EBSD analysis of Lead Halide Perovskites using Symmetry

Methylammonium Lead Halides (MALHs) are organic crystal compounds used in solar cells, LEDs, LASERs and photodetectors. The performance of these MALHs is heavily dependent on their grain size and texture, however, characterisation has previously been difficult using SEM-based techniques due to them being too sensitive to analyse with an electron beam.

Recent improvements to electron backscatter diffraction (EBSD) detectors now allow characterisation of grain size and texture in methylammonium lead iodide. For the first time, grain size and texture in MAPbI₃ has been characterised using EBSD and the Symmetry® detector.
