The brittleness of perovskite (PVK) film restrains the development and application of the flexible perovskite solar cells (FPSCs). We utilize the polyurethane elastomers with disulfide bonds (PUDS) as a self-healing polymer to construct self-healing FPSCs and strengthen the self-healed perovskite film by the phase-locked state. The PUDS efficiently enhances the flexibility and self-healing properties of FPSCs. The champion efficiencies of MAPbI₃ on rigid and flexible substrates with PUDS are 20.30% and 17.19%, respectively. Importantly, the efficiency of cracked FPSC after thermal self-healing (80 °C) has been recovered from 12% (Broken: 2.06%) of the initial efficiency (17.19%) to 88% (Recovery: 15.12%). Besides, the efficiency of FPSC with PUDS maintains 95% of the initial value after 3000 h stored in glove box. This strategy provides an effective approach for developing flexible electronics.

钙钛矿（PVK）薄膜的脆性限制了柔性钙钛矿太阳能电池（FPSCs）的发展和应用。我们利用具有二硫键的聚氨酯弹性体 (PUDS) 作为自修复聚合物来构建自修复 FPSC，并通过锁相状态增强自修复钙钛矿薄膜。PUDS 有效地增强了 FPSC 的灵活性和自愈特性。MAPbI _{3的最高效率}在具有 PUDS 的刚性和柔性基板上，分别为 20.30% 和 17.19%。重要的是，热自愈（80°C）后裂解FPSC的效率已从初始效率（17.19%）的12%（破碎：2.06%）恢复到88%（回收率：15.12%）。此外，在手套箱中存放 3000 小时后，带有 PUDS 的 FPSC 的效率保持在初始值的 95%。该策略为开发柔性电子产品提供了有效途径。
