Abstract

A solid-state mechanochemical synthesis of Zn_xCo_3-xO₄ was developed with highly tunable Zn concentration. Photovoltaic performance was evaluated in dye-sensitized solar cells and tested with various Zn concentrations, exhibiting maximum performance with ZnCo₂O₄. Oxidative treatments led to a nearly three-fold increase in dye loading and a significant increase in short-circuit current density.
