Abstract Lead halide perovskite solar cells (PSCs) have demonstrated power conversion efficiencies comparable to silicon‐based cells, yet their instability under environmental stressors, such as humidity, heat, and light, remains a significant barrier commercialization. A primary cause of this is the uncoordinated lead ions (Pb 2+ ), which accelerates degradation PSCs pose concerns due potential leakage. Recently, introduction ligands into has shown promise in mitigating toxicity through effective passivation, primarily by forming hydrogen bonds (H‐bonds) between functional groups structure. In minireview, we explore critical role H‐bonds stabilizing enhancing structural integrity layer reducing Furthermore, discuss contribution these defect hydrophobicity, self‐encapsulation, cross‐linking, self‐healing mechanisms. These insights will highlight multi‐functional capabilities improving long‐term stability durability PSCs, offering pathways address current challenges
