Optical and electronic properties. The photon conversion efficiency of hybrid perovskite based solar cells has increased from 6.9% to 23.6% within the last few years. The aim of this thesis is to investigate the optical and electronic properties of perovskite materials using magneto-optical techniques. We have investigated the relationship between the excitonic properties and the microstructure of hybrid perovskites. We have performed magneto-transmission measurement on MAPbI3 polycrystalline thin films and magneto-reflectivity measurement on a MAPbI3 single crystal. We find that, at low temperature, the exciton binding energy and reduced mass are the same for all MAPbI3 samples with a variety of crystal grain sizes.We have also investigate...
