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.
