Abstract
The utility model discloses the EVA solar cell glued membrane of three-decker, comprise the EVA adhesive film of white EVA adhesive film, glass layer and high transmission rate, the EVA adhesive film forming white EVA adhesive film/glass layer/high transmission rate forms the film structure of three layers of compound; In this structure, glass layer mainly plays the effect of support structure, solve the problem of shrinkage in white EVA adhesive film surface cross-linking process, then by making glued membrane dorsal part and photovoltaic component back plate or backing layer glass have excellent adhesive property at glass fibre opposite side showering transparent EVA layer.
Description
Technical field
The utility model relates to a kind of EVA solar cell glued membrane of three-decker.
Background technology
The structure of existing monocrystalline silicon and polysilicon members is generally glass/EVA adhesive film (cephacoria)/cell piece/EVA adhesive film (caudacoria)/backboard.In order to improve the utilization rate of photovoltaic module to sunshine, and then improve the power output of photovoltaic module, EVA adhesive film aspect has also been made corresponding technology and has been improved, as EVA adhesive film (cephacoria) improves light transmittance, more sunshine is absorbed by cell piece, EVA adhesive film (caudacoria) forms white glued membrane raising light reflectance by adding titanium dioxide, makes, not by the sunshine that sunshine utilizes, again to reflect back and absorbed by cell piece.Mutually merge the phenomenon of flowing when white EVA adhesive film exists photovoltaic module lamination with transparent EVA glued membrane, cause reflecting surface out-of-flatness, while partial white EVA can hide cell piece surface, affect outward appearance and assembly quality.Have some film structures to solve at present problem that white EVA adhesive film affects assembly outward appearance, as used glass fibre or polypropylene non-woven fabric as separation layer, use transparent EVA/white EVA double-layer coextrusion structure, entirety is carried out to white EVA adhesive film and is cross-linked to reduce its mobility etc.But double-layer coextrusion structure exists the problem reducing reflective surface rate in these modified node method, use separation layer easily to occur the bonding problem loosely of delamination, the entirety of glued membrane is cross-linked the problem that also there is adhesive strength and decline.
Summary of the invention
For the problems referred to above, the utility model provides a kind of EVA solar cell glued membrane of three-decker.
The purpose of this utility model is realized by following technological means: a kind of EVA solar cell glued membrane of three-decker, the high transmission rate EVA adhesive film comprising glass layer, be bonded in the white EVA adhesive film of glass layer side, be bonded in glass layer opposite side.
Further, described white EVA adhesive film (1) thickness is 0.1-1.5mm.
Further, described glass layer (2) thickness is 0.1-0.3mm.
Further, EVA adhesive film (3) thickness of described high transmission rate is 0.05-0.5mm.
The utility model not only solves surface cross-linking structure and solves overflow problem; And glass layer is played a supporting role, solve the problem that in surface cross-linking process, glued membrane shrinks, the high transmission rate EVA adhesive film of showering also solves the problem of back side adhesive strength.
Accompanying drawing explanation
Fig. 1 is the side-looking direction structure schematic diagram of the EVA solar cell glued membrane of the utility model three-decker.
In figure, 1 is white EVA adhesive film, and 2 is that glass layer, 3 is for high transmission rate EVA adhesive film.
Detailed description of the invention
As shown in Figure 1, the EVA solar cell glued membrane of a kind of three-decker of the utility model, the high transmission rate EVA adhesive film 3 comprising glass layer 2, be bonded in the white EVA adhesive film 1 of glass layer side, be bonded in glass layer opposite side.Glass layer 2 mainly plays the effect of support structure, solves the problem of shrinkage in white EVA adhesive film 1 surface cross-linking process; Glass layer 2 opposite side showering high transmission rate EVA adhesive film 3 makes glued membrane dorsal part and photovoltaic component back plate or backing layer glass have excellent adhesive property.
Described white EVA adhesive film 1 thickness is 0.1-1.5mm.Say known product as this area, the white EVA adhesive film 1 in the utility model can adopt Hangzhou First Photovoltaic Material Co., Ltd. F806W product.
Described glass layer 2 thickness is 0.1-0.3mm.Say known product as this area, the glass layer 2 in the utility model can adopt the lucky one hundred sharp Environmental Protection Technology Co., Ltd JBX-YD-40 product in Dongguan.
EVA adhesive film 3 thickness of described high transmission rate is 0.05-0.5mm.Say known product as this area, the EVA adhesive film 3 of the high transmission rate in the utility model can adopt company of Hangzhou First Photovoltaic Material Co., Ltd. F406S product.
The preparation method of the EVA solar cell glued membrane of above-mentioned three-decker is as follows: glass layer 2 and the micelle of white EVA adhesive film are together passed through flower roller and rubber roll, through between roller, mediate power compound, then be cured the EVA adhesive film structure of the two-layer compound obtaining white EVA adhesive film/glass fibre by UV-crosslinked mode; Then the EVA adhesive film of high transmission rate is compound to the non-white EVA adhesive film contact side of the EVA adhesive film structure of the two-layer compound of white EVA adhesive film/glass fibre by the mode of showering, obtains the EVA solar cell glued membrane of three-decker.
Claims (4)
