“…Since CE regenerates the redox couple, Pt-based electrodes are being extensively used as they have excellent corrosion stability against the iodine electrolyte, thereby delivering higher PCE. , The higher cost of Pt forces the researchers to find alternative materials for CE. Few CE materials with high PCE have already been reported which include transition metal nitrides, , chalcogenides, , inorganic materials, and carbon-based materials. − Among them, the transition metal sulfides have received more attention because of their conductivity, shallow bandgap and band position, strong quantum size effect, and small effective mass, , which are useful in the field of energy conversion and energy storage devices. − For example, Gurulakshmi et al prepared an MoS 2 through the electrodeposition method and employed it as a CE for DSSC, reporting a PCE of 4.84% . Xianqing Liu et al have synthesized VS 2 nanofibers by a in situ hydrothermal method and observed a PCE of 6.24%, which is compared with the Pt CE cell (6.44%) .…”
