Abstract

The cubic (α-) phase stabilization of FAPbI₃ is of high interest owing to its ideal 1.48 eV band gap. However, controlled incorporation of formamidinium iodide (FAI) in the film and formation of the non-photoactive phase (δ-FAPbI₃) are challenges of co-evaporated films. This preview highlights two recent works, where interfacial phosphonic acid functional groups enable controlled FAI incorporation and α-FAPbI₃ stabilization of co-evaporated perovskite films.

立方体 FAPbI3 的生长和稳定：膦酸与共蒸发过氧化物之间的相互作用

由于 FAPbI3 理想的带隙为 1.48 eV，因此其立方（α-）相的稳定性备受关注。然而，薄膜中碘化甲脒 (FAI) 的可控掺入以及非光电活性相（δ-FAPbI3）的形成是共蒸发薄膜所面临的挑战。本预览重点介绍了最近的两项研究成果，在这两项研究中，界面膦酸官能团实现了共蒸发过氧化物薄膜中可控的碘化酰胺（FAI）掺入和α-FAPbI3 稳定化。
