Abstract

This study proposes a grating structure solar absorber based on multi-layer stack design using Cr-InAs material. Through FDTD simulation calculations, it was found that within the range of 280–4500 nm, its absorption rate reached 92.33 %, and the weighted average absorption efficiency under AM1.5 spectral conditions reached 94.51 %. In order to explore the reasons for achieving broadband absorption with this structure, the electromagnetic field distribution at four absorption peaks was calculated. It was discovered that ultra-broadband absorption in the ultraviolet to visible light range mainly relies on propagating surface plasmon resonances between stacked layers, as well as the effects of Fabry-Pérot resonances. The thermal emission efficiency of this structure at high temperatures of 1000 K and 2000 K was then calculated, reaching 94.32 % and 96.21 % respectively. Additionally, this research investigated the impact of different refractory metal materials and various structures as well as different parameters on absorption efficiency by comparison. Finally, the model's sensitivity to changes in incident light angle and polarization angle was calculated. In summary, this structure can offer a viable option for achieving highly efficient solar energy absorption and photothermal conversion.
