| description | A composition and method for encapsulating a photovoltaic device which minimizes discoloration of the encapsulant. The composition includes an ethylene-vinyl-acetate encapsulant, a curing agent, an optional ultraviolet light stabilizer, and/or an optional antioxidant. The curing agent is preferably 1,1-di-(t-butylperoxy)-3,3,5-trimethylcyclohexane; the ultraviolet light stabilizer is bis-(N-octyloxy-tetramethyl)piperidinyl sebacate and the antioxidant is selected from the group of tris(2,4-di-tert-butylphenyl) phosphite, tetrakis methylene (3,5-di-tert-butyl-4-hydroxyhydrocinnamate)methane, octadecyl 3,5-di-tert-butyl-4-hydroxyhydrocinnamate, and 2,2'-ethylidene bis(4,6-di-t-butylphenyl) fluorophosphonite. The composition is applied to a solar cell then cured. The cured product contains a minimal concentration of curing-generated chromophores and resists UV-induced degradation.
Cette invention se rapporte à une composition et à un procédé d'encapsulation de composants photovoltaïques permettant de réduire au minimum la décoloration de l'agent d'encapsulation. Cette composition contient un agent d'encapsulation à base d'éthylène et d'acétate de vinyle, un agent durcissant, un stabilisant anti-UV optionnel et/ou un anti-oxydant optionnel. L'agent durcissant est de préférence du 1,1-di-(t-butylperoxy)-3,3,5-triméthylcyclohexane; le stabilisant anti-UV est du bis-(N-octyloxy-tétraméthyl)pipéridinyl-sébacate et l'anti-oxydant est choisi dans le groupe tri(2,4-di-tert-butylphényl)phosphite, tétrakis méthylène (3,5-di-tert-butyl-4-hydroxyhydrocinnamate)méthane, octadécyl 3,5-di-tert-butyl-4-hydroxyhydrocinnamate et 2,2'-éthylidène bis(4,6-di-t-butylphényl) fluorophosphonite. Cette composition est appliquée à une cellule solaire, ensuite durcie. Le produit durci contient une concentration minimum de chromophores générés lors de l'opération de durcissement et il résiste à la dégradation induite par les UV. |
