To fully exploit the potential of organic semiconductors for solar cell, sensor, or photonic applications, we need to understand how their dynamics couple to their electronic structure for an improved rational design. At the level of single molecules, the reorganization energy is a first indicator for efficient charge transport allowing for a simulation-guided preselection of promising new materials for synthesis. By restricting the degrees of freedom of flexible side groups, contributions from low-energy molecular vibrations can be reduced. At donor-acceptor interfaces in organic solar cells, broad charge transfer exciton bands reduce the device’s efficiency. A combination of molecular dynamics and time-dependent density functional theory

Sebastian Schellhammer studied Physics at Technische Universität Dresden (Germany). Already in his diploma thesis, he focused on the analysis of electronic structure and transport properties of organic semiconductors based on materials simulations. He obtained the Diplomphysiker degree in 2011. Under the supervision of Prof. Gianaurelio Cuniberti and Dr. Frank Ortmann, he further extended his multiscale theoretical studies during his Ph.D. studies, which he finished in 2020. For several years, he was project coordinator in higher education and teacher education. Since 2022, he is group leader in Sebastian Reineke’s group at Technische Universität Dresden complementing the various experimental research activities by multiscale materials simulations.
