Abstract

A broadband metamaterial absorber with a unique symmetrical quadcopter-shaped resonator, operating in the visible spectrum between 400 and 800 nm is proposed in this work for effective solar energy harvesting. A SiO2 substrate, which is likewise reinforced by a tungsten ground plane, is utilized to print this centrally symmetrical structure. Across the whole visible band, the numerical findings show an extraordinary absorption exceeding 90% while having an average absorption of 97.2%. Furthermore, the structure shows a high photothermal conversion efficiency (PTCE) across a broad temperature range in solar thermophotovoltaic (STPV) systems. Notably, strong functionality and polarization independency across a large range of incident angles, indicates its promise as an adaptable solution for developing broadband optical applications and solar cell technologies.
