Tie a ribbon on it: Multiwalled carbon nanotubes were partially unzipped to produce nanoribbons that bridged the nanotubes. The unique structure favors rapid charge transport when used as counter electrodes in dye-sensitized solar cells, resulting in a maximum energy conversion efficiency of 8.23 % versus 7.61 % for a conventional platinum electrode.
