Self‐healing polyurethane with dynamic oxime–carbamate bonds has been incorporated into perovskite films, as reported by X. Hu, F. Li, Y. Chen, and co‐workers in their Research Article on page 16602. The polyurethane additive releases mechanical stress and repairs cracks at the grain boundaries. This growth strategy for crystalline semiconductors resembles a broken mirror joined together and enables a new approach for the development of flexible and stretchable electronics.
