Published in 2024 at "Advanced Energy Materials"

DOI: 10.1002/aenm.202401303

Abstract: 2D Ruddlesden‐Popper perovskites (RPP) with formamidinium‐cesium (FAC) alloyed cations possess powerful thermal‐moisture stability. However, their photovoltaic performance is hindered by the elusive spatial heterogeneity at multiscale lengths, highly associated with their coupled charge selective contacts.… read more here.
