Composites of Carbon Nanotubes and Graphene for Energy Conversion and Wearable Sensing

Abstract

Composites of carbon nanotubes and graphene can give rise to superior function arising from the synergistic effects of the two components. Here, I will present some of our works in investigating the application of carbon nanotube/graphene composites in dye-sensitized solar cells and wearable sensors. The carbon nanotube/grpahene composites prepared by gel coating can effectively catalyze the regeneration of the redox species of dye-sensitized solar cells. They can give rise to a photovoltaic efficiency higher than that with carbon nanotubes, graphene or Pt as the counter electrode. Moreover, we prepare hybrid carbon nanotube/graphene on fibrics. They are sensitive to strain and can be used as washable wearable sensors.
