A graphene-multi-walled carbon nanotube hybrid supported on fluorinated tin oxide as a counter electrode of dye-sensitized solar cells

► A hybrid material consisting of multi-walled carbon nanotubes and grapheme was used. ► The hybrid material provides a higher charge transfer rate and a lower internal resistance. ► Hybrid electrodes possesses higher rate of charge transfer and lower electron lifetime. ► Hybrid counter electrode cell performance reached 91.6% of platinized electrode.
