We report the photovoltaic response of composite films formed with poly(N\|vingcarbazde)(PVK) and fullerene C 60 by using the physical jet deposition technique. The steady and transient photovoltage (PV) data were obtained for five kinds of photocells formed between ITO and aluminum electrodes. We found the PV signal of PVK/C 60 two\|layer composite structure is enhanced by five orders of magnitude compared with those of single layer of pure PVK and its mixed (with C 60 ) films. The experiment...
