Functionalized Graphene/Polyaniline (Pani@Grn) Nanocomposites for Organic Solar Cells

Abstract

Nanocomposites of graphene materials and conducting polymers have undergone substantial research as potential organic solar cell materials. In this paper, we present a graphene/polyaniline (PANI@GRN) self-assembly fabrication method of a graphene and polyaniline monolayer. Polyaniline (PANI)-functionalized graphene nanosheet nanocomposites were fabricated successfully. By in-situ polymerizing aniline in the presence of GRN, PANI functionalization was carried out, and it was employed to effectively and uniformly disseminate the substance. AFM, X-ray diffraction (XRD), fourier transform infrared (FTIR), and Raman spectroscopy were used to discover the selective synthesis of polyaniline on graphene. The composite films showed a small shift in G-band compared to the graphene sample due to a charge transfer between PANI and GRN, which thus confers/imparts the device improved photovoltaic properties.
