Abstract
Herein, preparation of Cu2ZnSnS4 (CZTS) quantum dots (QDs) decorated reduced graphene oxide (rGO) nanocomposite by a simple and nontoxic solution method is reported. Structure and morphology of CZTS QDs, rGO and prepared composite have been analysed through XRD, TEM, Raman, XPS, UV-Vis and FESEM. Improvement in current in CZTS QDs-rGO composite compared to CZTS QDs could be attributed to the separation of electron-hole pairs generated in QDs and their rapid transfer to the surface of graphene sheets. This result suggests that the prepared composite could be used as promising materials for solar cell.
