The influence of typical degradative stresses on the constitutive parts of polymer/fullerene solar cells — •Vida Turkovic, Sebastian Engmann, Roland Rösch, Harald Hoppe, and Gerhard Gobsch — Technische Universität Ilmenau, Institut für Physik, Experimentalphysik 1, Weimarer Straße 32, 98693 Ilmenau

Improving the long time stability of organic photovoltaics is one of the key issues towards making them competitive with their inorganic counterparts. In order to separately investigate the degradation of the electrodes and the photoactive layer in thin film devices, we developed a simple approach based on ambient and inert atmosphere tests. The devices were characterized with standard spectroscopic measurements and electrical characterization, complemented by large-area imaging methods.
