Description
Technical field
The application is related to field of photovoltaic technology, more particularly to a kind of photovoltaic component encapsulating glued membrane.
Background technology
EVA (ethylene-vinyl acetate copolymer) is a kind of thermoplastic macromolecule material, because cost is low, convenient formation, light
Prominent performance, mechanical property and excellent electrical property etc. are learned, is widely used as solar cell package material.
In the prior art, in order to improve the efficiency of solar cell, often by being set on solar cell backboard
White EVA is reduced to encapsulate and lost, so as to lift the power output of solar cell to increase reflection.
But the white EVA used in the prior art, easily produce positive excessive glue, fold.Meanwhile white EVA with it is described
Peel strength between solar cell backboard is relatively low, easily comes off, and can influence the stability of solar cell power output, influences
The normal work of solar cell.
At least there are the following problems in the prior art：The white EVA used in the prior art, easily produce positive excessive glue,
Peel strength between fold, with solar cell backboard is relatively low, easily comes off, and the stability of solar cell power output is produced
It is raw to influence.
Utility model content
The purpose of the embodiment of the present application is to provide a kind of photovoltaic component encapsulating glued membrane, to improve packaging adhesive film and solar-electricity
The peel strength of pond plate, positive excessive glue, fold are prevented, while reduce cost.
The embodiment of the present application provides what a kind of photovoltaic component encapsulating glued membrane was realized in：
A kind of photovoltaic component encapsulating glued membrane, the film include：
Intermediate layer, it is arranged to the white macromolecule membrane with the first preset thickness；
Upper strata, the transparent EVA with the second preset thickness is arranged to, is bonded on the upper surface in the intermediate layer；
Lower floor, the transparent EVA with the 3rd preset thickness is arranged to, is bonded on the lower surface in the intermediate layer.
In preferred embodiment, the lower floor is bonded on the solar cell backboard.
In preferred embodiment, first preset thickness, second preset thickness, the 3rd preset thickness phase are in addition
With more than or equal to 300 microns and less than or equal to 600 microns.
A kind of photovoltaic component encapsulating glued membrane provided using the embodiment of the present application, passes through the following table in white macromolecule membrane
Layer of transparent EVA is bonded on face, because the peel strength of transparent EVA and solar cell backboard is higher, eva film can be increased
Reliability.By on the upper surface of white macromolecule membrane be bonded layer of transparent EVA, can effectively prevent positive excessive glue,
Fold.While stating effect in realization, the function of eva film increase reflection is not interfered with, moreover, EVA described herein
Film cost is less than the white EVA of same thickness, using eva film described herein, can reduce cost.
Brief description of the drawings
