Electronic characterization of photoactive conjugated polymers — •Stefan M. Prams, Matthias A. Ruderer, and Peter Müller-Buschbaum — TU München, Physik-Department LS E13, James-Franck-Str. 1, 85747 Garching (Germany)

It is well known that in organic photovoltaics the molecular conformations as well as the polymer phase morphology in the active layer define the performance of a device. Typically the systems are optimized via pre- and postproduction treatments like the choice of the solvent or annealing steps. Furthermore ageing and degradation influence the performance during operation. In this work we characterized the electronic behavior of a system of selected photoactive conjugated polymers depending on pre- and postproduction treatments and ageing with a solar simulator. The investigations are completed with UV/Vis, FT-IR and thickness measurements.
