Multiple‐Active‐Site Additives Enable Synergistic Surface Passivation and Defect Healing for High‐Efficiency and Durable Inverted Perovskite Solar Cells
Crystal quality is essential for high‐performance and stable perovskite solar cells (PSCs). Surface and grain‐boundary defects can induce non‐radiative recombination, while water molecules and high temperatures can degrade perovskite and shorten device lifetime. Dual strategies of defect passivation and interfacial...
