Understanding ionic movement in metal halide perovskites is central to improve the stability and performance of the devices and broaden their applicability beyond optoelectronic and electrochemical devices. This symposium will bring together researchers investigating ion migration mechanisms, defect chemistry, lattice dynamics, and coupled ionic–electronic processes across hybrid, inorganic, and low-dimensional perovskite systems. The objective is to provide a platform for discussing cutting-edge experimental and computational approaches—ranging from operando characterization and advanced spectroscopy to atomistic simulations and multiscale modeling—that reveal how ions move, interact, and influence material behavior. By highlighting both fundamental insights and device-relevant implications, the symposium aims to stimulate interdisciplinary discussions that connect ionic transport with long-term material stability, degradation pathways, switching phenomena, and functional device engineering. We invite contributions from materials scientists, chemists, physicists, and engineers working to unravel the complexities of ionic motion and harness it for next-generation technologies.

Silvia Colella is a researcher at the National research council, CNR-NANOTEC, in Bari, Italy. She received her PhD in “Nanoscience” at National Nanotechnology Laboratory in Lecce (Italy), in 2010. She has been visiting student in the group of professor Luisa De Cola at the Westfälische Wilhelms-Universität of Münster (Germany), where she dealt with the synthesis and photophysical characterization of electroluminescent metal complexes. In 2010 she joined BASF – The Chemical Company (Strasbourg) with a Marie Curie fellowship as experienced researcher in the frame of the EU project ITN SUPERIOR, working on Dye Sensitized Solar Cells. She continued as post-doc researcher at the Institut de science et ingénierie supramoléculaires (ISIS) in Strasbourg, France. In 2012 she started her independent research in Lecce (Italy) at the University of Salento in collaboration with CNR-NANOTEC, the team focused on the conception and optoelectronic characterization of innovative optoelectronic devices based on hybrid halide perovskites. Many high impact publication were produced in this time interval, among them one of the first report in halide perovskite for PV exploitation (Colella et al, Chemistry of Materials, 2013 25, 4613-4618).
Silvia Colella is author of >70 peer-reviewed publications in renowned international journals (including Energy and Environmental Science, Advanced Materials, ACS Energy Letters).
