Optical seminar | 23 October 2020

My talk will be devoted to the problem of phase instability (segregation) in mixed-halide perovskites. I will explain what is the segregation effect and why it happens. Moreover, I will present the findings of the study referred to photoinduced segregation in organic-inorganic and inorganic perovskites. Finally, the new method for suppression field-induced segregation in sky-blue light-emitting electrochemical cells will be presented.
