Crystallization and Interfacial Regulation of CsPbI3 Perovskites by Dimethylammonium Chloride for Efficient and Stable Solar Cells
All-inorganic CsPbI3 perovskite solar cells (PSCs) are attractive for perovskite/silicon tandem solar cells because of their suitable bandgap and intrinsic thermal robustness, yet their power conversion efficiencies (PCEs) and long-term stability remain limited by defective film and interfaces. The existing additives o...
