Abstract
Novel barium based oxynitride perovskites (BaCuO2N, BaCoO2N and bimetallic BaCu0.5Co0.5O2N) were successfully synthesized by a cost-effective sol-gel method. The XRD patterns were indexed to a triclinic crystal system for the single-metal compositions, whereas the mixed Cu–Co composition was indexed to a monoclinic system. FESEM and AFM analyses revealed nanoscale grains with distinct surface morphologies, while optical characterization showed broad absorption across the UV-visible region. Thermal analysis indicated that the major mass-loss events occurred below approximately 350 ºC. The investigated materials exhibited p-type semiconducting behaviour. Among the studied compositions, BaCoO2N showed the highest measured power conversion efficiency (PCE) of 15.77%, compared with 10.60% for BaCuO2N and 10.86% for BaCu0.5Co0.5O2N under the applied measurement conditions. The higher PCE of BaCoO2N suggests that its composition and associated structural and optoelectronic characteristics may be favourable for photovoltaic performance.
