Written by renowned experts in the field of photon management in solar cells, this one-stop reference gives an introduction to the physics of light management in solar cells, and discusses the different concepts and methods of applying photon management.
The authors cover the physics, principles, concepts, technologies, and methods used, explaining how to increase the efficiency of solar cells by splitting or modifying the solar spectrum before they absorb the sunlight. In so doing, they present novel concepts and materials allowing for the cheaper, more flexible manufacture of solar cells and systems.
For educational purposes, the authors have split the reasons for photon management into spatial and spectral light management.
Bridging the gap between the photonics and the photovoltaics communities, this is an invaluable reference for materials scientists, physicists in industry, experimental physicists, lecturers in physics, Ph.D. students in physics and material sciences, engineers in power technology, applied and surface physicists.

Autor

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.
