Modified EVA Encapsulant Formulations for Low Temperature Processing: Preprint

摘要: Presented at the 2001 NCPV Program Review Meeting: We have developed several new ethylene-vinyl acetate (EVA) formulations modified on basis of NREL patented EVA [1]. The can be cured to a desired gel content {approx}80% in ambient temperatures 20-30 C lower than typical conditions vacuum (i.e. {approx}150 C). Glass/glass laminates showed transmittance spectra that are essentially same as 15295P visible and NIR regions but higher UV region. Results fluorescence analysis ambient-processed concentrations curing-generated {alpha},{beta}-unsaturated carbonyl chromophores, which responsible for induced discoloration photodegradation, were considerably 15295P, therefore suggesting better photochemical stability formulations.
