Synthesis and numerical simulation of formamidinium-based perovskite solar cells: a predictable device performance at NIS-Egypt.

Formamidinium lead triiodide (δ-FAPbI)-based perovskite solar cells showed remarkable potential as light harvesters for thin-film photovoltaics. Herein, the mechanochemical synthesis of δ-FAPbI, MAPbI, and mixed-cation FAMAPbI with (x = 0.3, 0.
