Dr. Christoph Luderer

Researcher

Christoph Luderer studied physics at the University of Stuttgart and the University of Göttingen. From 2017 to 2021, he worked as a PhD student at the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg in the field of Si photovoltaics (Sustainable Systems Engineering) and received his doctorate from the University of Freiburg in 2021. His dissertation dealt with the charge carrier transport properties of thin films and functional interfaces in solar cells with passivating contacts. He then worked for two years as a process engineer in semiconductor manufacturing at Robert Bosch GmbH in Reutlingen. Since November 2023, he has been working as a research associate in the Competence Center Energy Policy and Energy Markets at the Fraunhofer Institute for Systems and Innovation Research ISI in Karlsruhe.
