In present study, Cu2S nanoparticles (NPs) and ZnO nanorods (NRs) were synthesized using chemical methodsand applied in photoelectrochemical cells as an electrode material. The X-ray diffraction spectrums were applied forconfirming the respective crystal structures which further were supported by energy dispersive X-ray analysis mappingswhere elemental composition proportions, as expected, are obtained. From Raman spectroscopy patterns revealedchemical bonds for Cu2S coated ZnO. Surface morphologies were noticed from the field-emission scanning electronmicroscopy digital images. By UV-Vis spectroscopy analysis, optical band gap of ZnO decreased from 3.205 eV to 2.78eV for Cu2S-ZnO. The power conversion efficiency () of Cu2S-ZnO electrode was 0.160% which was 0.07% for ZnO.This increment was assigned to the decrease of the charge transport resistance from 95 to 79 in electrochemicalimpedance spectroscopy measurement.
