A durable SWCNT/PET polymer foil based metal free counter electrode for flexible dye-sensitized solar cells

Author affiliations

Abstract

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.
