[摘要]：We investigated the effect of doping with copper nanoparticles (Cu NPs) on photoconductivity of poly(3-hexylthiophene) P3HT films. similar to 20 nm Cu NPs were fabricated in a simple one step reduction process in hydrophobic environment. Structure, morphology and optical properties of the Cu nanoclusters were characterized. Films of P3HT containing Cu NPs were fabricated and their optical and electrical properties investigated. The results indicate that the change of the efficiency of the light absorption brought about by the effect of plasmonic resonances is minor, but there is a substantial influence of the metal nanoparticles on the efficiency of the photogeneration of charges in P3HT.
