• Universal Metal Electrode Contacts in Perovskite Solar Cells via Fermi‐Level Pinning at Yb‐Doped n + Fullerene Interfaces (2026) · Advanced Functional Materials · doi

  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‐resistance contacts are established at fullerene/metal interfaces remains poorly understood.

• Boosting Efficiency and Stability of NiOx‐Based Inverted Perovskite Solar Cells Through D–A Type Semiconductor Interface Modulation (2024) · Advanced Functional Materials · cited 54× · doi

  Abstract NiOx is one of the promising inorganic hole transporting materials in inverted perovskite solar cells (PSCs), however, its device efficiency and stability are still limited by the energy level mismatch, low intrinsic conductivity, high interface defect density, and complex active species.
