Analytical model of Graphene based antenna for energy harvesting applications

Recent advances in fabrication and characterization of nanomaterials have led to the intelligible applications of such nanomaterials in the next generation flexible electronics and the highly efficient photovoltaic devices.Nanotechnology has been used in thin film photovoltaic devices, and is considered as one of the most promising research area in power harvesting applications.Excellent electron transport properties of Graphene make it an attractive choice for next generation electronics and applications in energy-related areas.In this paper we present design and analytical model of graphene based nanoscale antennas for power harvesting applications.Unlike conventional solar cells that harvest energy in visible light frequencies range, we focus on design of nanoscale antenna to harvesting energy in UV spectrum range frequencies.Thought the irradiance of UV from sun is less than infrared and visible light frequencies, the excess energy of photons in UV frequency is greater than infrared or visible light frequencies and makeup for the lack of irradiance.
