Photon Management in Solar Cells
Bu e-kitab haqqında
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.

Ralf B. Wehrspohn studied physics at the University of Oldenburg, Germany, and received his PhD degree from the Ecole Polytechnique in Paris in 1997. Until 1999 he worked on thin-fi lm 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 studied physics at the University of Tübingen, Germany, and at the University Claude Bernard, Lyon, France. He obtained his PhD 1991 from the Physical Institute of the University Tübingen. From 1991-1993 he worked at the Max Planck Institute for Solid-State Research. He was scientifi c group leader from 1993-2007 at the University Bayreuth and at the University Stuttgart. Since 2007 he is full professor at RWTH Aachen (Faculty Electrical Engineering and Information Technology, Chair of Photovoltaics). Simultaneously he is director of the Institute of Energy and Climate Research IEK5-Photovoltaics at Forschungszentrum Jülich).
Andreas Gombert studied photo engineering and optics in Cologne, Germany, and Strasbourg, France, and received his PhD from the University Louis Pasteur, Strasbourg. His professional career started in 1986 at the Fraunhofer Institute for Physical Measurement Techniques in the fi eld of integrated optics. From 1991
to 2008, he worked at the Fraunhofer Institute for Solar Energy Systems where headed the department Materials Research and Applied Optics. Since 2008 he is Vice President System Platform and R&D and since 2014 also Managing Director of Soitec Solar GmbH, Freiburg, Germany, a division of the Soitec Group. He lectures at Technical Faculty of the University of Freiburg, Germany where he also habilitated.
