Influences of illumination wavelength. Spatial distributions of photogenerated carriers inside a quarter of the calculated unit (a–c) with the same color bar, J-V curves (d–f), and IQE and η as function of N _d (g–i) for the 150-nm-d SiNWA photoelectrode under the illumination of λ = 365 nm (a, d, g), 590 nm (b, e, h), and 800 nm (c, f, i). The three lights possess the same photon flux of 1.24 × 10¹⁶ cm⁻² s⁻¹
