Halide-Cation Interactions Enable Controlled Crystallization and Defect Minimization in High-Performance All-Perovskite Tandems
{{output}}
This work demonstrates that synergistic passivation using Cl-salt or F-salt significantly enhances the performance of wide-bandgap (WBG) perovskite subcells and all-perovskite tandem solar cells (TSCs). The improved performance is attributed to the dual mechan... ...
