NiS/SnS Core-Shell Embedded Polyaniline Composite: Synthesis and Characterization

Abstract

Solar cell is a key topic of energy technology research. Recently, low dimensional nanostructure has brought up much attention to fabricate photovoltaic devices. Using nanostructure materials can improve not only efficiency but reduce the cost and size. The room temperature synthesis and characterization of the conducting polyaniline (Pani) films embedded with Co2+ doped, PVA capped NiS/SnS core-shell particles as photoluminescent boosters is reported. The photoluminescence intensity of the core-shell particles-Pani film had increased significantly. The scanning electron micrographs revealed coreshell structure and their periodic arrangement in the polymer matrix. The charge transfer resistance of the film was found to be 438 Ω. Periodic arrangement of the nanoclusters of the core-shell particles in the continuous conductive polymer matrix and high carrier density promise this material for the photovoltaic applications.
