Studying the Effects of Degradation in Organic Solar Cell Materials — •Michael Adams1, Ian Howard1, Bryce Richards1, Andreas Weu2, and Yana Vaynzof2 — 1Institute of Microstructure Technology, Karlsruhe Institute of Technology (KIT), 76344 Eggenstein-Leopoldshafen, Germany — 2Center for Advanced Materials, University Heidelberg, 69117 Heidelberg, Germany
Many factors have been reported to affect the stability of OPVs, among them are exposure to light, humidity, temperature and oxygen concentration. In order to develop strategies against these degrading effects we need to have a better understanding of the fundamental processes in the device's active layer. One of the most efficient OPV material combination to date is P3HT:PCBM. We perform transient absorption and streak camera measurements on P3HT:PCBM samples that have been prepared and degraded at the University of Heidelberg under various environmental conditions with the goal to identify differences in the photophysical processes occurring in these devices.
