant contact interface again, final arrival cell sheet surface is also absorbed by monomer cell piece, thus improves the generating efficiency of solar module.
Accompanying drawing explanation
Fig. 1 is the exploded view of the utility model solar module;
Fig. 2 is the vertical view of the utility model solar module;
Fig. 3 is the utility model solar module action principle schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of solar module 100, described solar module 100 is stacked gradually formed by transparency carrier 1, upper sealant 2, solar cell device 3, lower seal layer 4, transparency carrier 1, between solar cell device 3 and lower seal layer 4, be also provided with reflector layer 5.
Transparency carrier 1, mainly in order to cushion ambient pressure, can adopt the baseplate material in known solar module, such as the material of the light transmission such as glass, toughened glass.
Upper sealant 2 and lower seal layer 4 are mainly in order to seal and fixed solar cell device 3, known solar module transparent sealant can be adopted, the olefines encapsulants etc. such as such as vinyl-vinyl acetate copolymer numerical value (EVA), polyvinyl butyral resin (PVB), polyethylene.
Solar cell device 3 comprises multiple cell sheet 31 and welding 32, and described cell sheet 31 is spaced, be arranged side by side.As shown in drawings, the arrangement in matrix of multiple cell sheet 31, each cell sheet 31 upper surface realizes connecting by welding 32 with the lower surface of neighboring unit cell sheet 31 successively.Described cell sheet 31 can be monocrystalline silicon type photo-electric conversion element, polycrystalline silicon type photo-electric conversion element or amorphous silicon type photo-electric conversion element.Described welding 32 is arranged mainly for being electrically connected by neighboring unit cell sheet 31, and in addition, welding, by intersecting with the finger electrode 311 on cell sheet surface 31, has the effect of confluxing to the electric power of each finger electrode 311 concurrently.Welding 32 selects zinc-plated copper strips usually, can be designed to strip, is electrically connected by the finger electrode 311 on welding or conductivity bonded adhesives and cell sheet 31 surface.
Described reflector layer 5 mainly plays reflected sunlight, solar cell device 3 as shown in Figure 2 comprises multiple spaced, cell sheet 31 of being arranged side by side, the arrangement in matrix of multiple cell sheet 31, gap 33 is left between cell sheet 31, pass for welding 32, described reflector layer 5 at least covers the gap between cell sheet 31.So, as shown in Figure 3 (for the purpose of removing, this accompanying drawing omits welding), when sunlight 6 is irradiated to after on described reflector layer 5 through transparency carrier 1, upper sealant 2, reflect through reflector layer 5, reflect through transparency carrier 1 and upper sealant 2 contact interface, final arrival cell sheet 3 surface is also absorbed by monomer cell piece 3, thus improves the generating efficiency of solar module 100 again.Natch, as shown in Figure 1, described reflector layer 5 also can all standing solar cell device bottom section.
Because solar module 100 mainly utilizes sunlight to carry out opto-electronic conversion, in order to improve the reflection efficiency of reflector layer 5 pairs of sunlights, described reflector layer 5 is set to Chinese white layer, so can reduce the absorption to visible ray.
Preferably, the thickness of described Chinese white layer is more than 18 μm less than 25 μm.During lower than 18 μm, the reflectivity in visible region declines to some extent; During higher than 25 μm, the reflectivity in visible region promotes limited, can increase the thickness of solar module 100 on the contrary, therefore not recommend.
As a kind of execution mode of white Reflection layer 5 described in the utility model, by lower seal layer surface-coated one deck Chinese white layer, the existing known Chinese whites such as TiO2 or ZnO2 particle can be selected.
Preferably, the grain diameter of described Chinese white layer is more than 0.5 μm less than 1.5 μm.If the grain diameter of Chinese white layer is in above-mentioned scope, then this Chinese white layer is except the overseas also reflect near IR line expeditiously in visible region, thus more can significantly improve the generating efficiency of solar module 100.
As other Alternate embodiments of white Reflection layer 5 described in the utility model, also by lower seal layer surface mount one deck White-opalescent adhesive tape.
The foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacements, improvement etc., all should be included within scope that the utility model protects.
