TCO-free conducting polymers/carbon cloths as the flexible electro-catalytic counter electrodes for dye-sensitized solar cells

Abstract

A TCO-free counter electrode of a sulfonated-polythiophene/carbon cloth gave a good cell efficiency (<italic>η</italic>) of 8.45% to its dye-sensitized solar cell, indicating its attractive potential to replace the expensive Pt/FTO (<italic>η</italic> = 8.07%).
