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.
