Abstract:
1. A process for making a multilayer photovoltaic panel ( 10 ) by direct co-extrusion of polymeric material comprising the steps of: a) plasticizing polymers in a plurality of different dedicated extruders for lowering the viscosity of the polymers for subsequent manipulation of the polymers as a fluid; b) transporting the plasticized polymers through ducts to a stratification group; c) stratifying the plasticized polymers coming from the plurality of different dedicated extruders so that the plasticized polymers are arranged and coupled in the order in which they will be arranged in an end product, with flow rates which respect foreseen thickness and mass ratios of the plasticized polymers; d) co-extruding a flow made up of the different plasticized polymers; and e) consolidating the flow to form the end product through cooling until a film that is sufficiently thick so as to be able to be manipulated is formed, wherein said multilayer photovoltaic panel (
