Discovery of electrode materials with superior light harvesting performance with high conductivity nature have become more and more urgent for the eld of photovoltaics and portable electronic devices. Here in, synthesis of Fe 2 (MoO 4 ) 3 /reduced graphene oxide (RGO) nanocomposite was prepared by simple hydrothermal approach and used as high e cient dye sensitized solar cells (DSSCs). The decoration of RGO into the Fe 2 (MoO 4 ) 3 was proved by various physic-chemical studies such as XRD, SEM, TEM, Raman, UV, PL and BET analysis. Due to the synergic effect between the Fe 2 (MoO 4 ) 3 and RGO the light absorption property is signi cantly improved as well the high surface area (112.5 m 2 /g) and pore size (38.7 nm) was achieved than compared with bare Fe 2 (MoO 4 ) 3 (88.5 m 2 /g and 17.8 nm). The Fe 2 (MoO 4 ) 3 /RGO hybrid photoanode establish to display an outstanding catalytic activity toward the reduction of triiodide to iodide in a dye-sensitized solar cell (DSSC) and can provide a solar cell e ciency of 9.65%, which is superior to a Pt-based DSSC (6.17%). The better electro-catalytic ability of Fe 2 (MoO 4 ) 3 /RGO electrode is obtained by a synergistic effect that resulted in the high speci c surface area and intrinsic reactivity of the photocathode materials.
