Perovskite solar cells with atomically coherent interlayers on SnO 2 electrodes. Our study provides a sustainable solution to one of the environmental and health risks of PSCs and would accelerate their practical applications. Further demonstration of the sponge application with desired thickness on ready-to-use devices, glass and polymeric foils enforces the practical value of the current approach. Already an essential material for PSCs, the additional use of TiO 2 through a scalable and solvent-free sputtering process promises extra cost benefits and higher sustainability. Here we show that Pb leakage can be prevented by applying a transparent titanium dioxide (TiO 2) sponge that allows for an efficient Pb sequestration of 58 ng cm −2 nm −1. However, one of the major barriers to its full commercialization is the presence of toxic lead (Pb), which enables the current record in photoconversion efficiency but risks being released into the environment when subjected to water or rain.
