The PV industry is expected to eventually reduce its manufacturing costs well below €1/Wp. Major technological changes lie ahead of us for manufacturing wafers, solar cells and modules if this cost target is to be met. In order to focus R&D efforts amongst the myriad options, and to speed up the learning curve, the PV industry (equipment vendors, material suppliers and PV manufacturers) may benefit from collaborative efforts guided by an ITRS-like roadmap. In this paper we present the IMEC roadmap, the target of which is to reduce drastically the amount of pure Si needed per Wp by combining efficiencies beyond 20% with aggressive reductions in wafer thicknesses.
