Ni-SiO <sub>2</sub> Cell-Assisted Thermally Stable Broadband Metamaterial Emitter
A thermally stable ultra-broadband metasurface-based emitter comprising square-shaped Ni resonators on Si substrate was investigated. The planer multilayer metamaterial emitter exhibits high emissivity of 94% over a span of 400–8450 nm wavelength. With the optimized structural parameters, the results show the thermal emission efficiency of 93.55% and photothermal conversion efficiency of 90.5% at 900K, which determines strong solar energy absorption of the emitter cavity. However, variations in structural parameters and the angle of incidence leave a minor impact on thermal emissivity. The findings show the developed structure to be of potential in efficient solar energy utilization.
