Abstract

A Pt-free ternary nickel copper sulfide (NCS) electrocatalyst for iodide / triiodide electrolyte reduction in dye-sensitized solar cells was studied. The electrocatalyst was prepared via hydrothermal method and characterized by X-ray Diffraction, Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy and X-ray Photoelectron Spectroscopy. XRD analysis showed corresponding signals of NiS₂ and CuS. Cyclic voltammetry analysis demonstrated fast reduction of triiodide by NCS electrocatalyst. Electrochemical impedance analysis revealed comparable electrocatalytic activity of NCS to that of Pt, wherein NCS-based solar cell produced 7.66 % efficiency compared to 8.11% for Pt DSSC.
