Tungsten-alumina-graphite based metamaterial absorber with concentric ring cavities for efficient solar energy harvesting
This paper presents a novel broadband metamaterial perfect absorber (MPA), featuring a concentric ring cavity-based structure. The design utilizes a tungsten-alumina-graphite three-layer configuration, achieving over 90% absorption across 200–000 nm wavelengths, with peak absorption exceeding 99% in key solar spectrum ranges. Optimization through parametric analyses enhances performance across UV, visible, and near-infrared regions. The absorber demonstrates polarization insensitivity due to symmetrical unit cell structure and high efficiency for incident angles up to ± 45°. The calculated total solar absorption efficiency ranges from 92 to 97% and the solar thermal efficiency is 93% and the total thermal emissivity is 93%. The use of thermally stable materials potentially enables high-temperature applications. Numerical simulations validate the design’s effectiveness, contributing to the development of more efficient solar energy harvesting devices.
