Nano-size nature of the $\alpha$-FAPbI${}_3$ by means of large-scale ab initio simulations

Virginia Carnevali, Lorenzo Agosta, Vladislav Slama +3

Formamidinium-lead-iodide (FAPbI${}_3$) has established itself as the state of the art for high solar-energy conversion efficiency in perovskite-based solar cells. At room temperatur…
