A 3.3 V Output Voltage Optical Plasmonic Solar Energy Harvester

In this paper, the design of a graphene arrowbowtie nanoantenna mid-IR energy-harvester to power IOT wireless sensor is presented. For the first time, a sensitivity analysis of the mid-IR nanoantenna resonant frequencies in terms of different graphene number of sheets and chemical potential (𝝁 𝒄𝒑 ) without substrate and on a two-layer substrate composed of SiO2 and Si, is carried out. The obtained simulation results by 3D CST 2020 are useful to design an efficient infrared nanorectenna, composed of the nanoantenna and a rectifying MIM diode inside the gap. The analysis of the complete energy-harvester (EH), composed of an NxM nanorectenna array, a low-pass filter, and a DC-DC converter, is reported. With an output voltage value of 3.3 V, an output current of 10 mA, and an area of about 11,57 mm 2 , the proposed 1964x65467 nanorectenna array-based infrared energy harvester array represents an optimal solution to powering IoT wireless sensors.
