The advances in halide perovskite-based optoelectronic devices originate from their unconventional semiconductor properties, including defect tolerance, strong light-matter interaction, a dynamic lattice, and a highly tunable electronic structure. Fully exploiting the potential of perovskites, therefore, demands a deeper understanding of their fundamental properties, encompassing charge-carrier dynamics, defect physics, and structure–property relationships. Building on the success of PeroFun25, we propose PeroFun26 at MatSus 2026 as a platform to highlight recent advances in the fundamental understanding of perovskite materials, with particular emphasis on their behavior in device-relevant architectures. In multilayer device stacks, interfaces can significantly alter charge, ionic, and optical processes; consequently, interface effects and strategies to mitigate interface-induced performance losses will be a central focus of the symposium. The symposium will emphasize emerging studies that probe composition, structure, optoelectronic properties, and ionic/electronic transport, especially those providing high spatial and temporal resolution. These approaches are critical for elucidating operational mechanisms and degradation pathways, enabling the rational design of more efficient and durable devices. Contributions on emerging perovskite-based applications, including field-effect transistors, thermoelectrics, memristive and neuromorphic devices, lasing, single-photon emission, polarized emission, and spintronics, are also welcomed

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.

My research focuses on understanding charge transport and photophysical processes in emerging semiconductor systems, including organic semiconductors, perovskites, self-assembled nanostructures, and two-dimensional materials. Unlike conventional inorganic semiconductors, these materials exhibit complex transport behavior and disorder-driven phenomena that reveal new approaches for device functionality. We employ a wide range of electrical, spectroscopic, microscopic, and structural characterization techniques to probe these processes and identify key instabilities. Insights gained from these studies are leveraged to develop next-generation technologies, including high-efficiency photovoltaics, ultra-bright light-emitting devices, low-power flexible electronics, and advanced medical diagnostic platforms.
