Binary cations minimize energy loss in the wide-band-gap perovskite toward efficient all-perovskite …
We propose a synergy of nonpolar and polar ligands to enhance defect passivation and align interfacial energy levels by establishing a dipole layer. Initially, as illustrated in Figure 1 A, we investigate the impact of surface treatment on perovskite films with various spacer cations by assessing PLQY (note: detailed calculations are elucidated …
