Abstract

In the work, we design and propose an ultra-broadband solar energy absorber based on metamaterial. The proposed pyramid structure is formed by five layers of a stacking. The average absorption across the range of 300-2616 nm is 98.83%. The physical mechanism is illustrated by electric field and magnetic field distributions, including the dielectric lossy property of itself in shorter wavelengths, Fabry-Perot (FP) resonance, and local surface plasmon resonance (LSPR) in longer wavelengths. The result indicates that the energy absorption spectrum can be well matched with the standard solar spectrum under AM 1.5 over the full range of 300 to 2700 nm, wiht only 1.18% loss. Ultimately, the influence of different materials and geometrical parameters on absorption is investigated. The absorber can achieve ultra-broadband perfect absorption, and has a simple structure that is easy to manufacture. The result of this work can be applied in many potential fields, such as thermal photovoltaic power generation, infrared imaging, solar cells, and other optoelectronic devices..
