We have studied photovoltaic performance photodiodes based on reduced graphene oxide-iron oxide (RGO-Fe3O4) and multi-wall carbon nanotube-iron oxide (MWCNT-Fe3O4) nanocomposites. Characterization of the RGO-Fe3O4 and the CNT-Fe3O4 nanostructures is investigated in detail by X-ray diffraction (XRD), FT-IR spectroscopy and scanning electron microscope (SEM). RGO is synthesized using modified Hummers’ method oxidation of graphite powder. The photovoltaic properties of the RGO-Fe3O4/p-Si/Al and the MWCNT-Fe3O4/p-Si/Al photodiodes are analyzed. The maximum electrical power values of devices were found to be 12.9 μW and 10.4 μW under 100 mW/cm2 illumination, respectively. The devices exhibit photovoltaic behaviors with open circuit voltages (Voc) and short circuit currents (Isc). The diodes with MWCNT- Fe3O4 and RGO- Fe3O4 nanocomposites may be used as a photodiode in optoelectronic applications.
