Static/dynamic disorder, ion migration and possible ferroelectricity in the hybrid halide perovskite CH3NH3PbI3 for PV applications

Abstract: Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this class is the methyl-ammonium-containing halide perovskite CH3NH3PbI3. Very recently, the phase transitions and dynamic disorder of this structure, which has been extensively studied since the eighties, have come under renewed scrutiny, since they appear to be related to key PV performance parameters. Here, we propose to study for the first time the Bragg and diffuse scattering from a fully deuterated crystal, using time-sorted Laue diffraction on SXD. In addition to studying the average symmetry and the ion conduction pathways, this experiment, in combination with other techniques (see related OSIRIS proposal) will shed light on the dynamical molecular reorientation correlations in the different phases.
