Technical field
The utility model relates to a kind of solar cell backboard.
Background technology
Solar module directly is exposed in the atmosphere in use, stand the erosion of variations in temperature, ultraviolet irradiation and steam.As not resisting Effect of Environmental, its opto-electronic conversion performance is easy to decay, lose practical value, thereby the research of solar cell package material is very important, is subjected to people's attention.The purpose that strengthen weatherability for reaching, intercepts ultraviolet ray, steam, generally adopt two EVA glued membranes that solar cell (silicon chip) is wrapped up at present, and and upper strata glass, back veneer material hot pressing together, the EVA fusion is cooled off again, several layer materials are bonded as one, constitute the technology of solar panel, backboard wherein is made up of weathering layer and base material usually.This solar cell backboard exists that the barriering effect to steam is general, the low shortcoming of bonding strength between weathering layer and the encapsulating material EVA.
Summary of the invention
The technical problems to be solved in the utility model is: overcome above-mentioned prior art defective, a kind of solar cell backboard that does not influence function of use, barrier property height, energy and the fine combination of solar cell package material is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of solar cell backboard, it comprises base material and Nai Hou layer, after the improvement, has at least a side to be provided with weathering layer in the both sides of base material, in addition, also is provided with Obstruct membrane in a side of base material.
Above-mentioned solar cell backboard, described Obstruct membrane are a kind of or its combination in film, aluminizer or the metal aluminum foil.
Above-mentioned solar cell backboard, a side of described backboard is provided with adhesive linkage, and described adhesive linkage is a kind of in polyvinyl acetate layer, polyvinyl butyral resin layer or the olefin polymer layer.
Above-mentioned solar cell backboard, the thickness of described Obstruct membrane are 2～250 microns; The thickness of adhesive linkage is 5～300 microns; The thickness of weathering layer is 20～50 microns.
The base material that uses in the utility model can be PETG (PET) resin, poly-single or multiple lift film to formations such as (ethylene naphthalate) (PEN) resins, base material can be transparent, can also be white, black or other colors.Take all factors into consideration from aspects such as thermal endurance, electrical insulating property and prices, first-selected base material is PETG (PET) film.
For improving the weatherability of backboard, the utility model has at least a side to be provided with weathering layer in the both sides at base material, and its thickness is 20～50 microns.
Obstruct membrane can be a kind of in film, aluminizer or the metal aluminum foil or its combination, the common film that has method such as vacuum evaporation of utilizing to make behind the thin-layer silicon oxidation film that is coated with on base material (PET, the nylon etc.) surface about thick 10nm; Be coated with the aluminizer of metallic aluminium at substrate surface; The metal aluminum foil of rolling process preparation etc.Obstruct membrane can be transparent also can be opaque.Can significantly reduce the steam transit dose of solar cell backboard material behind the employing Obstruct membrane, simultaneously, adopt opaque Obstruct membrane can reduce or eliminate the transformation efficiency that sees through and then improve solar module of light.For reaching better barrier property, can also adopt the combination of above different materials.Obstruct membrane can be bonded together by the method and the base material of compound stickup, and its thickness is 2～250 microns.
Can be bonding well between backboard and the solar cell package material in order to make, improve its bonding strength, the utility model is provided with adhesive linkage in a side of backboard, it can be with encapsulating material a kind of in polyvinyl acetate (EVA), polyvinyl butyral resin (PVB) or the olefin polymer of good adhesive strength to be arranged, adhesive linkage can be bonded together with other retes by the method for compound stickup or be compounded on other retes by the method for extruding curtain coating, and its thickness is 5～300 microns.
