NMI was employed as an additive to slow down the crystallization and thus drive the formation of CsxFA1-xPbI3 with micrometer grain size, which probably facilitate the charge dissociation and transportation in photovoltaic devices. More importantly, composition dependent phase-segregation has been ...
In this work, based on a precise ion-exchange reaction at the grain surface, we fabricate a Cs0.15FA0.85PbI3/CsxFA1-xPbI3 heterostructure with a Cs-rich CsxFA1-xPbI3 quasi-shell structure. The Cs-rich inorganic structure on the perovskite surface increases defect formation energy and reduces ...
