We fabricate the organic photovoltaic (PV) devices, in which 4,4',4"-tris-(2-methylphenylphenylamino)triphenylamine (.m-MTDATA) and rare earth (RE) (dibenzoylmethanato)(3) (bathohenanthroline) (RE(DBM)(3) bath) (RE = Nd or Pr) are used as electron donor and acceptor, and investigate their PV properties. The PV diode fabricated in the optimum processing conditions shows the open-circuit voltage of 1.91 V, short-circuit current of 0.1 mA/cm(2),fill factor of 0.38, and the overall power conversion efficiency of 1.9% when it is irradiated under UV light (4 mW/cm(2)). The photocurrent density exhibits an increase of 20% at least when a very thin LiF layer is inserted between the RE-complexes and the Al cathode. A strong electroluminescence from the interface is also observed and the maximum luminance of a yellow emission resulted from the exciplex is 580 cd/m(2) at 17 V bias.
