Hybrid perovskites have emerged as promising candidates for highly efficient optoelectronic devices, including solar cells, light-emitting diodes, photodetectors, and lasers. However, the limited stability of hybrid perovskite materials and the corresponding devices remains an ongoing scientific challenge. One of the underlying reasons for this relates to the mixed ionic-electronic conductivity, which leads to the migration of mobile ions under device operation conditions that can be detrimental for the performance. These instabilities have stimulated the development of a number of promising strategies to address them, such as employing passivation agents, as well as using low-dimensional perovskites. While these unique properties of hybrid perovskite materials increase the level of complexity in understanding their optoelectronics, they have also paved the way to innovative applications, such as in resistive switching memory elements and battery materials.
The aim of this symposium is to bring together experts from various disciplines and provide a unique forum for discussion towards deepening the understanding of the relationship between hybrid perovskite dimensionality and mixed ionic-electronic conductivity with relevance for stability and performance of perovskite-based devices.
For your information, extended versions of contributions presented during this symposium can be published in a special collection, featured in Frontiers in Energy Research.

Dr. Moritz H. Futscher obtained his PhD in physics from the University of Amsterdam in January 2020 for his work performed at the research institute AMOLF. His PhD thesis focused on degradation channels related to ion migration and performance limitations of metal halide perovskites. After completing his PhD, he joined the Swiss Federal Laboratories for Materials Science and Technology (Empa) as a postdoctoral researcher and Rubicon Fellow working on metal halide perovskites and thin-film solid-state batteries. His main interest lies in understanding and harnessing the mixed ionic-electronic conductivities of different materials for novel applications related to renewable energy conversion and storage.
