Dr. Uli Würfel studied Physics at the Universities of Freiburg and Heidelberg. He received his Ph.D. in Physics from the University of Freiburg in 2006 with the topic "Electron transport in the nanoporous TiO2 layer of dye solar cells", which was carried out in close collaboration with the Fraunhofer ISE. Since 2009, he has been a project leader at Dye and Organic Solar Cells Department of Fraunhofer ISE and is currently the Head of Department Organic and Perovskite Photovoltaics. His main research interests are characterization and modelling of organic and other types of solar cells and the upscaling of organic solar cells.
