Metal halide perovskites have emerged as versatile semiconductors with exceptional optoelectronic properties, driving advances across photovoltaics, light-emitting devices, photodetectors, and photoelectrochemical systems. However, their intrinsic and extrinsic instability remains a significant bottleneck toward large-scale deployment. Degradation under moisture, heat, light, oxygen, and bias, limits device performance and lifetime. These challenges affect both lead- and tin -based perovskites, and are critical across different device formats, small area cells and more abrupt in large-area modules.
The symposium will address the latest developments in understanding and improving the stability of perovskite materials and devices. Topics will include intrinsic material stability via compositional and structural engineering, encapsulation strategies, interface passivation, additive engineering, and innovative device architectures (e.g., HTL/ETL-free, tandem, or flexible formats).
Emphasis will also be placed on stability in photovoltaic applications, and others such as photoelectrochemical water splitting, radiation detection, and light emission. Contributions covering scalable fabrication methods, accelerated aging protocols, and reliability under operational conditions are encouraged. We welcome discussions encompassing both experimental and theoretical approaches, aiming to define robust pathways toward durable, high-performance perovskite-based technologies.

Rafael AbarguesDr Stefania Cacovich is currently a CNRS researcher working at IPVF. Her research activity lies in the field of the advanced characterization of hybrid and inorganic materials for photovoltaic applications by employing a multi-scale and multi-technique approach.
Her research into hybrid devices started during her doctoral studies (2014-2018), carried out at the Department of Materials Science of the University of Cambridge (UK) under the supervision of Prof Caterina Ducati. Her thesis focused on the study of the chemical, structural and morphological properties of hybrid organic-inorganic thin films and photovoltaic devices using advanced analytical electron microscopy techniques. In 2018, she moved to Paris for a postdoctoral research position at IPVF to work on multidimensional spectrally and time resolved photoluminescence imaging methods. From 2020-2022, she was Marie Curie Individual Post-doctoral fellow in Physics at CNRS (UMR 9006) with a project aimed at exploring the fundamental photophysical processes underlying the operation of advanced optoelectronic devices.
Joseph M. Luther obtained B.S. degrees in Electrical and Computer Engineering from North Carolina State University in 2001. At NCSU he began his research career under the direction of Salah Bedair, who was the first to fabricate a tandem junction solar cell. Luther worked on growth and characterization high-efficiency III-V materials including GaN and GaAsN. His interest in photovoltaics sent him to the National Renewable Energy Laboratory (NREL) to pursue graduate work. He obtained a Masters of Science in Electrical Engineering from the University of Colorado while researching effects of defects in bulk semiconductors in NREL�s Measurements and Characterization Division. In 2005, He joined Art Nozik�s group at NREL and studied semiconductor nanocrystals for multiple exciton generation for which he was awarded a Ph.D. in Physics from Colorado School of Mines. As a postdoctoral fellow, he studied fundamental synthesis and novel properties of nanomaterials under the direction Paul Alivisatos at the University of California and Lawrence Berkeley National Laboratory. In 2009, he rejoined NREL as a senior research scientist. His research interests lie in the growth, electronic coupling and optical properties of colloidal nanocrystals and quantum dots.
Loreta Angela Muscarella was born in Palermo, Italy. In 2012, she moved to Rome where she started a bachelor in chemistry at Sapienza - University of Rome. During her Master’s studies, she spent seven months at the University of Amsterdam (UvA) under the supervision of Dr. René Williams to write her thesis on the effect of metallic ions in mixed-halide perovskites to improve the stability and optoelectronic properties. She received her MSc degree in inorganic and physical chemistry cum laude (with honors). In 2018, Loreta joined the group of Prof. Dr. Bruno Ehrler at AMOLF as a PhD student. Here, she investigated the relation between structure and optoelectronic properties of 3D and layered 2D lead-halide perovskites by monitoring the optoelectronic properties of mechanically compressed perovskites. In 2022, she joined the group of Dr. Eline Hutter (Utrecht University) as a postdoc to study photochemistry processes using lead-free perovskites. Since January 2024, she is assistant professor at the Vrije Universiteit Amsterdam where her group will combine spectroscopy and compositional engineering of perovskite-based materials to investigate on the external stimuli response of the emerging perovskite-based materials.
