Recent development of carbon nanotubes materials as counter electrode for dye-sensitized solar cells

Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode  generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes  have shown significant properties such as cost-effectiveness, environmental friendliness, availability, corrosion resistance and excellent catalytic activity towards the redox species make them ideal for replacing Pt in the CEs of DSCs. The review presented below gives a succinct summary of the Carbon nanotubes materials in use as counter electrode  in dye-sensitized solar cells .
