(a) Characteristic line shape of a rear-located core-shell nanoparticle on a 2 μm thick Si (t = 60 nm, P = 400 nm). (b) Global tilt solar spectrum, together with graphs that illustrate the solar energy absorbed in a 2 μm thick Si film (assuming single-pass absorption and no reflection coating), a 2 μm thick Si film with a 120 nm Au sphere (P = 400 nm) located on the rear surface and a 2 μm thick Si film with a core-shell nanoparticle (t = 60 nm, P = 400 nm). (c) Angular scattering of a core-shell nanoparticle on a 2 μm thick Si film under 906 nm illumination (t = 60 nm, P = 400 nm).
