Abstract

Method of manufacturing a photovoltaic module comprising at least a first layer and a second layer affixed to each other by means of an encapsulant, said method comprising steps of:

providing a lamination device;disposing said first layer in said lamination device,disposing upon said first layer an encapsulant material manufactured by the steps of: providing a base resin comprising a silane-modified polyolefin and having a melting point below 90° C.,forming a mixture of said base resin and an additive comprising a crosslinking catalyst, said cross-linking catalyst being present in a proportion of 0.01 to 5 parts per hundred of resin,melting said mixture at a temperature between 90° C. and 190° C., preferably between 160° C. and 180° C. and extruding said mixture to form said encapsulant material; disposing said second layer upon said encapsulant material,laminating said first layer, said second layer and said encapsulant material under application of heat and pressure, said heat being applied at a temperature between 60° C. and 125° C., preferably between 60° C. and 100° C., further preferably between 70° C. and 90° C. so as to crosslink said base resin.
