The performance and stability of metal halide perovskite solar cells strongly depend on precursor materials and deposition methods adopted during the perovskite layer preparation. There are often a number of different formation pathways available when preparing perovskite films. Since the precise pathway and intermediary mechanisms affect the resulting properties of the cells, studies have been conducted to unravel the mechanisms involved in the formation and evolution of perovskite phases.

- - The study finds that using an organic molecule with two anilinium cations enhances the efficiency and stability of perovskite solar cells when applied as a passivation layer.
- - Comparing this molecule to its neutral form reveals that the alteration in electron density due to protonation and the presence of a halide anion contributes to improved passivation.
- - The research also highlights the important role of the counteranion in influencing the solar cell's overall performance.
