degradation in printed polymer:fullerene thin films for organic photovoltaics — •Jan Richard Stockhausen, Peter Müller-Buschbaum, and Christoph Schaffer — TU München, Physik-Department, LS Funktionelle Materialien, James Franck-Str. 1, 85748 Garching, Germany

In comparison to conventional silicon solar cells, organic photovoltaics (OPVs) offer several advantages, like ease of production and a high versatility. Nevertheless, their lifetime needs to be prolonged, so that a profitable large-scale production becomes feasible. Therefore, a detailed understanding of the degradation mechanisms is necessary. In the present investigation, we address UV induced aging of PCPDTBT:PC71BM and P3HT:PCBM active layers, printed in a positive shim mask slot dye coater. Changes in the films due to accelerated aging are investigated by means of atomic force microscopy (AFM), X-ray reflectivity (XRR) and UV/Visible light spectroscopy (UV/Vis).
