Influence of surface characteristics on electronic properties of polymer thin films — •Philipp Ehrenreich, Susanne Birkhold, Alexander Graf, Eugen Zimmermann, Hao Hu, Kwang-Dae Kim, and Lukas Schmidt-Mende — Department of Physics, University of Konstanz, POB M 680, Konstanz 78457, Germany

Many applications in polymer electronics demand not only for a loss-free charge percolation pathway towards electrodes, but also a highly delocalized pi-orbital system for efficient charge generation after exciton dissociation. The latter is especially important for the development of all-polymer solar cells, in order to compete with fullerene-based devices. Within this work the influence of surface characteristics on structural, or rather electronic properties of polymer thin films is investigated by means of an H/J-aggregate analysis on the model polymer Poly(3-hexylthiophene).
