abstract = {Recent simulations of the efficiency of polymer/fullerene
solar cells as a function of mobility predicted finite
optimum mobilities due to a decrease in open circuit voltage
for higher mobilities. We explain this decrease in open
circuit voltage with two features of the commonly used
model, namely, infinite surface recombination and an
integration over a distribution of separation distances of
electron and hole in a charge transfer state at the
interface between donor and acceptor molecules. Especially,
the assumption of a variable electron/hole pair separation
at the interface has a considerable influence on the open
circuit voltage.},
