Zernike webinar, prof. Artem Bakulin: Electron-phonon effects in hybrid perovskite electronic materials
|When:||Fr 19-06-2020 15:30 - 16:30|
Over the past several years, organohalide perovskites have proven to be one of the most interesting and promising materials for next-generation solar cells. However, they possess unusual properties of soft structure and high dynamic disorder, which arise from the interplay between the organic and inorganic sublattices that make up the material. Overall, we still lack a comprehensive understanding of the dynamical behaviour of within organohalide perovskites. In this seminar, I will present several case studies that help to shed light on the electron phonon interactions and dynamics of the organic cations that make up the organic sublattice in these materials. I will also discuss how their dynamics are affected by their interplay with the inorganic sublattice, and finally, how this interplay may give rise to coupling between the organic and inorganic parts of the perovskite.
