Abstract

In this paper, a study is conducted into optimization of quantum and coupling efficiency of solar rectennas. The optical antenna impedance is calculated using Method of Moment, whereas the Metal/Insulator/Metal (MIM) diode characteristics are calculated using Simmons' formula of tunneling current. The diode resistance and the responsivity have been determined based on the I-V characteristics of the MIM diode. Additionally, the quantum and coupling efficiency have been calculated from the diode and antenna resistances as well as the diode responsivity. Furthermore, both efficiencies have been optimized by finding the optimum values of the insulator layer thickness and the metal work function difference.
