Summary: Two typical 2D layered MXenes, Ti3C2 and V2C, were synthesized as counter electrode catalysts in dye-sensitized solar cells, with Ti3C2 demonstrating superior performance over V2C. By optimizing the etching time of Ti3C2 and postprocessing with KOH aqueous solutions, the power conversion efficiency of the device was significantly improved. The high catalytic behavior of Ti3C2 is attributed to its 2D layer structure, making it a potential candidate as a noble metal electrode alternative.
