(a) Absorbed power broken down by material layer, at varying incident photon wavelength for a RJ cell with SiNW length of Lw = 1.7 μm and i-layer thickness of Ti = 100 nm. (b) Percentage of effective absorption in the i-layer relative to total absorption in the RJ multilayer structure. (c) Evolution of the absorption spectra in the active i-layer with different Si nanowire lengths from Lw = 0.6 um to 1.7 μm. (d) full spectrum integrated absorption in i-layer as a function of SiNW length. This trend is then fitted by Lambert-Beer law as marked by the red line.
