Counter electrodes from polyaniline−carbon nanotube complex/graphene oxide multilayers for dye-sensitized solar cell application.

Highlights: [•] PANi-SWCNT complexes are synthesized by a reflux method for rapid charge-transfer. [•] (PANi−SWCNT/GO)n multilayer CEs are fabricated by a self-assembly technique. [•] The charge-transfer ability toward iodide reduction is significantly enhanced. [•] A conversion efficiency of 6.88% is obtained in its DSSC. [•] The strategy provides new opportunities for efficient DSSC assembly. [ABSTRACT FROM AUTHOR]
