Dr. Felix Lang is heads the ROSI (Radiation-Tolerant Electronics with Soft Semiconductors) Group in the Physics and Optoelectronics of Soft Matter Department at the University of Potsdam. Felix Lang earned his degree in Physics from Technische Universität München and Freie Universität Berlin, and his Ph.D. from the Technical University Berlin. He then conducted his Ph.D. research on the stability and degradation of perovskite solar cells at the Helmholtz-Zentrum Berlin.

Following his Ph.D., Dr. Lang was awarded a Feodor-Lynen Fellowship, which he used to conduct further research in the group of Prof. S. Stranks at the Cavendish Laboratory of the University of Cambridge, UK. There, he worked on testing and developing next-generation perovskite tandem photovoltaics for space photovoltaics. After completing his fellowship, Dr. Lang returned to Germany with a return fellowship from the Alexander von Humboldt Foundation and joined the University of Potsdam to focus on a deeper understanding of the degradation, working, and loss mechanisms of perovskite-based tandem photovoltaics.

Dr. Lang's work in this field earned him a prestigious Freigeist-Fellowship from the Volkswagen Stiftung. Currently, Felix Lang is setting up the Tolerant Electronics with Soft Semiconductors Group at the University of Potsdam.
