Bifunctional Tetramethylammonium Acetate Modifier Synchronizes Defect Passivation and Energy-Level Alignment for HTL-Free Carbon-Based Inorganic Perovskite Solar Cells

Abstract Carbon-based HTL-free CsPbI2.75Br0.25 all-inorganic perovskite solar cells face challenges from interfacial defects and suboptimal energy-level alignment. In this work, tetramethylammonium acetate (TMMAc) is employed for the first time as a multifunctional surface modifi...
