Spatial Atomic Arrangement of Cyclohexyl-Based Ligands for Enhanced Interface Passivation in 2D/3D Perovskite Solar Cells.

ABSTRACT: Metal halide perovskite solar cells (PSC) have emerged as a promising candidate for next-generation photovoltaic technologies, achieving remarkable power conversion efficiencies (PCE) in polycrystalline thin-films. Nonetheless, their PCE and long-term stability are often limited by a high density of defects at interfaces and grain boundaries. One effective strategy to mitigate these issues is forming 2D/3D heterojunction structure by introducing a surface-passivating interfacial layer of quasi-2D Ruddlesden-Popper perovskite (RPP) with various functional ligand molecules. In this study, hydroxyl-functionalized cyclohexyl ammonium hydrochloride (ACHACl) is employed as the ligand molecule, which features dual functional groups. A comparative analysis reveals that cis-configurations of the li
