Intrinsic Interfacial Energy Alignment Enables ETL‐Free Organic Solar Cells
Advanced Functional Materials, EarlyView.Molecular orientation of the small‐molecule donor BTR‐Cl induces a vacuum‐level shift that pins the Fermi level at ∼4.4 eV at the active layer/Ag interface, enabling Ohmic contact formation without an electron transport layer. This strategy is extended to ternary PM6:Y6:BTR‐Cl devices, achieving an ETL‐free efficiency of 18.6% with enhanced operational
