Abstract
The invention discloses a low-shrinkage EVA (ethylene vinyl acetate)/PC (polycarbonate) composite adhesive film for encapsulating solar cells, which is sequentially composed of an EVA film at a top layer, a PC film at a core layer and an EVA film at a bottom layer. As the PC film at the core layer has high melting point, strength and modulus, the composite EVA/PC adhesive film has better physical mechanical properties than a common EVA adhesive film, and the shrinkage is reduced to be less than 0.5%, which is far lower than that of the existing EVA adhesive film, namely 3%; and meanwhile, the transparency and aging resistance of the composite EVA/PC adhesive film completely meet the requirements of the adhesive film for encapsulating solar cells. The layered composite EVA/PC adhesive film disclosed by the invention can improve the production efficiency of solar cells, improve the product quality, reduce the defective percentage and lower the cost.
Description
Technical field
The invention belongs to the packaging adhesive film for solar cell field, be specifically related to a kind of solar cell packaging EVA/PC compound cutan with low-shrinkage.
Background technology
Solar cell is packaged in silicon wafer between glass or polycarbonate panel and the backboard by two-layer polymeric laminate usually.The effect of packaging adhesive film is that silicon wafer is fixed, and secluding air and water vapour, keeps good light transmittance simultaneously, has good photoelectric conversion rate and long service life to guarantee the solar cell after the encapsulation.In order to guarantee in the long-term use of solar cell problems such as xanthochromia, cracking, delamination not to take place, packaging adhesive film must have the performance of the aging and light aging of good heat resistance, and and panel and backboard between enough bonding forces are arranged.Common packaging adhesive film for solar cell comprises ethylene-vinyl acetate copolymer (EVA), ethylene-methyl methacrylate methyl terpolymer (EMMA), polyvinyl butyral resin sheet (PVB), ionomer, liquid silicone resin, epoxy resin etc., factors such as comprehensive light transmission, physical and mechanical properties, ageing-resistant performance, processability and price, EVA becomes the packaging adhesive film material of the solar cell of main flow at present.
Solar cell EVA packaging adhesive film in the heat pressing process process easily shrinks.This mainly is because EVA macromolecular chain in the curtain coating forming process is orientated, and the lax result of segment takes place again when being heated.The shrinkage factor of EVA glued membrane is the index that needs strict control, because when shrinkage factor was big, shrinkage stress easily made backboard generation deformation, even makes the face glass cracking, thereby causes assembly to be scrapped.Though can be by adjusting EVA glued membrane prescription, improve processing technology, carry out the shrinkage factor that method such as annealing in process reduces the EVA packaging adhesive film,, usually cause production efficiency to reduce, energy consumption and cost increase.At present, the shrinkage factor of EVA packaging adhesive film product both domestic and external can only be accomplished about 3% (test condition is 120 ℃, 3 minutes) usually, still can not satisfy the requirement of the bigger solar cell of area fully.
Summary of the invention
The invention provides the compound EVA/PC glued membrane of a kind of used for encapsulation of solar battery stratiform, its shrinkage factor significantly reduces, the physical and mechanical properties height, and the light transmission of glued membrane and performance such as anti-aging do not reduce, and overcome the defective that prior art exists.
