Guo, Dengyang (author), Andaji Garmaroudi, Zahra (author), Abdi-Jalebi, Mojtaba (author), Stranks, Samuel D. (author), Savenije, T.J. (author)The highest reported efficiencies of metal halide perovskite (MHP) solar cells are all based on mixed perovskites, such as (FA,MA,Cs)Pb(I<sub>1-x</sub>Br<sub>x</sub>)<sub>3</sub>. Despite demonstrated structural changes induced by light soaking, it is unclear how the charge carrier dynamics are affected across this entire material family....journal article 2019

(author)Metal halide perovskites are generating enormous excitement for use in solar cells and light-emission applications, but devices still show substantial non-radiative losses. Here, we show that by combining light and atmospheric treatments, we can increase the internal luminescence quantum efficiencies of polycrystalline perovskite films from 1...journal article 2017
