In this paper, we report the photoconductivity property of different poly (p-phenylene vinylene) (PPV)/C₆₀ composite films fabricated by physical jet deposition technique. The results indicate that the photoconductive enhancement effect in PPV/C₆₀ composite films depends on the different charge transfer efficiency at the interface between PPV derivatives and C₆₀. The wavelength dependence and temporal evolution of photoconductivity of composite films were also measured in our experiments, and it was found that some PPV/C₆₀ composite films showed quite better photoresponse and stability. It can be expected that the conjugated polymer/fullerene composite film optimized by an appropriate configuration have the potential application in thin-film photoelectric devices.
