Synthesis of Cobalt Oxide Solar Cell

Abstract

In this paper, we report the successful synthesis of cobalt oxide solar cell and characterized a high-efficiency cobalt oxide (Co₃O₄) solar cell. The solar cell was constructed using the spin coating technique with a power conversion efficiency of 18.71% under 1-sun illumination (100 mW/cm²), with an open-circuit voltage (V_oc) of 0.544 V and a short-circuit current density (J_sc) of 151.21 mA/cm². These results highlight the potential of using readily available materials and simple deposition techniques to achieve efficient Co₃O₄-based solar cells.
