Imaging the ageing dynamics of polymer solar cells — •Marco Seeland, Rösch Roland, and Hoppe Harald — Institute of Physics, Ilmenau University of Technology, Weimarer Str. 32, 98673 Ilmenau, Germany

Nowadays, many attempts are existing on the route towards higher power conversion efficiencies in polymer solar cells. In addition, the lifetimes of such devices play a key role for the market entry as commercial products. To investigate the timescale of degradation processes, we applied long-time stability measurements with devices stored in the dark and under illumination and compare the results with luminescence images. The application of those techniques allows us to investigate the ageing dynamics in our devices consisting of an interpenetrating network of P3HT and PCBM, sandwiched between the ITO/PEDOT:PSS and aluminium electrode.
