Perovskite-based solar cells provide exceptional efficiency, but optimizing their performance requires precise control over material preparation methods. In this study, the authors use a hot-drop casting technique to fabricate 2D layered Ruddlesden-Popper perovskites and investigate exciton energy funneling dynamics through two-dimensional electronic and transient-grating spectroscopy.
