Structural Refinement and Optoelectrical Properties of NdRuO and GdRuO Pyrochlore Oxides for Photovoltaic Applications.

High-performance photovoltaic devices require active photoanodes with superior optoelectric properties. In this study, we synthesized neodymium ruthenate, NdRuO (NRO), and gadolinium ruthenate pyrochlore oxides, GdRuO (GRO), via the solid-state reaction technique, showcasing their potential as promising candidates for photoanode absorbers to enhance the efficiency of dye-sensitized solar cells. A structural analysis revealed predominantly cubic symmetry phases for both materials within the - space group, along with residual orthorhombic symmetry phases (NdRuO and GdRuO, respectively) refined in the space group.
