Metal halide perovskites have emerged as one of the most exciting classes of semiconductors suitable for a range of optical and optoelectronic applications. The understanding of their photophysics is highly important not only from the fundamental point of view, but also as a path for the development of novel applications. In this symposium, we bring together experts from theory and experiment that focus on the investigation of the various photophysical phenomena in metal halide perovskites. These include the study of the excitonic structure of metal halide perovskites, the characterization and control over their ionic and electronic defects and their interaction with light. In addition, we aim to highlight novel photonic applications of metal halide perovskites beyond photovoltaics that rely on their rich photophysics. These include for example devices that utilize the chiroptical properties of chiral 2D perovskites or photonic memory devices

Ivan Scheblykin obtained Ph.D. in 1999 from Moscow Institute of Physics and Technology and Lebedev Physical Institute of Russian Academy of Sciences on exciton dynamics in J-aggregates. After a postdoctoral stay in the KU Leuven, Belgium, he moved to Sweden to start the single molecule spectroscopy group at the Division of Chemical Physics in Lund University where he became a full professor in 2014. His interests cover fundamental photophysics of organic and inorganic semiconductors and, in particular, energy transfer, charge migration and trapping. The general direction of his research is to comprehend fundamental physical and chemical processes beyond ensemble averaging in material science and chemical physics using techniques inspired by single molecule fluorescence spectroscopy and single particle imaging.

Paulina Plochocka, Directrice de recherché de 2e classe (DR2) in Laboratoire National des Champs Magnétiques Intenses (LNCMI), CNRS in Toulouse.
P. Plochocka obtained her PhD cum-laude in 2004 at the University of Warsaw working on the dynamics of many-body interactions between carriers in doped semi-magnetic quantum wells (QW). During her first post doc at Weizmann Institute of science, she started working on the electronic properties of a high mobility 2D electron gas in the fractional and integer quantum Hall Effect regime. She continued this topic during second post doc in LNCMI Grenoble, where she was holding individual Marie Curie scholarship. At the same time, she enlarged her interest of 2D materials towards graphene and other layered materials as TMDCs or black phosphorus. In 2012 she obtained permanent position in LNCMI Toulouse, where she created the Quantum Electronics group, which investigates the electronic and optical properties of emerging materials under extreme conditions of high magnetic field and low temperatures. Examples include semiconducting layer materials such as transition metal dichalcogenides, GaAs/AlAs core shell nanowires and organic inorganic hybrid perovskites.
