The development of efficient and cost-effective dye-sensitized solar cells is crucial for advancing third-generation solar technology. Despite their advantages, dye-sensitized solar cells face challenges due to the high cost of platinum-based counter electrodes, which impedes their commercialization. MXenes and MXene-based composites have emerged as promising alternatives, offering exceptional electrochemical properties, high catalytic activity, and large surface area. This review examines the potential of MXenes in enhancing dye-sensitized solar cells’ performance. The findings suggest that Ti3C2Tx MXene exhibits remarkable electron transfer efficiency, making it a viable substitute for platinum. Additionally, composites, such as Ti3C2Tx with graphene, demonstrate superior electrical conductivity and catalytic activity, outperforming both pure MXene and graphene electrodes. The key performance metrics include cathodic peak current density, fill factor, short-circuit current, and charge transfer resistance, indicating that MXenes can match or exceed traditional materials. The Ti3C2Tx/graphene composite is recommended for its enhanced properties and cost-effectiveness.
