N2 - 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.
