Designing Multifunctional Co and Fe Co-Doped MoS₂ Nanocube Electrodes for Dye-Sensitized Solar Cells, Perovskite Solar Cells, and a Supercapacitor.

ABSTRACT: In the present study, three types of specific solid, core-shell, and hollow structured cobalt and iron co-doped MoS₂ nanocubes (denoted as s-Co-Fe-MoS _x , c-Co-Fe-MoS _x , and h-Co-Fe-MoS _x ) are controllably synthesized for the first time by regulating the reactant mass ratios. The prepared Co-Fe-MoS _x nanocubes can function as a counter electrode in dye-sensitized and perovskite solar cells (DSCs and PSCs) and a working electrode in a supercapacitor. In the DSC system, the c-Co-Fe-MoS _x nanocubes exhibit the maximum catalytic activity to the Co^3+/2+ redox couple regeneration, and the device achieves a power conversion efficiency (PCE) of 8.69%, significantly higher than the devi
