Ion Migration in Halide Perovskites

This 15-minute seminar from the Lennard-Jones Centre discussion group features Prof. Bo Cai from the Nanjing University of Posts and Telecommunications in China discussing ion migration in halide perovskites. Explore the critical challenges facing these promising semiconductors for next-generation photovoltaic devices, particularly their instability when exposed to illumination and electric fields. Learn about the intricate connection between electronic density of states and barriers to ion migration energy, which is key to addressing instability issues and advancing the commercial development of halide perovskites. The seminar was recorded on November 13th, 2023, and is presented by Cambridge Materials.
