Polymer Solar Cells — •Harald Hoppe — Institut für Physik, Technische Universität Ilmenau, Germany

Milestones in the development of conjugated polymer-based solar cells are reviewed. The presentation will cover an introduction to elementary photo-physical processes and fundamental working principles of polymer solar cells. Furthermore, processes limiting the individual photovoltaic parameters are discussed. Interesting examples of structure-property-relationships on the super-, inter- and intra-molecular scale are given and demonstrate the necessity for multi-scale approaches in the optimization of polymer solar cells. Finally, several so far utilized donor-acceptor material systems are briefly reviewed.
