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.

基于化学沉积在双层反电极上的MoS2 /单壁碳纳米角的染料敏化太阳能电池（DSSC）的增强性能

用于染料敏化太阳能电池（DSSC）的高性能双层对电极（BCE）受到了广泛关注。在这项研究中，MoS ₂ /单壁碳纳米角（SWCNHs）BCE是通过超声喷涂辅助电化学沉积制备的。通过CV，Tafel图和电化学阻抗谱研究证实，BCE具有优异的电催化活性。人造MoS ₂基于/ SWCNH的DSSC表现出令人印象深刻的9.48％的光伏功率转换效率，高于具有含Pt CE的电池的性能（8.64％）。双层薄膜CE的简单而可靠的增长策略为制备经济高效的高性能催化BCE提供了一条新途径，以用于涉及无Pt DSSC的可再生能源应用。
