Research question
We want to probe and understand the temporal dynamics of the initial generation and early evolution and migration of excitons in organic semiconductors. We further want to investigate the effects of the chemical structure and the physical environment on critical exciton properties, so that rational and practical guidelines for improved material and device design can be established.
Sustainability aspects
Lightweight and flexible light-emission and photovoltaic devices based on organic semiconductors can be fabricated by energy- and material-efficient printing and coating methods using sustainable materials. However, the energy-efficient operation of these devices is directly dependent on the appropriate understanding and tuning of the properties of the excitons, i.e. the bound electron-hole pairs. The proposed project aims to shed new knowledge on the fundamental exciton formation and migration process, and as contribute to the development of improved organic semiconductors for more efficient and sustainable lightemission and photovoltaic devices.
