Pb leakage from damaged perovskite solar cells exposed to water is minimized by applying a TiO2 sponge to sequester Pb ions. The sponge can be deposited on ready-to-use devices using a scalable and solvent-free process. As TiO2 is already used in perovskite solar cells, this approach promises environmental benefits without substantial investment costs.
