Homogeneous crystallization via sustained solvent-extraction channels for methylammonium-free all-perovskite tandem solar cells

Abstract Replacing volatile methylammonium (MA+) with formamidinium (FA+) or cesium (Cs+) cations in mixed Pb-Sn perovskite compositions improves thermal resilience. Nevertheless, the low-solubility Cs-based perovskite tends to preferentially crystallize into a dense Cs-rich surface layer during the...
