We demonstrate enhanced excitondiffusion in an organic photovoltaic cell through the incorporation of a phosphorescent sensitizer. The increase in excitondiffusion length is realized using a composite electron donor layer consisting of a -bis(naphthalen-1-yl)--bis(phenyl)-benzidine (NPD) host doped with the phosphorescent guest -tris(2-phenylpyridine) iridium . The presence of the phosphor at low concentration allows for the population of the long-lived NPD triplet state and an increase in . An increase in the NPD from to is extracted from measurements of the external quantum efficiency for donor layers containing . This enhancement leads to a improvement in the power conversion efficiency relative to devices containing an undoped donor layer.
