Multiscale modelling of multidimensional molecular architectures for efficient organic solar cellsMarvin Nyenhuis, •Marcus Böckmann, and Nikos Doltsinis — Institut für Festkörpertheorie, Westfälische Wilhems-Universität, Münster, Germany

The active layer of bulk hetero-junction (BHJ) organic solar cells (OSCs) constitutes a complex mixture of polymeric donor (D) and acceptor (A) compounds [1] and its morphology is known to change upon ad hoc thermal annealing, thereby increasing the overall photoconversion efficiency (PCE). While experimental techniques like STM or AFM yield but detailed information of the surface structure, we use multidimensional Molecular Dynamics simulations [2] to elucidate the interior constitution of the layer at the atomistic level. In this contribution, we present insight obtained recently for the interpretation of morphology related UV-vis spectra and domain formation [3,4] together with current results on a novel polymeric D/A mixture [5].
