Self-Trapped Excitons in Metal-Halide Perovskites Investigated by Time-Dependent Density Functional Theory

Yu Jin, Mariami Rusishvili, Marco Govoni +1

We present a theoretical study of the formation of self-trapped excitons (STEs) and the associated broadband emission in metal-halide perovskites Cs${}_4$SnBr${}_6$ and Cs${}_2$AgInCl$_6…
