Vanadyl phthalocyanine (VOPc) and fullerene (C60) composite nanoparticle having the diameter in the range of 15-60 nm has been prepared by reprecipitation methods from N-methyl-2-pyrrolidone/water solvent. The fabricated composite nanoparticles were compared with its monocomponent nanoparticles. The nanoparticles were characterized by UV-vis absorption, X-ray diffraction (XRD) and TEM methods. The UV-vis absorption indicates the formation of nanoparticles in the suspension state. The particle size measurements indicate that the composite particles are tending to form smaller particles than its monocomponent particles maybe due to faster nucleation in suspension state. The photoelectrochemical studies of composite nanoparticles were investigated in comparison with those of C60 (n-type) and VOPc (p-type) and the studies reveals that composite nanoparticles exhibit higher photoanodic current and also it possess n/p junction-like behavior.
