Figure 2

(a) Partial absorption spectra of (a,c) the top and (b,d) the bottom Au films in response to both p-polarized (a,b) and s-polarized (c,d) lights for our hot-carrier solar cell based on the combined structure of capped nanowires with top nanocones (red), the solar cells based on the nanocones only (pink) and the nanowires only (green), and the planar cell (blue), respectively. The solar spectral intensity is shown in all the four panels in light blue areas characterized by the right axes. The four solar cells involved in the comparison are schematically shown in the bottom inset. The geometrical parameters are s = 10 nm, h = 1 μm, r = 1 μm, p = 400 nm, and t top = 70 nm.
