The synthesis and characterization of the conducting polyaniline (Pani) films embedded with Co2+ doped, PVA capped NiS/CdS core-shell particles as photoluminescent boosters is reported. The photoluminescence intensity of the core-shell particles-Pani film had increased significantly. Periodic arrangement of the nanoclusters of the coreshell particles in the continuous conductive polymer matrix and high carrier density promise this material for the photoelectrochemical applications. Solid-state photovoltaic cells have been fabricated with NiS:Co/CdS-Pani as the electron conductor and Pani as the hole conductor. The cells show photocurrents of 0.1 mA/cm2, voltages of 304 mV and energy efficiencies of 0.58%.
