Glued membrane and lower floor's packaging adhesive film a generally only Rotating fields).
But, in actual lamination process, lower floor UV barrier packaging adhesive films are possible to that cell piece surface can be spilt over, so that shadow
Generating efficiency is rung；And, the UV auxiliary agents of lower floor's packaging adhesive film can diffuse to upper strata packaging plastic in component in actual use
In film, so as to greatly reduce the generating efficiency of component.In addition, some solar cells employ special solder resist or electricity
Pond piece, they are bad with UV absorbent compatibility so that UV absorbents can be separated out and shape at cell piece, busbar, the welding back side
Yellowly color spot, so as to cause component facade bad.
The content of the invention
The utility model purpose is to provide a kind of UV barriers envelope used for solar batteries to overcome the deficiencies in the prior art
Fill glued membrane.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of UV barriers encapsulation used for solar batteries
Glued membrane, it includes at least one layer of UV barrier layers of high permeable layers and formation in the high permeable layers any surface.
Optimally, it is made up of high permeable layers and the UV barrier layers formed in the high permeable layers any surface.
Optimally, the thickness of the high permeable layers is 50~400 μm.
Optimally, the thickness of the UV barrier layers is 100~600 μm.
Optimally, it is that the high permeable layers and the UV barrier layers coextrusion mold or film layer are suppressed.
A further object of the present invention is to provide a kind of solar cell module using above-mentioned packaging adhesive film, it include by
Backsheet layer, lower floor's packaging adhesive film, cell piece, upper strata packaging adhesive film and the glassy layer being cascading upwards down, the lower floor
Packaging adhesive film is above-mentioned UV used for solar batteries barrier packaging adhesive films, and the high permeable layers are in contact with the cell piece.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：The utility model
UV used for solar batteries obstructs packaging adhesive film, by forming at least one layer of UV barrier layers in any surface of high permeable layers, so may be used
To avoid the UV auxiliary agents in UV barrier layers from diffusing out, it is to avoid the reduction of solar cell power generation efficiency, and it can avoid
Solder resist or cell piece and UV absorbents it is incompatible caused by xanthochromia；And high permeable layers will not be produced with upper strata packaging adhesive film
Life influences each other, and cell piece surface is spilt over even if it also will not influence generating efficiency as conventional glued membrane.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model UV used for solar batteries obstructs packaging adhesive film.
Embodiment
The utility model is further described below in conjunction with embodiment.
UV used for solar batteries barrier packaging adhesive films as shown in Figure 1, it includes high permeable layers 1 and at least one layer UV barrier layers
2。
Wherein, the matrix resin of high permeable layers 1 can be EVA, POE, polyvinyl butyral resin (PVB), ionomer, poly- ammonia
Ester, silica gel or epoxy resin, and (addition of above-mentioned auxiliary agent is containing the auxiliary agent such as appropriate crosslinking agent, crosslinking coagent, coupling agent
Conventional mass content), its thickness is usually 50~400 μm.And at least one layer of UV barrier layers 2, they are formed in height
On any surface of permeable layers 1 (on i.e. a certain surface).In the present embodiment, packaging adhesive film is by high permeable layers 1 and is formed for UV barriers
Constituted in the UV barrier layers 2 of the high any surface of permeable layers 1, so can be with cost-effective and simplified manufacture craft.The base of UV barrier layers 2
Body resin can be EVA, POE, polyvinyl butyral resin (PVB), ionomer, polyurethane, silica gel or epoxy resin, and thickness is usual
For 100~600 μm；It can also containing the auxiliary agent such as appropriate crosslinking agent, crosslinking coagent, coupling agent, its matrix resin preferably with
The matrix resin of high permeable layers 1 is consistent；Unlike, UV barrier layers 2 contain UV absorbers, the purple that high permeable layers 1 do not have
The UV such as outer light stabilizer auxiliary agents (addition of above-mentioned auxiliary agent is conventional mass content), to ensure that UV light can not pass through,
So as to avoid influence of the UV light to solar cell module back veneer, so as to improve the life-span of battery component.In the present embodiment,
