VitaF. Lombeck

Florian Lombeck  studied chemistry at the university of Heidelberg and finished his studies with a focus on the synthesis and characterization of organic fluorescent dyes for OLED application. During his studies he spend 6 months at the Department of Photochemistry and Molecular Science in Uppsala, Sweden, where he conducted research on light-harvesting complexes for water-splitting. In a close and interdisciplinary collaboration with the Department for Macromolecular Chemistry of the University of Freiburg Florian received his PhD physics from the Cavendish Laboratory in Cambridge, UK. He investigated conjugated polymers for organic photovoltaic (OPV) and organic light-emitting diodes (OLED) in regards to phase separation behavior of conjugated polymer/polymer blends and conjugated polymer backbone defect structures upon the performance of the final optoelectronic devices. Since February 2018, Florian Lombeck is working at Hahn-Schickard on the development of membranes for application in PEM fuel cells and redox-flow-batteries.
