Abstract

Iron oxide nanowires were synthesized on stainless steel mesh substrate using the thermal oxidation process at the varying temperature of 750°C for 60 min. The samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD pattern showed that the iron oxide nanowires exhibited the structure of alpha-Fe2O3 (hematite). SEM images indicated that the diameter and the length of the nanowires were 80 to 285 nm and more than 5 μm, respectively. The dye-sensitized solar cell (DSC) properties based on the nanowires substrate was also studied. It was found that the power conversion efficiency (η) of the device was 0.11%.
