ABSTRACT A new quaternary oxide, Ca2MoCu3O8, has been synthesized using solid state reaction between corresponding oxides and characterized by chemical analysis, X- ray diffraction, electrical conductivity. It crystallizes in a tetragonal structure with a lattice parameter ao = 10.624 A0 and co = 6.208 A0. It is an n-type semiconductor and conducts current via different mechanism in two temperature ranges. A break is found in the plot of Log σ vs 1/T at 391 k when activation energy changes from 0.269 to 1.366 eV. The photoelectrochemical properties are reported. The material in the form of Hydrogen annealed pellet was used as photoanode in electrochemical photovoltaic (ECPV) cell. The Flat band potential was located at -0.42V. PEC cell parameters such as Conversion Efficiency( η) and Fill Factor have been determined as 0.157% and 0.267 respectively. Keywords: Synthesis, chemical analysis, X-ray diffraction; Electrical conductivity and Photoelectrochemical (PEC) study.
