Description: Das Projekt "CIFAR Bio-Inspired Solar Energy: Coherence in the elementary processes of high-efficiency organic solar cells" wird vom Umweltbundesamt gefördert und von Technische Universität Dresden, Institut für Angewandte Photophysik, Professur für Optoelektronik durchgeführt. The key elementary step in organic solar cells is the separation of photogenerated excitons at the interface between donor and acceptor material. The most significant drawback of organic solar cells is the voltage loss which is involved in this step. Thus, it is of key importance to better understand the dynamics of this process. There are many parameters and sub-processes involved, e.g. the influence of the initial photogeneration energy, the detailed influence of the morphology at the interface, and the influence of relaxation into other paths like triplet states. Currently, organic solar cells based on thiophene derivates as donor absorbers deliver the highest efficiencies (12%, Heliatek) so far reported and see first commercialization. Nevertheless, the process of exciton separation is little investigated in particular in these small-molecule systems (much more work has been done for polymer solar cells). The topic of the investigation planned here is the influence of electronic and vibronic coherence on the process of exciton separation in high-efficiency small molecule solar cells.
