From Precursor to Performance: The Impact of FAI Impurities on Halide Perovskite Thin-films and Devices

Key Points

The central aim is to investigate how FAI impurities impact the performance and stability of metal halide perovskite thin-films and devices.
Analyses of power conversion efficiencies of perovskite solar cells
Stability testing of thin-film devices under various conditions
Comparison of performance metrics with and without FAI impurities
FAI impurities negatively affect long-term stability of perovskite devices
Devices with reduced impurities showed improved efficiency
Higher power conversion efficiencies correlate with lower impurity levels

Abstract

While metal halide perovskites have shown remarkable power conversion efficiencies in photovoltaic applications, uncertainty concerning their long-term stability remains a significant barrier to widespread deployment. Previous studies have demonstrated that...
