Compositionally-tunable mechanochemical synthesis of ZnxCo3−xO4 nanoparticles for mesoporous p-type photocathodes

Abstract

A solid-state mechanochemical synthesis of ZnxCo3−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.
