Who we are
We are a young and dynamic research group based in Bern, Switzerland, and led by Prof. Natalie Banerji. In our group, chemists as well as physicists and material scientists work side by side to understand and optimize electronic devices based on organic electronic materials. In addition, we combine the best of two worlds by welcoming researchers from all over the world and by teaching local students from Bern.
This combination of different backgrounds and experiences forms a powerful symbiosis that enables us to understand the underlying principles of charge transport in the materials we study.
Our research interests
Our objective is to understand fundamental material properties (e.g., light–matter interactions, electron transfer processes, charge transport, molecular recognition) of organic and hybrid semiconductors, with applications in new generation solar cells, organic transistors, and organic bioelectronics. The current gap between missing fundamental understanding and the blind development of applications needs to be filled in order to achieve intelligent design of high-performance devices.
Our research revolves around the central question of what happens on the ultrashort time scale and ultrasmall length scale in organic solids to induce macroscopic function in devices, and how this can be optimized. Experimentally, we use a complementary palette of techniques combining (time-resolved) spectroscopy, pulsed photocurrent methods, terahertz experiments, Stark-effect spectroscopy, and device testing.
