Researcher Scientist  at Fraunhofer ISE Leader “III-V cell and module characterization team

Dr. Gerald Siefer has joined the Fraunhofer Institute for Solar Energy Systems in Freiburg Germany as assistant student in 1997. Since then his work is focused on the characterization and calibration of photovoltaic devices. He finished his PhD on the topic of “Analysis of the performance of multi-junction cells under realistic operating conditions” in 2008. Since 2009 he is leading the team “III-V cell and module characterization. His team is working on calibration techniques for multi-junction solar cells with up to 6 pn junctions for space and terrestrial concentrator applications as well as on the indoor and outdoor characterization of concentrator modules. He has been participating as member of the scientific committees of several international PV conferences and is active member of the IEC working group 7 working on the development of international standards related to CPV.
