Perovskite solar cells adopting a layer of various nanocrystals (NCs) on top of perovskite film exhibit similar enhancement of the photovoltaic (PV) properties regardless of the kind of NC material, even though NC materials possess different electrical and optical properties. In this paper, we reveal that the key reason for the enhanced PV performance is the surface passivation effect of the perovskite film by oleylamine ligands of NCs.
