The international research group 'Organic Opto-Electronics' (OOE) explores hydrocarbon based electronics for light sensing, emission or conversion into electrical energy. Research focuses on fundamental photo-physical processes at the molecular and meso-scale and how they determine device performance and their physical limits. In addition, the group aims at translating these insights into novel device concepts for future electronic applications in energy and healthcare.
Devices based on semiconducting polymers benefit from a large variety of chemical structures and can be deposited using low-cost, solution-based deposition techniques.
Devices based on vacuum-processed small molecules benefit from a solid reproducibility as well as an effortless lateral structuring and vertical stacking.
Dielectric mirrors or distributed Bragg reflectors are high-quality mirrors with superior reflectivities up to 99.9%, rendering them ideal to combine with emitting or absorbing organic materials.
We study optical absorption and emission processes in thin film using a series of ultra-sensitive techniques.
