Coordination‐Driven Neutralization of SnO 2 Colloids for Suppressing Buried Interfacial Deprotonation in Perovskite Solar Cells

ABSTRACT Commercial SnO 2 colloidal solutions are widely used as an electron transport layer (ETL) in perovskite solar cells (PSCs). However, their intrinsic strong alkalinity, required for colloidal stability, creates a high proton‐affinity SnO 2 /perovskite interface that promo...
