Abstract

The charge carrier lifetime in small molecule: C photovoltaic devices is increased by reducing the physical interface area availabe for recombination. For donor contents below 10%, the gain in open-circuit voltage (V) depends logarithmically on the interface area while the energy of the interfacial charge-transfer state E remains invariant. © 2014 WILEY-VCH Verlag GmbH & Co.
