My Research is concerned with optical and electronic processes in organic semiconductors. These materials are of high interest to industry as they combine the mechanical and processing properties of semiconductors with the electronic properties of semiconductors. This allows for the development of novel solar cells, light-emitting diodes and transistors. The industrial development of such technologies requires a comprehensive understanding of their scientific foundations. Thus, my research focusses on understanding how excitations and charges are created in organic semiconductors, how they decay, what their properties are and which opto-electronic processes they allow for. To this end, I employ a broad range of techniques centered on absorption and luminescence spectroscopy as well as device characterization.
