This communication reports the discovery of a polymeric acid, tetrafluoroethylene-based fluoropolymer-copolymer sulfonic acid, functioning as an effective p-type dopant for transparent carbon electrodes. The polymeric acid exhibits high doping effectiveness which is durable for more than one year. Carbon nanotube transparent electrodes doped with the polymeric acid were used in organic solar cells. The devices show excellent efficiency with remarkable stability owing to the polymeric acid's strong acidity and stability.
