Abstract Managing residual stress in hybrid perovskites is crucial for achieving mechanically stable perovskite solar cells (PSCs) with high power conversion efficiency (PCE), while challenges remain synchronous regulation multiple dimensions during solution‐processing. Herein, a grain‐boundary‐lubricating strategy demonstrated to relieve within films—both in‐plane and out‐of‐plane—for enhancing the mechanical integrity of PSCs. As proof concept, laser‐manufactured multilayer nanolubricants WSe 2 are embedded at grain boundaries (GBs) films, linking adjacent grains through interactions between uncoordinated Pb active Se atoms. This multi‐dimensional release significantly reduces concentration GBs, shifting fracture mode films from intergranular transgranular, thereby improving reliability PSCs under external stress. Such also facilitates charge transport rationally selected nanolubricant can passivate interfacial defects. The resultant deliver PCEs over 25% pronounced environmental stability, demonstrate exceptional durability, retaining 88.3% their initial PCE even after 10 000 bending cycles radius 3 mm. work opens new avenue management via embedding nanolubricants.

Despite the fact that perovskite solar cells (PSCs) are widely popular due to their superb power conversion efficiency (PCE), further applications still restricted by low stability and high-density defects. Especially, weak binding ion–electron properties of crystals make them susceptible moisture attack under environmental stress. Herein, we report an overall sulfidation strategy via introduction 1-pentanethiol (PT) into film inhibit bulk defects stabilize Pb ions. It has been confirmed thiol groups in PT can uncoordinated ions passivate iodine vacancy forming strong Pb–S bonds, thus reducing nonradiative recombination. Moreover, favorable passivation process also optimizes energy-level arrangement, induces better crystallization, enhances charge extraction full cells. Consequently, PT-modified inverted device delivers a champion PCE 22.46%, which is superior control (20.21%). More importantly, retains 91.5% its initial after storage air for 1600 h over 85% heating at 85 °C 800 h.
