This paper discusses the improvement of FASnI3 perovskite solar cells' reproducibility and stability by incorporating 4F-PHCl, a reductive molecule, in the perovskite precursor solution. 4F-PHCl enhances the solution's stability, prevents Sn2+ oxidation, and improves the films' crystallinity and stoichiometry, resulting in a power conversion efficiency of 10.86%.
How Paios was used
PAIOS was used to measure transient photovoltage and photocurrent decays, shedding light on charge carrier dynamics and demonstrating improved charge transport and reduced recombination in 4F-PHCl-treated devices.
