We report the preparation of highly interconnected ordered mesoporous carbon-carbon nanotube nanocomposites which show Pt-like dye-sensitized solar cell (DSSC) efficiency and remarkable long-term durability as DSSC counter electrodes. Nanocomposites of OMC and CNTs are prepared for Pt-free, highly efficient counter electrodes of DSSCs.
