Dr. Fan Fu is a group leader at Empa-Swiss Federal Laboratories for Materials Science and Technology. He received his bachelor's and master's degrees in materials science from the Wuhan University of Technology in 2010 and 2013, respectively. He joined Prof. Ayodhya N. Tiwari's group as a Ph.D. student in 2014 and earned his Ph.D. degree from ETH Zürich with distinction in 2017. His doctoral thesis on perovskite-CIGS thin-film tandem solar cells was awarded ETH Medal. From January 2018 to May 2019, he worked as a postdoc researcher in Prof. Christophe Ballif's group at EPFL. In June 2019, he joined Empa as a group leader. He is currently leading a research team investigating novel perovskite semiconductors for energy and optoelectronics applications. In particular, his group's recent research efforts focus on upscaling of high-performance perovskite-based thin-film tandem solar cells on flexible substrates.
