Enhancing the Oxygen Evolution Performance by Introducing NiO‐Supported Mesoporous Titanium Dioxide

open access: yesChemistryOpen, EarlyView.
Herein, a schematic representation of the synthesis of NiO‐supported mesoporous TiO2 is reported. The process involves self‐assembly of polyvinylpyrrolidone (PVP), Ti(acac)2, nickel salt, and ethanol, followed by solvent evaporation, thermal polymerization, and stepwise calcination under N2 (350 °C) and air (450 °C) to remove PVP and carbon, yielding ...

Exploring the Impedance Spectroscopy in Hole‐Conductor‐Free Mesoscopic Perovskite Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study employs impedance spectroscopy (IS) to investigate the carrier dynamics of printable perovskite solar cells (p‐MPSCs). The exceptional stability of p‐MPSCs enables reliable IS measurements under various conditions. We develop an equivalent circuit model to analyze the IS data, linking each circuit element to specific dynamic processes.
