Description

Aging-resistant EVA film adhesive for solar cell package and preparation method thereof
Technical field
The present invention relates to the solar cell package material, particularly a kind of heat-resisting oxygen and ultraviolet light and aging are used for EVA (ethylene-vinyl acetate copolymer) glued membrane of solar cell package and preparation method thereof.
Background technology
Solar cell is by means of two-layer polymer encapsulating film silicon wafer to be packaged in wherein, again and up and down protective layer material glass and TPT film bonding.At first, packaged material must be a printing opacity, and transmitance is high, could guarantee that like this solar module after the encapsulation has enough photoelectric transformation efficiencies; In addition, the packaged material bounding force must be eager to excel, and so just can better fix and protect solar cell piece; Packaged material must be a softish before cure package, was easy to change shape, could encapsulate according to the shape of solar cell like this and can not damage the battery sheet.But it must be heat cured behind the package curing, because solar components will move under the pyritous condition, if thermoplastic deformation will take place, and seriously also can gummosis, lost provide protection to solar cell.
Before this century the eighties, once tried out liquid silicone resin and polyvinyl butyral resin sheet (PVB) both at home and abroad, all because of price height, execution conditions harshness, rerum natura is bad is eliminated.The eighties begins, U.S. Jet Propulsion and Springborn laboratory, the F.J.Pern of National Renewable Energy Laboratory (NREL) etc. just begins the solar cell packaged material is studied, light transmission according to material, modulus, workability, characteristics such as price, list ethylene-vinyl acetate copolymer (EVA) and ethylene-methyl methacrylate methyl esters (EMMA) in the JPL plan, then again at the flavescence easily under abominable weather condition of EVA glued membrane, thereby the shortcoming that influences the solar cell photoelectric turnover ratio has been carried out some researchs, has succeeded in developing ageing-resistant EVA packaging adhesive film at last.Yet, in the document of abroad publishing, mainly the composition and the aging resistance of EVA glued membrane are studied, the preparation flow of EVA glued membrane is related to very few, and EVA glued membrane price height.Domesticly also EVA sun power packaging adhesive film is studied, existing finished product is sold on market, but its effect still can not satisfy the requirement of solar cell package fully, it is poor that the comparison distinct issues remain the anti-weather of glued membrane, flavescence easily, the transmittance of influence itself, thereby the photoelectric transformation efficiency of reduction solar components.In addition, if adopt that transmittance is good, light weight, PC that anti-weather-aging property is good do under the situation of upper cover plate, the bounding force of home-made EVA glued membrane and PC does not just reach requirement at present, comes unstuck easily.
Summary of the invention
The objective of the invention is to deficiency, the preparation method of a kind of heat-resisting oxygen, the aging EVA film adhesive for solar cell package of ultraviolet resistance is provided at the weathering resistance of used for solar batteries EVA glued membrane in the prior art.
