2D Rhenium- and Niobium-Doped WSe₂ Photoactive Cathodes in Photo-Enhanced Hybrid Zn-Ion Capacitors.

ABSTRACT: Designing a multifunctional device that combines solar energy conversion and energy storage is an appealing and promising approach for the next generation of green power and sustainable society. In this work, we fabricated a single-piece device incorporating undoped WSe₂, Re- or Nb-doped WSe₂ photocathode, and zinc foil anode system enabling a light-assisted rechargeable aqueous zinc metal cell. Comparison of structural, optical, and photoelectric characteristics of undoped and doped WSe₂ has further confirmed that ionic insertion of donor metal (rhenium and niobium) plays an important role in enhancing photoelectrochemical energy storage properties. The electrochemical energy storage cell consisting of Re-doped WSe₂ (as the photoactive cathode a
