A kind of solar components
The utility model relates to a kind of battery component, relates in particular to a kind of solar components.
Solar cell is semiconductor device (physical battery), and it can be directly is electric energy with the transform light energy of sunlight.Owing to need not water, oil, vapour, fuel during its work, the characteristics that only need to have luminous energy just can generate electricity can be rated as cleaning in the present age, free of contamination regenerative resource, and installation and maintenance are simple, and long service life is the outstanding person in the new forms of energy.In the last few years, the popularization, particularly photovoltaic plant that are applied in the whole world of solar energy obtained more and more general application.
Solar module adopts popular package assembly at present; Toughened glass--EVA(ethene-acetate ethylene copolymer) the compound fluoroplastics film of--series-connected solar cells--EVA--TPT(weatherability) laminate packaging forms.In this encapsulation owing to adopted toughened glass, so exist frangible, from great defective; Because backboard adopts TPT film and cell piece series connection, determines that again the solar components lead-out wire must be in the limitation at two.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
The utility model content
The purpose of this utility model is for original solar module is frangible on the market, weight is large, the circumscribed shortcoming of lead-out wire, and a kind of ultralight, portable, easy installation, the long solar components of physical life are provided.
The technical solution adopted in the utility model is:
A kind of solar components, this solar components successively stacked package have PVC layer, EVA adhesive film, solar battery sheet, EVA adhesive film and TPE hyaline membrane.
Described TPE hyaline membrane adopts the compound fluoroplastics membrane material of double-deck weatherability to make.
EVA adhesive film between described solar battery sheet and the TPE hyaline membrane is two-layer.
Described solar battery sheet is the solar battery sheet that interconnecting strip connects.
The utility model has the advantages that: adopted double-deck EVA adhesive film, made component lamination technique more stable; Adopt the TPE hyaline membrane, to compare outer light more attractive in appearance with popular assembly, and light transmittance is high simultaneously; Adopt the PVC layer to replace glass, overcome the defective that popular assembly is frangible, weight is large, make this product weight ultralight, easy to carry, the PVC layer provides effective support to solar module, makes the structure of solar components more firm, and application is more extensive.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, PVC layer, 2, the EVA adhesive film, 3, solar battery sheet, 4, the TPE hyaline membrane.
As shown in Figure 1, a kind of solar components of the present utility model, this solar components successively stacked package has PVC layer 1, EVA adhesive film 2, solar battery sheet 3, two-layer EVA adhesive film 2 and TPE hyaline membrane 4, described TPE hyaline membrane 4 adopts the compound fluoroplastics membrane material of double-deck weatherability to make, the solar battery sheet 3 that described solar battery sheet 3 connects for interconnecting strip, adopted double-deck EVA adhesive film 2, made component lamination technique more stable; Adopt TPE hyaline membrane 4, to compare outer light more attractive in appearance with popular assembly, and light transmittance is high simultaneously; Adopt PVC layer 1 to replace glass, overcome the defective that popular assembly is frangible, weight is large, make this product weight ultralight, easy to carry, 1 pair of solar module of PVC layer provides effective support, makes the structure of solar components more firm, and application is more extensive.
