Here, we describe the development of novel stainless steel (SS) counter electrodes (CEs) coated with a composite of carbon black and 3D networked polymers to replace conventional CE, Pt-coated fluorine-doped tin oxide (FTO). In this work, we successfully coated both a conductive corrosion protective layer (CCPL) and a catalytic layer (CL) with a composite of CBs and 3D network polymers onto an SS substrate using spray pyrolysis. The weights of the CB material incorporated into the polymer matrices of the CCPL and CL were 6 and 86%, respectively. The CCPL formed a compact dense structure that prevented corrosion due to electrolyte penetration, whereas the CL formed a nanoporous structure that provided a large surface area for increased catalytic activity. |
