Two-Dimensional Modeling of Silicon Nanowires Radial Core-Shell Solar Cells

Figure 1

(a) Schematic of nanowires radial core-shell junction solar cell used in the model. The incident light is in parallel to the SiNWs axis; (b) optical absorption spectra of the SiNWs array versus diameter 300 nm, 400 nm, and 500 nm. 2 μm thick silicon substrate serves as reference. The radio of d/P is set as 0.5.
