Probing Interfacial Properties in Polymer:Fullerene Bulk Heterojunctions — •Christian Kästner¹, Daniel A. M. Egbe², and Harald Hoppe¹ — ¹Institute of Physics, Technische Universität Ilmenau, Ilmenau, Germany — ²Linz Institute for Organic Solar Cells, Johannes Kepler University, Linz, Austria

We investigated the properties of donor-acceptor interfaces occurring in fine-tuned ternary bulk heterojunctions and were able to quantitatively correlate spectroscopic information with domain phase order. Relaxation energies for AnE-PV donor polymers as well as of PCBM were found to range within 100-200 meV.
