Abstract

A thermally stable ultra-broadband metasurface-based emitter comprising square-shaped Ni resonators on Si substrate was investigated. The planar 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 determine 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.

Ni-SiO2电池辅助热稳定宽带超材料发射极

研究了一种在硅衬底上由方形镍谐振腔组成的热稳定超宽带超表面发射极。该平面多层超材料发射器在400 ~ 8450 nm波长范围内具有94%的高发射率。在优化后的结构参数下，在900K时的热辐射效率为93.55%，光热转换效率为90.5%，表明发射腔对太阳能有较强的吸收能力。然而，结构参数和入射角的变化对热发射率的影响较小。研究结果表明，该结构在高效利用太阳能方面具有一定的潜力。
