Key Points

Key points are not available for this paper at this time.

Abstract

The charge carrier lifetime in small molecule: C60 photovoltaic devices is increased by reducing the physical interface area availabe for recombination. For donor contents below 10%, the gain in open-circuit voltage (Voc) depends logarithmically on the interface area while the energy of the interfacial charge-transfer state ECT remains invariant.
