Subjects Solar cells Abstract Annealing, while indispensable for achieving high-quality perovskite crystals, introduces strain into the material, undermining the stability of perovskite solar cells. Here we incorporate 1,4-butanesultam as an additive into the perovskite precursor film to address this issue. During annealing, the additive liquifies and promotes grain boundary reconstruction and crystal reorganization, resulting in large, strain-free perovskite grains. The liquid state also facilitates the conformal deposition of the self-assembled molecules that serve as a hole transport layer at the bottom surface of the perovskite, further minimizing tensile strain. The resulting solar cell achieves a power conversion efficiency of 26.79% and retains 95% of its initial efficiency after 1,000 h of ISOS-V-2 testing, as well as 98% after 1,500 h of diurnal cycling between dark at 20 °C and light at 85 °C.
