چکیده مقاله:

Fe3O4 -reduced graphene oxide (Fe3O4-RGO) counter electrode (CE) is prepared as a counter electrode for dye-sensitized solar cell (DSSC). Fourier transform infrared spectroscopy (FTIR) energy dispersive spectrometer (EDS) and field emission scanning electron microscopy (FESEM) indicate clearly the formation of Fe3O4-RGO nanocomposite. To evaluate the chemical catalysis and stability of prepared CEs toward I3- reduction and the interfacial charge transfer properties, Fe3O4-RGO nanocomposite have characterized by cyclic voltammetry. Under AM 1.5 irradiation (100 mW cm-1), the DSSC based on the Fe3O4-RGO show a maximum power conversion efficiency (PCE) of 5.91%, suggesting that the Fe3O4-RGO nanocomposite is one of effective CE materials for low-cost DSSCs.
