Abstract
The present invention relates to eva film of a kind of solar cell package and preparation method thereof, composed of the following components according to mass percent: ethylene-vinyl acetate base co-polymer 80 ~ 90%, peroxidized t-butyl perbenzoate 1 ~ 2%, 3-aminopropyl trimethoxysilane 0.5 ~ 1%, three (nonyl phenyl) phosphorous acid ester 0.05 ~ 2%, tert-butyl hydroperoxide 2-ethylhexyl carbonate 0.5 ~ 1%, 3,5-di-tert-butyl-4-hydroxybenzoic acid cetyl ester 1 ~ 3%, surplus is organic solvent.The eva film of this solar cell package, high volume specific resistance, high permeability, low xanthate ratio can be had, improve the photoelectric conversion rate of series of cells simultaneously, and a kind of technique is simple, easy to operate, and the preparation method of the eva film of the solar cell package that good dispersity, binding property are good, stability is high.
Description
Technical field
The present invention relates to eva film of a kind of solar cell package and preparation method thereof, belong to technical field of organic chemistry.
Background technology
Under the situation of global warming, human ecological environment deterioration, conventional energy resources shortage, the strategy of sustainable development is accepted by countries in the world.Sun power has the advantages such as spatter property, security, resource abundance, is 21st century one of most important new forms of energy, is subject to attention and the support of national governments.Photovoltaic market sharply expanded in recent years, and supply falls short of demand for photovoltaic products.
Along with the development of photovoltaic module science and technology and some problems of discovery in using, namely assembly is for a long time under action of high voltage, make to there is leakage current between glass, packaged material, a large amount of accumulation is on cell piece surface, the passivation effect of battery surface is worsened, cause FF, Jsc, Voc to reduce, make assembly property lower than standard.In 2010, NREL and Solon confirmed the p-type crystal-silicon battery slice no matter which kind of technology assembly adopts, and assembly has the risk of PID under negative bias.In view of the raising that development and the photovoltaic plant of current photovoltaic industry science and technology require photovoltaic module, photovoltaic module manufacturing enterprise all adds tight requirement to product quality, using PID test passes as the qualified additional index of photovoltaic module.About causing PID to test the reason do not met the demands, now more consistent understanding is as follows: external cause: in high temperature, humidity and the serious corrosion of the photovoltaic module that causes due to photovoltaic DC-to-AC converter array ground mode and decline; Internal cause: system, assembly and cell piece three aspects all can cause PID phenomenon.
In assembly, the packaged material adopting performance good is one of approach preventing PID from occurring, and wherein the volume specific resistance of packaged material (being generally EVA adhesive film) wishes to be not less than 1 × 10
15Ω cm.External photovoltaic module is produced, and strict for various raw-material control, do not use defective starting material, therefore the PID of photovoltaic module can meet the demands substantially.Wherein EVA glue film for photovoltaic component is without particular requirement, and volume specific resistance is 1 × 10
14the EVA adhesive film of Ω cm can meet the demands, but the volume specific resistance of external a lot of EVA adhesive film all reaches 1 × 10
15Ω cm is even higher.According to the situation of domestic relative photo photovoltaic assembly manufacturing enterprise reflection, the photovoltaic module adopting Monocrystalline silicon cell piece to produce, adopts existing EVA adhesive film can meet PID test request.Adopt the photovoltaic module that polycrystalline silicon battery plate is produced, if when polycrystal silicon cell tablet quality is good, adopt existing EVA adhesive film also can meet PID test request, according to polycrystalline silicon battery plate more of poor quality, adopt existing EVA adhesive film can not meet PID test request, after PID test, the generated output of photovoltaic module reduces a lot, substantially exceeds the limit value of 5%.Make a general survey of domestic existing EVA adhesive film, volume specific resistance is all lower.
Summary of the invention
The technical problem that the present invention solves is: the eva film proposing a kind of solar cell package, high volume specific resistance, high permeability, low xanthate ratio can be had, improve the photoelectric conversion rate of series of cells simultaneously, and a kind of technique is simple, easy to operate, and the preparation method of the eva film of the solar cell package that good dispersity, binding property are good, stability is high.
The technical scheme proposed to solve one of them technical problem above-mentioned is: ethylene-vinyl acetate base co-polymer 80 ~ 90%, peroxidized t-butyl perbenzoate 1 ~ 2%, 3-aminopropyl trimethoxysilane 0.5 ~ 1%, three (nonyl phenyl) phosphorous acid ester 0.05 ~ 2%, tert-butyl hydroperoxide 2-ethylhexyl carbonate 0.5 ~ 1%, 3,5-di-tert-butyl-4-hydroxybenzoic acid cetyl ester 1 ~ 3%, surplus is organic solvent;
In described ethylene-vinyl acetate base co-polymer, the massfraction of vinyl acetate is 29.4 ~ 29.7%;
