buried interfaces are crucial for achieving efficient and stable perovskite solar cells (PSCs). However, studying and optimizing buried interfaces remains a challenging issue due to its non-exposed characteristics. Here, a simple and effective targeting strategy is proposed to regulate the NiOx/perovskite buried interface by passivating buried defects in perovskite and adjusting the growth of perovskite crystals through modifying multifunctional molecules (DTD) on the surface of NiOx. DTD has multifunctional targeting groups that enable it to interact strongly with both perovskite and NiOx simultaneously, thereby building a molecular bridge at the NiOx/perovskite buried interface, enabling high-quality upper perovskite films, excellent interface contact and more matched energy levels between perovskite and NiOx. As a result, the modification of DTD significantly improves the efficiency of perovskite devices from 22.19 % to 25.00 % (certified value of 24.12 %), along with excellent long-term and operational stability. This strategy provides a simple and effective targeted therapy for the buried interface in PSC, achieving high efficiency and stability.
