Photon Management in Solar Cells

Ralf B. Wehrspohn studied physics at the University of Oldenburg, Germany, and received his Ph.D. degree from the Ecole Polytechnique in Paris in 1997. Until 1999 he worked on thin-film transistors for AMLCDs at Philips Research. From 1999 until 2003 he led the Porous Materials/Photonic Crystals group at the Max Planck Institute of Microstructure Physics in Halle, after which he held a chair at the Physics department of the University of Paderborn for three years. Since 2006, he has been the director of the Fraunhofer-Institute for Mechanics of Materials and a Professor of Physics at the Martin-Luther-University Halle-Wittenberg. Professor Wehrspohn was awarded the Maier-Leibnitz Prize of the German Science Foundation in 2003.Uwe Rau is full professor at RWTH Aachen (Faculty Electrical Engineering and Computer Science, chair of photovoltaics) since 2007 and is head of the energy research IEF-55 photovoltaic institute at the research center in Julich. He obtained his PhD 1991 from Physical Institute of the University Tubingen (Prof. Huebener) and was scientific group leader from 1995-2007 at the University Bayreuth and Stuttgart.Andreas Gombert is chief technology officer of Concentrix Solar, Freiburg, Germany, a division of the Soitec Group.
