Enhanced Synergetic Catalytic Effect of Mo2C/NCNTs@Co Heterostructures in Dye-Sensitized Solar Cells: Fine-Tuned Energy Level Alignment and Efficient Charge Transfer Behavior

“…However, its high price, limited reserves and insufficient anticorrosion in I – /I 3 – electrolyte restricted its practical application in DSSCs . The persistent pursuit for commercialization of DSSCs stimulated significant research efforts to exploit new CE materials for replacing Pt, such as carbonaceous materials (carbon black, graphite, graphene, carbon nanofiber, carbon nanotubes, porous carbon), , alloys, , transition metal compounds (carbides, nitrides, oxides, sulfides, and selenides), , conductive polymers (polyaniline, poly­(3,4-ethylenedioxythiophene)), , and their composites. − Unfortunately, the present Pt-free CEs generally exhibited inferior electrocatalytic activities to the state-of-the-art Pt. Thus, the development of highly active Pt-free CEs still relies on the rational engineering of new-structured materials with advanced structural and electronic properties for boosting their electrocatalytic activity, which remains a crucial challenge.…”
