Abstract :

In the present study, graphene oxide : zinc oxide nanocomposites will be synthesized by hydrothermal or sol-gel method. X-ray diffraction results confirm the nanostrcture of, graphene oxide: zinc oxide nanocomposites. Graphene based solar light sensitive photodiode was fabricated. The photo-response properties of the diode were investigated by I-V and C-V measurements. The reverse current of the diode increases with solar light intensity. This suggests that the prepared device exhibits a photodiode behavior. The photo-response mechanism of the diode was analyzed by transient photo-capacitance measurements. The obtained electrical and photocurrent measurements suggest that graphene based solar light sensitive photodiode can be used as a sensor in optoelectronic applications.
