1. A silicon nanostructured device comprising:

  • a non-nanostructured substrate;

    a nanostructured area disposed on and contacting a surface of the substrate;

    a passivating layer coating the nanostructured area, the passivating layer comprising one of aluminum oxide, silicon dioxide, or silicon nitride;

    a first contact comprising a comb-like pattern of metal directly contacting the nanostructured area;

    a p-n junction below the nanostructured area; and

    a second metal contact in electrical contact with the substrate.
