| Abstract;The series resistance of p-i-n type organic photovoltaic devices was reduced by indium doping in the naphthalene tetracarboxylic dianhydride (NTCDA) layer, which leads us to a marked increase of conductivity based on a peculiar electronic interaction. Partial doping near the electrode interface brought about an increase of aspects of the photovoltaic performance, in particular, the short circuit current and fill factor. On the other hand, doping to the whole NTCDA film quenched the photogenerated excitons and degraded the performance. On the basis of measurements of the action spectra, the increase of photovoltaic performance was attributed to an increase in the collection efficiency of photogenerated carriers due to a reduction of the series resistance.
