Abstract: A profound understanding of the photophysical processes at donor/acceptor interfaces is integral for the optimization of the photo conversion efficiency (PCE) of solar cell devices. Time-resolved laser spectroscopy and electron microscopic investigations provide the key information to accomplish high PCE in polymer-fullerene-based solar cells. This device optimization enhanced the PCE from 2% in IC60BA-based to >9% in PC71BM-based solar cells, as presented by Omar F. Mohammed and co-workers in article number 1502356.​​
