    We have synthesized SiNWs by CVD of silane on molybdenum substrates. Unlike other works when the SiNWs have been prepared mostly in crystalline form, our SiNWs possess more complex structure: thin crystalline core covered by amorphous jacket. Absorptivity is more than 98 % in the whole range of visible radiation 400-800 nm. During photoelectrochemical experiments a strong evolution of bubles was seen on SiNW deposit after irradiation of AM 1.5 G at 1 sunlight intensity. We suppose that the NWs are good candidates to substitute the standardly used tripple junction amorphous silicon (3jn-a-Si) layer system.
