Prof. Dr. Andreas W. Bett is director of the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg, Germany and Professor of “Solar Energy Materials and Technologies” in the Faculty of Mathematics and Physics, University of Freiburg. He received the Dipl. degree in physics and the state examination in physics and mathematics from the University of Freiburg, Germany in 1988 and 1989, respectively and the PhD degree in physics from the University of Konstanz, Germany in 1992. He joined the Fraunhofer Institute for Solar Energy Systems, ISE in 1986. In 1993 he became the head of the group “III-V – epitaxy and solar cells”. From 2007 until 2016 he was division director “Materials – Solar Cells and Technology” and from 2009 until 2016 he was deputy director of the institute. In 2017 he was appointed director of the institute.

The main areas of research of Prof. Dr. Andreas Bett include solar silicon material, epitaxial growth of Si and III-V semiconductors, development of characterisation techniques for advanced solar cell devices and the fabrication of solar cells. Furthermore, he develops concentrator module and systems and is involved in field testing.
For his scientific achievements he was honored with several prestigious prizes. He has organized several international conferences and served in many scientific committees. He was also co-founder of the company Concentrix Solar in 2006 and in 2015 of the company NexWafe. In the ESYS project, Andreas W. Bett is involved as co-leader in the working group "Development of Photovoltaics and Wind Energy".
