High-performance bilayer counter electrodes (BCEs) for dye-sensitized solar cell (DSSC) applications are gaining considerable attention. In this study, MoS2 /single-walled carbon nanohorn (SWCNHs) BCEs were fabricated by ultrasonic-spray-assisted electrochemical deposition. The BCEs exhibited superior electrocatalytic activity, confirmed through CV, Tafel plots, and electrochemical impedance spectroscopic studies. The fabricated MoS2 /SWCNH-based DSSCs exhibited an impressive photovoltaic power conversion efficiency of 9.48 %, which is higher than the performance of cells with Pt-containing CEs (8.64 %). The simple and reliable growth strategy for bilayer film CEs provides a new route for the preparation of cost-effective and high-performance catalytic BCEs for renewable energy applications involving Pt-free DSSCs.
