Ultra-broadband and wide-angle solar absorber with hierarchical nanohole design based on MXene

A tungsten-based metamaterial emitter for solar thermophotovoltaic systems

“…The emission spectrum can be ignored when the angle changes in the range of 0–60°, which indicates that it is insensitive to angles, which is very critical in practical applications. 55…”

A wide angle broadband solar absorber with a horizontal multi-cylinder structure based on an MXene material

“…21 Krishnakali et al designed a broadband plasma absorber based on the MXene cylindrical array with an absorption efficiency of 85% within the range of 600 to 2100 nm. 22 Although previous researchers have designed some absorbers based on MXenes, the related research is not yet in-depth enough, and the designed absorbers still suffer from the problem of having a narrow absorption bandwidth and lower average absorption efficiency. Therefore, designing an MXene absorber with ultra-broadband capabilities remains a promising research direction.…”
