What is it about?
An ITO free, highly conductive PET foil is fabricated by depositing aqueous single-walled carbon nanotube (SWCNT) ink that exhibits remarkable durability when exposed to severe mechanical stability tests. Excellent adhesion of the SWCNT film on PET was obtained by aging the ink overnight at 50 °C before deposition. A counter electrode for a dye-sensitized solar cell was fabricated by electro-polymerizing the PEDOT polymer over the SWCNT film which gave 7% solar cell efficiency and low (0.4 Ω cm2) charge transfer resistance.

Perspectives
Here we developed a carbon nanotube based ink for a counter electrode. This would enable ink-jet printed flexible solar cell (DSC) manufacturing.
