Seminar Highlights Innovations in Perovskite Research

A collaborative seminar took place on Tuesday, August 19, 2025, featuring Professor Bruno Ehrler from AMOLF in The Netherlands, who presented an illuminating talk on “A Simple Question, Many Answers: How Mobile are the Atoms in a Perovskite Solar Cell?”

The hybrid seminar, held onsite and online, provided an excellent opportunity to delve into the intricacies of metal halide perovskite solar cells and the impact of mobile ions on their performance. The discussion included colleagues from the University of Turku and Åbo Academy, as well as the University of Tampere, across the Departments of Chemistry, Physics, and Materials Engineering. Professor Ehrler shed light on the limitations of current measurement techniques and advocated for a combined approach that integrates multiple electrical measurements with drift-diffusion simulations. He further discussed the implications of these strategies on novel neuromorphic computing devices.

Professor Ehrler recently completed a three-day visit at the University of Turku. He is a long-term collaborator engaged with our projects on “Smart Hybrid Materials for Opto(electro)ionics,” funded by the European Research Council, and “Supramolecular Engineering of Layered Double Perovskites for Renewable Energy Conversion in Photovoltaics,” funded by the Research Council of Finland. The visit has stimulated further collaborative initiatives that will continue over the upcoming years.
