Distributions of the amplitude of electric field for p-polarization at some representative absorption peak wavelengths for our hot-carrier solar cell based on the combined structure of capped nanowires with top nanocones (the first row): (a1) λ = 607.9 nm, (a2) λ = 696.5 nm, (a3) λ = 746.5 nm, (a4) λ = 889.0 nm, (a5) λ = 954.4 nm, (a6) λ = 1031.4 nm; the solar cell based on the nanocones only (the second row): (b1) λ = 642.6 nm, (b2) λ = 677.2 nm, (a3) λ = 704.2 nm, (a4) λ = 842.8 nm, (a5) λ = 969.8 nm, (a6) λ = 1096.9 nm; the solar cell based on the nanowires only (the third row): (c1) λ = 615.6 nm, (c2) λ = 642.6 nm, (c3) λ = 738.8 nm, (c4) λ = 819.7 nm, (c5) λ = 942.9 nm, (c6) λ = 1123.8 nm; and the planar cell (the bottom row): (d1) λ = 438.5 nm, (d2) λ = 754.2 nm. Distributions of the amplitude of electric field for s-polarization (a7) at λ = 527.1 nm for our hot-carrier solar cell, (b7) at λ = 546.3 nm for the cell based on the nanocones only, and (c7) at λ = 530.9 nm for the cell based on the nanowires only, respectively.
