Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.Elaborate a lot of detail in the following description so that fully understanding this utility model.But this utility model can be implemented to be much different from alternate manner described here, those skilled in the art can do similar improvement in the case of this utility model intension, and therefore this utility model is not limited by following public specific embodiment.
Below in conjunction with the accompanying drawings, the better embodiment of this utility model solar module is described in detail.
With reference to Fig. 1, the utility model proposes a kind of solar module 100, including backboard 110, cover plate 120, multiple solar battery sheets 130 of being pressed together between backboard 110 and cover plate 120.Wherein, the sensitive surface of solar battery sheet 130 is relative with cover plate 120, and the shady face of solar battery sheet 130 is relative with backboard 110.
It is provided with the first transparent encapsulation material 140 between cover plate 120 and solar battery sheet 130, cover plate 120 is packaged as a whole with solar battery sheet 130.First transparent encapsulation material 140 is the EVA (ethylene-vinyl acetate copolymer, ethylene-vinyl acetate copolymer) of high transmission rate.
Additionally, cover plate 120 is additionally provided with the first antireflective coating 122 on the surface of solar battery sheet 130, to increase the transmitance of light.The material that cover plate 120 can use glass etc. to have preferable light transmittance prepares.
It is provided with the second transparent encapsulation material 150 between backboard 110 and solar battery sheet 130, cover plate 120 is packaged as a whole with solar battery sheet 130.Second transparent encapsulation material 150 is the EVA of high transmission rate.
It is additionally provided with the second antireflective coating (non-label) on the sensitive surface of solar battery sheet 130, to increase the transmitance of light, improves the assimilation effect of light.
Ginseng Fig. 1, the gap 160 between each solar battery sheet 130 is provided with white reflection film 170.Vacant position around solar battery sheet arranges this white reflection film 170 equally.Incident illumination, after gap 160 or vacant position are injected, is reflected back cover plate 120 effectively by white reflection film 170, thus by the optics Behavior-Based control in assembly in the sensitive surface side of cell piece.Gap 160 between each solar battery sheet 130 and the vacant position around solar battery sheet, be typically commonly called as being left white, and particular location refers to shown in Fig. 4.
White reflection film 170 is preferably used white EVA adhesive tape, and its material is identical with the first transparent encapsulation material 140 main component, and the cohesive of such assembly entirety is preferable.The main component of white EVA adhesive tape may be such that EVA resin 76%-96%, and wherein vinyl acetate content is less than 5%；Ultraviolet absorber 0.05-0.2%, antioxidant 0.03-.0.2%；Silane coupler 0.3～3%；Reflective filler 1～20%, above for weight ratio.White reflection film 170 can also is that white rubber thin film, white ETFE (ethylene-tetra-fluoro-ethylene, ethylene-tetrafluoroethylene copolymer) thin film.
As it is shown in figure 1, white reflection film 170 can be attached on the shady face of solar battery sheet 130, with by the gap 160 between solar battery sheet 130, and the vacant position around solar battery sheet is covered.
Further, the side surface that white reflection film 170 is relative with cover plate 120, it is set to concordant with the sensitive surface of solar battery sheet 130.Thus, white reflection film 170 will gap 160 between solar battery sheet 130 and being covered at the vacant position around solar battery sheet at sensitive surface.When incident illumination is injected from above-mentioned gap 160, vacant position, these light are just reflected back at sensitive surface by white reflection film 170, shorten the light path of these light, thus reduce the loss of these light.
Ginseng Fig. 2, the side surface that white reflection film 170 is relative with cover plate 120 is additionally provided with to increase the diffusion layer 172 of scattering of light.Diffusion layer 172 can increase the light scattering to surrounding, makes more light be absorbed by solar battery sheet, and then improves electric current density.
Ginseng Fig. 2, the column structure that surface Formation cross-section is triangle of diffusion layer 172, light, after left side is irradiated, is spread when penetrating from right side, it is possible to have the different parts of more light directive cell piece.The surface of diffusion layer 172 is not limited to form above-mentioned column structure, as long as the disperse of light can be increased.For example, it is possible to the surface of the structure processing diffusion layer 172 of reference crystal.Nanotechnology can be used to be processed to form diffusion layer 172.
The surface that cover plate 120 is relative with solar battery sheet 130 is additionally provided with catoptric arrangement 124, to increase the reflecting effect to light, enables more light to be reflected back the sensitive surface of solar battery sheet 130.Catoptric arrangement 124 is the concaveconvex structure using embossed technology to be formed, as shown in Figure 3.
It addition, cover plate 120 can be common cover plate, such as common glass plate.That is, cover plate 120 can be not provided with catoptric arrangement 124.
Due to white reflection film 170 by the optics Behavior-Based control of assembly in the sensitive surface side of solar battery sheet 130, therefore, this utility model can be completely without arranging backboard 110.When still arranging backboard 110, owing to need not reflect by backboard 110, backboard 110 can be common backboard, without arranging reflective structure on the surface of backboard 110.
The preparation process of solar module 100 is briefly described below.
Ginseng Fig. 4, simultaneously auxiliary reference Fig. 5, after preparing the cell piece of interconnection, the gap 160 white reflection film 170 being bonded on the shady face of solar battery sheet 130 and covering between solar battery sheet 130, and cover the vacant position around solar battery sheet 130.
Ginseng Fig. 5, lamination flow process approximately as:
Sequentially, backboard the 110, second transparent encapsulation material 150 (EVA), solar battery sheet the 130, first transparent encapsulation material 140 (EVA), cover plate 120 are set gradually.
Then it is laminated after each layer being alignd by the order laid.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
