Interfaces in perovskite devices represent critical bottlenecks that limit performance, stability, and scalability toward commercial deployment. This symposium addresses fundamental and applied challenges at perovskite heterojunctions, including non radiative recombination, ion migration, chemical degradation, optical losses and energetic misalignment at charge transport interfaces. We welcome contributions on innovative interfacial engineering strategies, such as molecular passivation, self assembled monolayers, buffer layers, and surface treatments, that are compatible with large-scale fabrication methods. Special emphasis will be placed on understanding how interface quality translates from laboratory-scale devices to industrial manufacturing processes, including blade coating, slot-die coating, and roll-to-roll production. The symposium spans both photovoltaic and optoelectronic applications (LEDs, photodetectors, X-ray sensors), fostering dialogue between fundamental interface science and practical solutions. Our objective is to identify scalable interfacial modifications that can bridge the gap between record efficiencies and commercially viable perovskite technologies.

Dr. Clara Aranda Alonso, received her doctorate degree in Science from University Jaume I in 2019 at the Institute of Advanced Materials (INAM) (Castellón, Spain). She worked as postdoctoral researcher at the Forschungszentrum Jülich and Institute for Photovoltaics (ipv) at the University of Stuttgart (Germany) for two years. Then she moved to the Institute of Materials Science (ICMUV) at the University of Valencia (Spain) as a Margarita Salas fellow. Currently, she is working at Universidad Pablo de Olavide in Seville (Spain). Her work is focused on the synthesis and characterization of wide band gap perovskite materials, both in thin film and single crystal configuration, for photoconversion devices such as solar cells, photodetectors and memristors, using impedance spectroscopy as the main characterization tool.
