“…However, adding TMSs to the active layer enhanced the absorption prole of the blends, with the maximum peaks located at distinct wavelengths (320, 630, and 820 nm), which can be ascribed to the light scattering of the TMS nanostructures. 35,36 The relatively enhanced absorption of the TMS-containing active layers can help improve the current densities of the OPVs, which will be discussed later.…”

“…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%).

“…Ternary transition metal sulfides are a diverse group of functional materials with promising properties. [1][2][3][4] Compared to their oxide counterparts, these sulfides exhibit greater covalency and atomic overlap due to the diffuse nature of sulfur's orbitals, which is, in part, attributed to its lower electronegativity. 5 This leads to complementary properties, such as increased hole mobility and smaller electronic band gaps, making transition metal sulfides attractive candidates for p-type semiconductors, thermoelectric materials, and photovoltaics.…”
