Physical properties of 2D multilayered perovskites and 2D/3D bilayers for photovoltaics

Résumé

The presentation will focus first on the physical properties of multilayered perovskites, including relativistic effects, deviations from 2D Rydberg series of the exciton and hot carrier effects [1-4]. Then, their application to solar cells, either in the Ruddlesden-popper structure [5] or in the Dion-Jacobson one [6], will be described. Finally, the interplay between structural, interfacial and optoelectronic properties of 2D multilayered halide perovskites, and their interfaces with 3D perovskites in stable bilayer solar cells with thick layers will be presented [7,8]. references: [1] J Even et al Electronic model for self-assembled hybrid organic/perovskite semiconductors: Reverse band edge electronic states ordering and spin-orbit coupling, Phys.
