Comparison of Dynamical Behaviour in MAPbX3 and FAPbX3: How Do They Differ ?

Abstract: Organic-inorganic lead halide perovskite compounds are shown to be very promising candidates for low cost, solution-processable, highly efficient (>22%) solar cells with a short energy payback time. The interesting feature of these materials is the presence of an organic molecular ion at the A site of the ABX3 structure. Many of the remarkable properties of the halide perovskites have been attributed to the dipolar nature and the dynamic behaviour of these cations. Therefore dynamics of molecular motion is an important prerequisite for mechanistic explanations of the outstanding optoelectronic properties of these systems. Methylammonium lead hallide (MAPbX3) and formamidinium lead hallide (FAPbX3), X=I, Br, Cl, has been the subject of great interest. We would like to investigate the dynamical behaviour of these systems using quasielastic neutron scattering technique.
