Organic optoelectronics

Organic semiconductors

Organic semiconductors in the form of conjugated molecules can be used in efficient light emitting diodes (OLEDs), solar cells and thin film transistors. Such devices rely on the control and understanding of fundamental excitations such as excitons, electron-hole pairs, and polarons, single charges dressed by the polarization field. Our mission in this broad research field is to understand the processes leading to exciton recombination and light emission (1) and exciton splitting to generate polarons (2). The two processes are relevant for OLEDs and solar cells, respectively.

Recently we have started a new research topic which aims to investigate the physical mechanism of doping by small molecules (3). We are conbining advanced optical characterization tools capable of probing polarons with classical methods of semiconductor electronics to look at localized and delocalized transport states.
