Entropy-driven structural transition and kinetic trapping in formamidinium lead iodide perovskite

A challenge of hybrid perovskite solar cells is device instability, which calls for an understanding of the perovskite structural stability and phase transitions. Using neutron diffraction and first-principles calculations on formamidinium lead iodide (FAPbI(3)), we show that the entropy contributio...
