Lead-free perovskite solar cells with hybrid tin halides (Sn-PVKs) as harvesters have attracted attention respect to eliminating the contamination of conventional lead halides. However, Sn-PVK films usually inferior performance due rapid crystallization and uncontrollable morphology. Moreover, Sn2+ ions suffer from irreversible oxidation that results in self-doping device instability. Additive engineering is a key strategy for improving quality films, but solid residues additives could degrade transport–recombination process. In this work, dipropyl sulfide (DPS) was introduced volatile additive into precursor solution, no residue exists after thermal annealing. The coordinating ability DPS molecules stabilized form intermediate complex, which retards films. Consequently, power conversion efficiencies devices increase 11.0% 12.9% less recombination lower leakage current, stability improved simultaneously.

Identifying Rare Events in Quantum Molecular Dynamics of Nanomaterials with Outlier Detection Indices

The Journal of Physical Chemistry Letters, Год журнала: 2024, Номер 15(41), С. 10384 - 10391

Nanoscale and condensed matter systems evolve on multiple length- time-scales, rare events such as local phase transformation, ion segregation, defect migration, interface reconstruction, grain boundary sliding can have a profound influence material properties. We demonstrate how outlier detection indices be used to identify in machine-learning based, high-dimensional molecular dynamics (MD) simulations. Designed order data-points from typical untypical, the enable one capture atomic that are hard detect otherwise. approach with nanosecond MD simulation of metal halide perovskite is extensively studied for solar energy optoelectronic applications. The method captures initial spontaneous fluctuation half later, both giving rise persistent deep electronic trap states impact charge carrier lifetime transport performance. offers generalizable simple identifying complex matter, molecular, nanoscale systems.
