“…Despite these features, Pt is scarce and expensive, making it unfavorable for large-scale commercial manufacturing. Furthermore, Pt is prone to corrosion in iodide-based electrolytes, leading to PtI 4 . , Extensive research to replace Pt as a CE has been conducted on various classes of materials; among these, carbonaceous materials (two-dimensional graphene, carbon black, and CNTs), , transition metal dichalcogenides (MoS 2 , SnS 2 , WSe 2 , and others), carbon–metal composites, , metal oxides (NiO, V 2 O 5 , and MoO 3 ), , and conductive polymer composites , were evaluated. In another approach, CuS/Graphene heterostructured nanocomposites were utilized as CE in DSSC.…”

In this work, we report the first single-step, size-controlled synthesis of Cu 3 VSe 4 cuboidal nanocrystals, with the longest dimension ranging from 9 to 36 nm, and their use in replacing the platinum counter electrode in dye-sensitized solar cells. Cu 3 VSe 4 , a ternary semiconductor from the class of sulvanites, is theoretically predicted to have good hole mobility, making it a promising candidate for charge transport in solar photovoltaic devices. The identity and crystalline purity of the Cu 3 VSe 4 nanocrystals were validated by X-ray powder diffraction (XRD) and Raman spectroscopy. The particle size was determined from the XRD data using the Williamson−Hall equation and was found in agreement with the transmission electron microscopy imaging. Based on the electrochemical activity of the Cu 3 VSe 4 nanocrystals, studied by cyclic voltammetry, the nanomaterials were further employed for fabricating counter electrodes (CEs) in Pt-free dye-sensitized solar cells. The counter electrodes were prepared from Cu 3 VSe 4 nanocrystals as thin films, and the charge transfer kinetics were studied by electrochemical impedance spectroscopy. The work demonstrates that Cu 3 VSe 4 counter electrodes successfully replace platinum in DSSCs. CEs fabricated with the Cu 3 VSe 4 nanocrystals having an average particle size of 31.6 nm outperformed Pt, leading to DSSCs with the highest power conversion efficiency (5.93%) when compared with those fabricated with the Pt CE (5.85%).
