Prof. Dr. Peng Gao studied since 2006 as Ph.D. at the Max-Planck Institute for Polymer Research (Mainz, Germany) in the group of Prof. Klaus Müllen. His Ph.D. thesis is about organic field-effect transistors. Since 2010, he joined the lab of Prof. Grätzel at EPFL (Lausanne, Switzerland) as a postdoctoral researcher and studied dye-sensitized solar cells and perovskite solar cells. From 2015 he worked with Prof. Nazeeruddin at the EPFL Sion Energy Polis ((Sion, Switzerland)) as a group leader on perovskite solar cell related semi-conductive materials. He started the Laboratory for Advanced Functional Materials in 2017 at Fujian Institute of Research on the Structure of Matter (FJIRSM), the Chinese Academy of Sciences, and focus on the application of rare-earth elements in organic optoelectronics and energy conversion materials.
