Abstract

ENCAPSULANTE DE UM MÓDULO FOTOVOLTAICO, USO DO ENCAPSULANTE E MÓDULO FOTOVOLTAICO. A presente invenção se refere a um encapsulante (22) de módulo fotovoltaico (20), destinado a revestir uma célula fotovoltaica (10), compreendendo: - um copolímero etileno-acrilato de alquila, o índice de fluidez MFI do copolímero estando compreendido entre 1 g/10min e 40g/10min; - um silano, representando entre 0,1% e 0,5% do peso da composição; caracterizado pelo fato de compreender adicionalmente um agente de reticulação representando entre 0,1% e 0,5% do peso da composição e pelo fato de que o copolímero representa pelo menos 99% do peso da composição. A invenção se refere igualmente ao uso de tal encapsulante em um módulo fotovoltaico, bem como a um módulo fotovoltaico incorporando tal encapsulante.
