Abstract

Abstract : Triflic acid dispersed in an apolar solvent exhibited a superior doping effect and stability on carbon nanotube electrodes. The carbon nanotube electrode-based perovskite solar cells exceeded the metal electrode-based counterpart in terms of efficiency. Abstract : Triflic acid dispersed in an apolar solvent exhibited a superior doping effect and stability on carbon nanotube electrodes. By applying a high concentration of a hole-transporting material on the carbon nanotube top electrode in perovskite solar cells, higher power conversion efficiency than that of metal electrode-based perovskite solar cells was obtained.
