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 a lamination step wherein the encapsulant material comprises a silane-modified polyolefin having a melting point below 90° C., pigment particles and an additive comprising a cross-linking catalyst; and wherein in said lamination step heat and pressure are applied to the module, said heat being applied at a temperature between 60° C. and 125° C.
