Abstract

Conducting polymer–graphene hybrid nanocomposites have emerged as promising materials for next-generation optoelectronic applications owing to their solution processability, tunable interfacial properties, and mechanical flexibility. Recent studies have highlighted the importance of graphene–polymer hybrid systems in enhancing charge transport pathways, exciton dissociation efficiency, and interfacial stability in organic optoelectronic devices. Despite these advantages, a key challenge remains the efficient production of individual graphene sheets through the reduction of graphene oxide using inexpensive, scalable, and solution-processable techniques that are compatible with sustainable and environmentally benign processing. In this work, an eco-friendly, single-step chemical reduction strategy is employed to reduce graphene oxide using L-glutathione (GSH) as a green reducing agent, targeting optoelectronic applications such as organic photovoltaics. Nanocomposites of green-route reduced graphene oxide (rGO) are blended with conducting regioregular poly(3-hexylthiophene) (P3HT) to investigate polymer-mediated electron transfer processes and interfacial interactions. The reduction of graphene oxide and its dispersion within the polymer matrix are characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM). Electron transfer behavior in the nanocomposites is examined using UV–Vis absorption and photoluminescence (PL) spectroscopy. The observed photoluminescence quenching indicates efficient exciton dissociation and suppressed radiative recombination in rGO–P3HT blends, confirming enhanced excited-state electron transfer at the polymer–rGO interface and highlighting the potential of eco-friendly polymer–graphene nanocomposites for sustainable optoelectronic applications.

Keywords: Reduced Graphene Oxide (rGO), P3HT Polymer, Nanocomposites, Organic Solar cells, Electron Transfer
