Layered 2D/3D perovskite bilayer heterostructures have the potential to boost the performance and durability of many types of electronic and photonic devices, but maintaining this performance depends on the stability of the cell’s 2D interlayer. In this study, researchers optimized time-resolved, spontaneous thin-film deposition of 2D perovskites using a mixed solvent approach to produce phase pure, stable thin films with high crystallinity.
