The current work involves the fabrication of a MXene-Polythiophene (Ti<sub>3</sub>C<sub>2</sub>T <sub><i>x</i></sub> -PTh) composite <i>via</i> interfacial polymerization, alongside its deployment as a counter electrode (CE) or photocathode in dye-sensitized solar cells (DSSCs). The structural properties of the synthesized materials were investigated through a comprehensive array of techniques, including X-ray diffraction (XRD), fourier-transform infrared (FT-IR) spectroscopy, high resolution scanning electron microscopy (HRSEM), energy-dispersive X-ray analysis (EDAX), and X-ray photoelectron spectroscopy (XPS). The electrochemical performance, assessed <i>via</i> cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), revealed that the Ti<sub>3</sub>C<sub>2</sub>T <sub><i>x</i></sub> -PTh CE exhibits superior electro-catalytic activity, and reduction in charge transfer resistance compared to other individual CEs. These observations are in concordance with the data obtained from Tafel analysis. The incorporation of Ti<sub>3</sub>C<sub>2</sub>T <sub><i>x</i></sub> sheets into the composite significantly augmented its catalytic efficacy for triiodide reduction, manifesting in elevated short-circuit photocurrent density and enhanced fill factor metrics. A DSSC utilizing the Ti<sub>3</sub>C<sub>2</sub>T <sub><i>x</i></sub> -PTh CE exhibited a power conversion efficiency (PCE) of 5.83%, which stands on par with that of traditional Pt CEs. Thus, the Ti<sub>3</sub>C<sub>2</sub>T <sub><i>x</i></sub> -PTh CE material is posited as a viable, cost-efficient alternative to Pt, heralding a new era in the engineering of counter electrodes for the next generation of DSSCs.
