This study reports the preparation of Si nanowires (SiNWs) by selective electroless etching and fabrication of photovoltaic (PV) cells. It was found that the SiNWs with 3μm average length and 100nm average diameter were formed only in the areas not covered by the Cr electrodes. It was also found that average reflectance in the 400-1000nm wavelength range reduced from 35 to around 2 with the SiNWs. Furthermore, it was found that we could enhance the short-circuit current density of the PV cells from 11.5 to 21.8mA/cm2 and enhance conversion efficiency of the PV cells from 4.62 to 8.15 using the selective electroless etching.
