Abstract

Photogeneration of charge carriers is studied in poly-N- epoxypropylcarbazole (PEPC) doped by C60/C70 fullerene condensate (30/70 mol.%). Efficiency (phi) of the charge carrier photogeneration was determined using the electrophotography technique with tritium ionizer. That efficiency is shown to increase monotonously with the fullerene concentration growth. A characteristic feature of the spectral dependence (phi) (lambda) is an increase of (phi) in the absorption region of the fullerene-sensitized PEPC. The initial efficiency of the charge carrier photogeneration (phi) 0 and thermalization radius r0 are determined.
