摘要

In the study, Finite Element Method simulations have been used to achieve a potential novel multi-layered solar absorber design. The absorber is made of different layers of Tungsten, Magnesium fluoride, Silicon dioxide, Silicene, and Gold. The key idea behind this design is to leverage the unique properties of each material to achieve efficient light absorption and control over light polarisation across a wide wavelength range of 0.1–3 µm. The goal was to determine the optimal combination of materials and geometry to gain the most achievable solar absorption. The proposed metamaterial exhibits exceptional absorption, approaching ideal absorption with values exceeding 99% across a broad wavelength range (0.1–3 µm). Furthermore, the design maintains its impressive efficiency even when sunlight hits the surface at an angle of up to 60°. This design paves the way for the development of a solar absorber capable of absorbing a broad spectrum of light wavelengths, ranging from ultraviolet to infrared, Consequently, solar power transmission efficiency is increased.
