Abstract:Understanding the effects of process variables on the large-scale manufacturing of lead halide perovskite solar cells (PSCs) is crucial for their commercialization. In this study, we conducted a comparative analysis of four bar (blade) coating methods, along with thermal annealing or hot airflow, for two-dimensional (2D) Ruddlesden−Popper PSCs in the presence of ammonium chloride (NH 4 Cl) and potassium chloride (KCl) additives. Intriguingly, the anisotropic charge carrier mobilities evaluated via time-resolve… Show more
