Abstract

Many materials have been explored as a counter electrode material to replace platinum electrode in dye-sensitized solar cells (DSSCs). In this work, CoxSy/NixSy/MoxSycomposites at two different compositions, namely, CNM10, CNM25 were synthesizedviahydrothermal method. The XRD, FE-SEM, and EDX analysis of the samples confirmed the formation of CNM10 and CNM25 composites. The cyclic voltammetry (CV) study of CNM10 and CNM25 electrodes showed faster triiodide ion reduction at the electrode/electrolyte interface than the Pt electrode. The electrochemical impedance spectroscopy studies of CNM10 and CNM25 electrodes showed lowerRCTvalues for both CNM10 and CNM25 electrodes than that of a Pt electr..
