Hybrid perovskite materials have emerged over the past five years as absorber layers for new high-efficiency yet low-cost solar cells (PSCs) that combine the advantages of organic and inorganic semiconductors.
In order to lead to a better understanding of the electrical transport properties of PSCs, a comparison will be presented between the linear response (DFPT) approach of Density Functional Theory (DFT) and spectroscopic ellipsometry measurements on the hybrid CH3NH3PbI3 perovskite material
