Dye-sensitized solar cells based on highly catalytic CNTs/Ti₃C₂T_x MXenes composite counter electrode.

ABSTRACT: Establishing stable and efficient Pt-free counter electrodes (CEs) is an important challenge for dye-sensitized solar cells (DSSCs). Ti₃C₂T_x MXene, with its high catalytic activity and conductivity, has gained attention as a CE in DSSCs. The focus of this paper is on the preparation of Ti₃C₂T_x decorated carbon nanotubes (CNTs) composite electrode materials (CNTs/Ti₃C₂T_x), and testing their performance as CEs in DSSCs. Through a series of electrochemical tests, a CNTs/Ti₃C₂T_x CE exhibits good electrocatalytic activity toward iodine-based electrolytes with low charge transfer resistance, which is close to the performance of a Pt CE.
