Herein, an FMS/CC composite was successfully fabricated by depositing FeMoS4 onto a pristine carbon fiber cloth (CC) substrate via a facile two-step hydrothermal method. The amorphous nature of the FMS/CC composite endows it with abundant catalytically active sites, thereby accelerating the reduction of I3-. More importantly, the dye-sensitized solar cells (DSSCs) prepared by scraping it on flexible titanium mesh with low resistance had low series resistance (Rs). Electrochemical characterizations revealed that the DSSCs employing the FMS/CC counter electrode achieved a power conversion efficiency (PCE) of ca. 9.51% (surpassing the ca. 8.15% efficiency of the Pt counter electrode), open-circuit voltage (Voc) of ca. 0.79 V, short-circuit current density (Jsc) of ca. 18.31 mA·cm-2, and fill factor (FF) of ca. 0.65. Moreover, after 100 times of cyclic voltammetry (CV) test, the CV curve remainedunchanged, indicating the excellent stability of FMS/CC in the electrolyte containing I3-/I-.
