Mitigating low-dimensional phases and defects with methylammonium chloride in high-performance Dion–Jacobson quasi-2D tin perovskite solar cells with power conversion efficiency over 6%
Methylammonium chloride (MACl) enhances the performance of Dion-Jacobson quasi-2D tin perovskite solar cells by suppressing low-dimensional phases and defects. The addition of an optimal amount of MACl (20 mol%) improves the crystallinity, film morphology, and charge transport of the quasi-2D tin perovskite layer and enhances the power conversion efficiency (PCE) from 2.9% to 6.2%.
