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 .
