From: Interplay between Exciton and Free Carriers in Organolead Perovskite Films
The simulation of density-dependent photoproducts inside perovskite films. (a) The relative ratio, x, of free carriers in total excitation density, according to Saha-Langmuir equation. (b) The simulated density of free carriers and excitons. (c) The simulated density-resolved PL 0 when the free carriers and exciton dynamically co-exist inside perovskite, and (d) when ECC become dominant in the system.
