Abstract The recent rise of metamaterials opens new opportunities for absorbers due to their designed electrodynamic properties and effects, allowing the creation materials with effective values permittivity permeability that are not available in naturally occurring materials. Since first experimental demonstration 2008, literature has offered great advances metamaterial perfect (MMPAs) operating at frequencies from radio optical. Broadband indispensable thermophotovoltaics, photodetection,...
Abstract Subwavelength confinement of light with plasmonics is promising for nanophotonics and optoelectronics. However, it nontrivial to obtain narrow plasmonic resonances due the intrinsically high optical losses radiative damping in metallic structures.

To guide the design of plasmonic solar cells, theoretical investigation core (metal)-shell (dielectric) nanoparticles for light absorption enhancement in thin film Si cells is performed. In contrast to reported simulations and experimental results that rear-located surface plasmon on bare metallic preferred, core-shell demonstrate better performance when located front a cell. This has been attributed enhanced forward scattering with vanishing backward preserved over wide spectral range...

Nonradiative decay of surface plasmons (SPs) is usually considered an unwanted process. However, recent studies have proven that hot carriers generated from nonradiative SP can be used for photodetection circumvents the bandgap limitation in semiconductors.
