Universal Metal Electrode Contacts in Perovskite Solar Cells via Fermi‐Level Pinning at Yb‐Doped n + Fullerene Interfaces

ABSTRACT Efficient electron extraction at the electron transport layer (ETL)/metal interface is critical for high‐performance perovskite solar cells (PSCs), which is fundamentally governed by interfacial energy‐level alignment; however, the microscopic mechanism by which low‐resi...
