Investigation of Lithium Iodide Intercalated X/S2 nanosheets for DSSC Applications

Abstract

In the realm of solar energy conversion, dye sensitized solar cells (DSSCs) are gaining prominence. Typically, an anode and a cathode are required to manufacture an FTO-based device; the anode materials of the current study are TiO₂ and a high focus is given to creating cathode materials that are WS₂ and MOS₂ in place of alternative platinum (Pt). Pt is well recognized for its high cost and scarcity. In this study, a low-cost Pt-Free counter electrode was employed and determined solar cell efficiency of 2.52% over a long length of time. Further research on (X/S₂) WS₂/MoS₂ nanoparticles reveals increased solar efficiency. The acquired X/S₂ nano layer has a shape that has been validated using a transmission electron microscope. Furthermore, the structural, optical, and functional groups of materials were described, and the probable mechanisms were examined.
