Light-absorption selection of single nanoparticle for solar radiation requires the simultaneous fulfillment of all of the following novel conditions—maximal close (overlap) of the dependence of nanoparticle efficiency absorption factor on wavelength with the dependence solar irradiance, predominant role of nanoparticle absorption over its scattering, the use of maximal values of nanoparticle efficiency absorption factor and its size. These results highlight the possibility for effective application of single homogeneous Ti and core–shell Ti–TiO2, Ni–NiO nanoparticles with radii of about 75 nm as perfect absorbers for solar radiation in the complete optical spectrum 250–2500 nm. |
