Abstract
- 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 MAPbI 3 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. [Display omitted] • Polyurethane with disulfide bonds achieve the self-healing flexible perovskite solar cells by the phase-locked dynamic bonds. • The dynamic bonds of PUDS transform to the phase-locked state strengthening the self-healed perovskite film. • The efficiency of the cracked FPSC recovers from 12% (Broken: 2.06%) to 88% (Recovery: 15.12%) of the initial efficiency (17.19%) after the multiple bending-heal. • The FPSC with PUDS maintains 84% of the initial PCE after 4000 bending cycles at the radius of 3 mm.
