摘要：

The charge carrier lifetime in small molecule: C-60 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-oc) depends logarithmically on the interface area while the energy of the interfacial charge-transfer state E-CT remains invariant.
