Abstract
Abstract Nickel oxide (NiO x ) is considered as a potential hole transport material in the fabrication of lead‐tin (Pb‐Sn) perovskite solar cells (PSCs) for tandem applications. However, the energy level mismatch and unfavorable redox reactions between Ni ≥3+ species and Sn 2+ at the NiO x /perovskite interface pose challenges. Herein, high‐performance Pb‐Sn‐based inorganic PSCs are demonstrated by modulating the NiO x /perovskite interface with a multifunctional 4‐aminobenzenesulfonic acid (4‐ABSA) interlayer. The 4‐ABSA interlayer induces the formation of an oriented dipole moment directed from NiO x to perovskite, effectively elevating the valance band maximum of the NiO x film, thus balancing the energy…
