Description
Technical field
The utility model is related to a kind of three-layer co-extruded photovoltaic encapsulation glued membranes of mosaic, are mainly used in solar photovoltaic assembly
Encapsulation field.
Background technology
Due to the price rapid decrease of photovoltaic Related product in recent years, the photoelectric conversion efficiency of solar cell is improved to drop
The overall cost in low power station becomes the only way that each producer's solar panel producer researches and develops selection.Traditional EVA encapsulating materials, only
It is to play the role of packaging protection, achievement is had no in terms of raising efficiency.The pure white EVA of part of the manufacturer's production, because of the titanium of addition
Itself physical property of white powder easily causes cell piece is hidden to split and cohesive force is relatively low, excessive glue to cell piece front causes entire component
It reprocesses or scraps, thus fail to quote extensively always.Then three-layer co-extruded packaging adhesive film becomes as trend in recent years, and front and back two
Face uses convention transparent EVA, prevents white EVA excessive glues；Middle layer is added into a certain proportion of toner and makes white, can effectively be increased
Add the reflectivity about 90% or more of light, the light of reflection that can be utilized by solar cell double absorption, entirety can be increased too
Positive energy component efficiency about 2% or so, plays the role of good cost efficiency.But the program is made because of the presence of in-between titanium dioxide
At the difference of middle layer and front and back laminar flow, it be easy to cause delamination and white migrates to hyaline layer and causes mutually perforation etc.
Defect has seriously affected use.
Convention transparent EVA adhesive film is to light areflexia, to the power gains of solar components without help, and simply by EVA
Film makes pure white, and will produce bad order, toner migration, the problems such as cohesive force is relatively low；
The new problem that conventional three-layer co-extruded EVA can solve the problems, such as that above-mentioned items are bad, but bring again simultaneously；Because of titanium white
It mutually perforates or migrates between the difference of physical property makes its difference of flowability that can lead to layer between layers caused by the addition of powder, very
To the phenomenon that delamination, its use and popularization are seriously affected.
Utility model content
Technical problem to be solved in the utility model is that provide a kind of mosaic for the above-mentioned prior art three-layer co-extruded
Photovoltaic encapsulation glued membrane, it can improve the electricity conversion of component, while bad without flange, peeling force decaying etc.；And layer with
Be not in mutual migration or delamination between layer.
The technical scheme in the invention for solving the above technical problem is：A kind of three-layer co-extruded photovoltaic encapsulation glue of mosaic
Film, it uses three-layer co-extruded structure, and upper layer and lower layer is transparent, and middle layer makes white；
Upper hyaline layer lower surface is provided with upper layer decorative pattern, and lower hyaline layer upper surface is provided with lower layer's decorative pattern, middle layer it is upper
Surface is provided with middle layer decorative pattern, the inserted cooperation between the decorative pattern of upper layer；During the lower surface of the middle layer is also equipped with
Interbed decorative pattern, inserted cooperation between the middle layer decorative pattern and lower layer's decorative pattern.
Upper layer decorative pattern, middle layer decorative pattern and lower layer's decorative pattern are positive tetrahedron type decorative pattern.
The upper layer decorative pattern, middle layer decorative pattern and lower layer's decorative pattern are Argyle.
Compared with prior art, the utility model has the advantage of：
The utility model is three-layer co-extruded by the use of glued membrane, and both sides are transparent, and intermediate one layer is made white, can keep original again
On the basis of performance, the power gain of lifting assembly about 2% or so；It is bad without flange, peeling force decaying etc. simultaneously.Furthermore layer with
It is inlayed using Argyle between layer, it is inconsistent because of flow rate that mutual active force so that glued membrane is reduced in lamination
The defects of migrating, perforating mutual between layers generated.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the three-layer co-extruded photovoltaic encapsulation glued membrane of mosaic of the utility model.
Wherein：
1 is upper hyaline layer, and 2 be upper layer decorative pattern, and 3 be middle layer, and 4 be middle layer decorative pattern, and 5 be lower layer's decorative pattern, 6 be under it is transparent
Layer.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
A kind of three-layer co-extruded photovoltaic encapsulation glued membrane of mosaic of the utility model, it uses three-layer co-extruded structure, upper and lower both sides
Transparent, middle layer makes white；
1 lower surface of upper hyaline layer is provided with upper layer decorative pattern 2, and lower 6 upper surface of hyaline layer is provided with lower layer's decorative pattern 5, middle layer 3
Upper surface be provided with middle layer decorative pattern 4, the inserted cooperation between upper layer decorative pattern 2；The lower surface of the middle layer 3 is also set
It is equipped with middle layer decorative pattern, inserted cooperation between the middle layer decorative pattern 4 and lower layer's decorative pattern 5.
Upper layer decorative pattern 2, middle layer decorative pattern 4 and lower layer's decorative pattern 5 are positive tetrahedron type decorative pattern, preferably Argyle.
The three-layer composite structure that decorative pattern is inlayed, middle layer make white, can improve the electricity conversion about 2% of component,
It is bad without flange, peeling force decaying etc. simultaneously.It is inlayed between layers using Argyle, mutual active force makes glue
Film reduces the defects of mutually migrating, perforate between layers of the inconsistent generation because of flow rate in lamination.
In addition to the implementation, the utility model further includes having other embodiment, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection domain of the utility model claims.
