Abstract
The utility model discloses a white ethylene-vinyl acetate copolymer (EVA) and glass fiber cloth compounded glue film for packaging solar cells. The glue film comprises a white EVA glue film layer and a high-transparency glass fiber cloth layer compounded on the white EVA glue film layer, wherein the glass fiber cloth has relatively high melting temperature, and white EVA does not flow when packaged and solidified, so that a smooth white reflective surface is guaranteed during packaging and solidifying, and simultaneously, the white EVA does not pollute cell pieces.
Description
Technical field
The utility model relates to the solar cell package equipment technical field, is specifically related to a kind of packaging adhesive film of used for solar batteries
Background technology
The stacked package of the common packaged type of
solar energy list (many) crystal silicon assembly: glass-EVA (ethylene-vinyl acetate copolymer)-list (many) crystal silicon battery sheet-EVA-backboard or glass; For increasing the light effect that receives of battery sheet, packaged glass and battery sheet have all done corresponding printing opacity and anti-reflection is handled.In order further to improve the sunshine utilization rate, the EVA encapsulating material has also been done corresponding improvement.EVA near glass requires light transmittance to want high, and cell back face EVA requires reflecting effect to get well.EVA chemicals Chinese: ethylene-vinyl acetate copolymer chemicals English name: ethylene-vinyl acetate copolymer is English to be called for short: EVA technical specification coding: 1314 CAS No.:24937-78-8 molecular formula: (C2H4) x. (C4H6O2) y molecular weight: 2000 (on average).
are generally increases EVA glued membrane reflecting effect; Add inorganic filler (like titanium dioxide); Make cell back face EVA packaging adhesive film present white; The sunshine that arrives back side EVA encapsulated layer effectively utilizes through repeatedly reflecting by the battery sheet, thereby to a certain degree improves solar battery assembly conversion efficiency.But the mutual fusion of meeting when white EVA and upper strata EVA package curing is difficult to guarantee smooth reflective interface, and the white EVA of part can hide at battery sheet edge simultaneously, and decremental component efficient might cause the assembly damage simultaneously
Summary of the invention
to above problem, the utility model provides a kind of can guarantee smooth white reflection face at package curing, and white EVA can not pollute the white EVA and the glass fabric composite solar battery packaging adhesive film of battery sheet simultaneously.
The purpose of
the utility model realizes through following technical scheme: the utility model provides a kind of white EVA and glass fabric composite solar battery packaging adhesive film; Comprise: white EVA adhesive film with its on compound high transparent glass fiber layer of cloth, form two-layer compound film structure.
As a kind of improvement, said white EVA layer thickness is 0.2-1 mm;
are further again, and said high transparent glass cloth layer thickness is 0.02-0.3 mm, and said white EVA layer and high transparent glass fiber layer of cloth are compound through the heating fashion of extrusion.
White EVA of
the utility model and glass fabric composite solar battery packaging adhesive film are with white EVA and glass fabric composite solar battery packaging adhesive film; Wherein glass fibre is furnished with higher relatively melt temperature; Can keep solid-state during package curing does not flow; Therefore can guarantee smooth white reflection face at package curing, white EVA can not pollute the battery sheet simultaneously.

The specific embodiment
, are further elaborated to the utility model below in conjunction with accompanying drawing and embodiment for purpose, technical scheme and the advantage that makes the utility model is clearer.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
see also Fig. 1 to Fig. 2; The utility model provides a kind of white EVA and glass fabric composite solar battery packaging adhesive film; Comprise: white EVA adhesive film 1 with its on compound high transparent glass fiber layer of cloth 2, form two-layer compound film structure.
Said white EVA layer 1 thickness is 0.2-1 mm;
said high transparent glass fiber layer of cloth 2 thickness are 0.02-0.3 mm, and said white EVA layer and high transparent glass fiber layer of cloth are compound through the heating fashion of extrusion.
White EVA layer 1 of
the utility model and glass fibre layer of cloth 2 composite solar battery packaging adhesive films are with white EVA layer 1 and glass fibre layer of cloth 2 composite solar battery packaging adhesive films; Wherein glass fibre layer of cloth 2 has higher relatively melt temperature; Can keep solid-state during package curing does not flow; Therefore can guarantee smooth white reflection face at package curing, white EVA can not pollute the battery sheet simultaneously.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the utility model
