Solar Cell Degradation Observed Directly for the First Time

With the help of DESY’s X-ray light source PETRA III, researchers of Technische Universität München have, for the first time, watched organic solar cells degrade in real time. This work could open new approaches to increasing the stability of this highly promising type of solar cell. The team headed by Prof. Peter Müller-Buschbaum from the Technische Universität München (Technical University of Munich) present their observations in this week's issue of the scientific journal Advanced Materials (Nr. 46, 10 December).
