Core/Shell/Shell Nanowire Photocathodes for Neutral pH Water Splitting


Silicon is the most widely used semiconductor for solar cells [ 1–4 ] and has also shown promising performances in photoelectrochemical (PEC) cells for hydrogen production. [ 5–10 ] Silicon photoelectrodes with nano/micro structures such as nano/ micro wire array [ 9,11 ] and black silicon [ 7 ] have exhibited improved PEC performances. Silicon nanowire (NW… (More)
