Prof. dr. Ruud E.I. Schropp joined the Energy Research Center of the Netherlands (ECN) at the Eindhoven location in the Solliance partnership in 2012, and has a professorship in Thin Film Photovoltaics at Eindhoven University of Technology. His research interests are c-Si/a-Si heterojunctions, next generation thin (nanostructured) films for photovoltaics, such as nanowire structures, nanophotonics, photon conversion, 3D nanostructures, and high efficiency hybrid tandem solar modules.
