Abstract

A method for forming photovoltaic cell module laminates wherein the cells are sealed in a crosslinked polymer between a solid superstrate and a solid substrate wherein the polymer is formed from ethylene/vinylacetate copolymer having dispersed therein at least one peroxide initiator to crosslink the polymer and at least one organosilane primer to promote bonding of the ethylene/vinylacetate to the superstrate and substrate, the initiator being present in an amount of no more than 1 weight percent based on the total weight of the copolymer and the primer being present in an amount of no more than 0.5 weight percent based on the total weight of the copolymer and subjecting the thus formed laminate to an elevated temperature for a time sufficient to crosslink the copolymer and seal the photovoltaic cells in the crosslinked copolymer while at the same time binding the crosslinked ethylene/vinylacetate copolymer to both the substrate and superstrate.
