A 3.3 V Output Voltage Optical Plasmonic Solar Energy Harvester
2021
In this paper, for the first time, the design of a solar energy-harvester (EH) based on plasmonic optical nanorectennas and without the step-up converter is presented. The novel optical harvester with a 49497∗14286 nanoarray of about 21,21 mm2 presents an output voltage value of 3.3 V and an output current of 10 mA.
A 2.6 V-10 μa Nanorectenna Harvester based on thermal radiation of the car exhaust system
2021
In this paper, for the first time, the design and simulation of a thermal nanorectenna energy harvester for harvesting the electromagnetic energy from the car exhaust system is presented. The nanorectenna system is composed of three gold arrow-bowtie nanoantennas with different resonance frequencies and a geometric nanodiode in the feed gap of each nanoantenna. The resonance frequencies at about 50 THz, 65 THz, and 83 THz correspond to the frequencies of the thermal radiation emitted from the exhaust tailpipe, catalytic converter, and manifold, respectively. The proposed $2.6 mathbf{V}-10 mumathbf{A}$ Energy Harvester with a nanoarray area of about 0,05 mm2 represents an optimum solution to…
A High-Efficiency Optical Energy Harvester based on a Low-Impedance Plasmonic Nanoantenna
2022
In this paper, for the first time, an investigation in terms of efficiency of an energy harvester based on a plasmonic nanorectenna array is proposed. The novel proposed mirrored-arrowhead nanoantenna presents a very low impedance value at the resonant frequency which reduces the mismatching between the antenna and rectifier circuit. Simulation results carried out by the CST 2020 Studio show a resistance value equal to 1.1 kohms at about 350 THz and a very wide bandwidth as the equivalent RF rhombic antenna. This study paves the way to nanoantennas for high-efficiency electromagnetic energy harvesting applications overcoming the photovoltaic technology.
A Novel Plasmonic Nanoantenna for High Efficiency Energy Harvesting Applications
2020
In this paper, the results of a geometric investigation of plasmonic nanoantennas for energy harvesting applications in terms of field enhancement and available power are presented. Optimum performances are obtained by a particular arrow-shaped bowtie nanoantennas geometry. The novel nanoantenna geometry is here presented. The simulations of the novel nanoantennas made of aluminium, on a three-layers substrate, composed by silicon, silicon oxide, and aluminium, carried out with CST 2018 tool, are reported and compared with the classical bowtie nanoantennas ones. This study can guide both the engineering and the fabrication of plasmonic nanoantennas.
