Abstract
The invention relates to an adhesive film for component packaging and a back panel, in particular to an EVA (Ethylene Vinyl Acetate) adhesive film for packaging a solar component and a back panel of a solar component. The EVA adhesive film for packaging the solar component is formed by convergence of an ethene-vinyl acetate copolymer and a crosslinked curing agent, and a drying agent filler is mixed in the EVA adhesive film. The back panel of the solar component comprises an EVA adhesive film with a drying agent filler, a middle support and an outer protective film, wherein the middle support is positioned between the EVA adhesive film and the outer protective film and integrally bonded with the EVA adhesive film and the outer protective film. The invention has the benefits that the EVA adhesive film for packaging the solar component can effectively prevent water vapor in air from penetrating and entering the component; the back panel of the solar component, including the EVA adhesive film, not only can effectively prevent water vapor from entering but also has a favorable bonding capability with the back side of a cell, so that the step of paving an EVA packaging adhesive film between the back panel and the cell in the packaging and laminating processes of the solar component is omitted, and the component preparation process is simplified.
Description
Technical field
The present invention relates to component package with glued membrane and backboard, particularly solar components packaging EVA adhesive film and backboard.
Background technology
In one of main appeal point of the photovoltaic customer complaint of greater coasting area: the black line of assembly or washmarking problem.The reason that black line or washmarking produce is: because greater coasting area, be full of the steam that contains salt in the environment that assembly uses, electrochemical reaction occurs this silver slurry for solar cell surface provides good electrolyte environment, this will cause and accelerate the silver slurry electrochemical oxidation reactions occurs, form silver suboxide, thereby with the naked eye can obviously observe black line or washmarking phenomenon at assembly surface.This not only can affect the overall appearance of assembly, also can increase the series resistance of assembly, affects the power generation capacity of assembly.So it is very urgent to solve black line or the washmarking problem of assembly.
The research or the patent that solve component internal steam problem also have much.Set out such as the optimization angle to packaged material, select the backboard of low water vapor transmittance, the packaging adhesive film of low water vapor transmittance etc.Patent CN101345267A discloses a kind of method of encapsulation optimization of amorphous silicon film battery, solves the work reliability problem of film battery assembly by be encapsulated into siccative in assembly.
Summary of the invention
Technical problem to be solved by this invention is: a kind of solar components packaging EVA adhesive film and backboard are provided, avoid reducing entering of water in air vapour, can suppress assembly and black line or washmarking phenomenon occur.
The technical solution adopted for the present invention to solve the technical problems is: a kind of solar components packaging EVA adhesive film, be polymerized by multipolymer and the crosslinking and curing agent of ethene-vinyl acetate, and in the EVA glued membrane, also be mixed with the siccative filler.
The VA content of the multipolymer of the ethene-vinyl acetate in the EVA glued membrane is 20mol% ~ 35mol%, and the content of siccative filler is 1wt% ~ 10wt%.
For increasing ageing resistance and the cohesive force of EVA glued membrane, in the EVA glued membrane, also be mixed with antiaging agent and tackifier.
The siccative filler is porous silica, calcium oxide, nano-class molecular sieve or gac.
A kind of solar components backboard comprises EVA glued membrane, intermediate support and the outer protective membrane of hybrid desiccant filler, and middle support and is bonded into one with EVA glued membrane and outer protective membrane between EVA glued membrane and outer protective membrane.
Intermediate support is the PET material.
Outer protective membrane is fluoropolymer membrane.
Fluoropolymer membrane is fluorinated ethylene propylene, polyvinylidene difluoride (PVDF), poly(vinylidene fluoride) or THV.
The invention has the beneficial effects as follows: this solar components packaging EVA adhesive film can stop airborne steam to see through effectively.
The solar components backboard that comprises this EVA glued membrane effectively encapsulates ability except having traditional backboard, and backboard is inboard and there is good viscosifying power at the cell piece back, can save the laying step at the EVA packaging adhesive film of traditional crystal silicon battery assembly between encapsulation lamination process mesonotal shield and cell piece, the simplified assembly preparation process.And because the existence of the inboard siccative filler of backboard is compared with traditional backboard, have better water vapor absorption and obstructing capacity, the black line phenomenon can arrive effectively containment, and this will improve the assembly outward appearance greatly, improve the generated energy of assembly, reduce cost of electricity-generating.
