Ultra-broadband perfect solar energy absorber based on tungsten ring arrays

Yu Cheng et al.

Summary: The novel solar energy absorber based on tungsten ring array proposed in this paper demonstrates excellent broadband and efficient absorption performance in the wavelength range of 300 to 2000 nm, with an absorption efficiency of over 90%. Broadband absorption is achieved through the excitation of surface plasmons and Fabry-Perot resonance effect, and due to the high symmetry of the structure, it is relatively independent of incident angle and polarization angle. This absorber shows promising application prospects in the fields of solar energy utilization, photothermal conversion, and infrared detection.
