Description
?
Technical field
The present invention relates to a kind of EVA encapsulating film, be specifically related to a kind of EVA packaging adhesive film that improves solar module spectrum efficiency of conversion.
Background technology
Sun power is a kind of green non-pollution and the inexhaustible energy; Relative other energy; Sun power for most areas on the earth have existence ubiquity, can take on the spot, thereby at last decade, solar energy industry becomes the emphasis of global various countries development.Mainly be to convert thereof into electric energy at present, and then it is used as other purposes, like street lamp, refrigerator, electromobile etc. through solar panel.
Solar cell generally is used for more abominable outdoor of environment, therefore need it be protected use.Sheet glass (header board) at present commonly used, packaging adhesive film and backboard encapsulate it.Wherein the effect of glued membrane is that header board and backboard are coupled together, and the encapsulation solar module.
And use maximum packaging adhesive films is the EVA glued membrane, generally is to adopt two identical EVA glued membranes that solar cell device is clipped in the middle.This glued membrane is crosslinked in the process of lamination of solar battery components, and sheet glass (header board) and back veneer material are coupled together, and simultaneously solar cell device is encapsulated.Receive the influence of sheet glass self transmittance (92%); The transmittance that improves the EVA glued membrane can not obviously increase and shines sunshine on the battery sheet; And the transmittance that improves the EVA glued membrane must select the higher EVA raw material of VA content, and VA content is high more, and the synthetic technology difficulty is big more; Its cost is also high more, so improve not too high practical application meaning of assembly efficiency of conversion in this way.
Present numerous EVA packaging adhesive film manufacturer has all released high-transparency EVA packaging adhesive film; This glued membrane mainly is through the adjustment formula system; Make no longer absorbing ultraviolet light of glued membrane, this part UV-light directly sees through glued membrane and is improved its photoelectric transformation efficiency by the absorption of battery sheet.Battery sheet response curve (Fig. 1) shows that the quantum yield of ultraviolet region adds power loss less than 60%, and in fact this part UV-light that sees through glued membrane can not obviously improve the photoelectric transformation efficiency of battery sheet.And because the UV-light energy is high; The long-term irradiation assembly will cause variation, the encapsulation performance of EVA glued membrane color and structure to descend and increase backboard protection burden; Reduce the work-ing life of assembly, see that from long-term interest improving the assembly efficiency of conversion in this way is a kind of way that loses more than gain.Therefore keeping being badly in need of a kind of EVA packaging adhesive film that can improve assembly spectrum efficiency of conversion under the solar module prerequisite in work-ing life.
