2D Phase Formation on 3D Perovskite: Insights from Molecular Stiffness.
ACS Appl Mater Interfaces
September 2024
Several studies have demonstrated that low-dimensional structures (., two-dimensional (2D)) associated with three-dimensional (3D) perovskite films enhance the efficiency and stability of perovskite solar cells. Here, we aim to track the formation sites of the 2D phase on top of the 3D perovskite and to establish correlations between molecular stiffness and steric hindrance of the organic cations and their influence on the formation and crystallization of 2D/3D.
