Impact of Interfaces and Laser Repetition Rate on Photocarrier Dynamics in Lead Halide Perovskites.

Abstract

We studied charge carrier recombination in methylammonium lead iodide (MAPbI3) perovskite and the impact of interfaces on the charge carrier lifetime using time-resolved photoluminescence. Pristine films and those covered with organic electron and hole transport materials (ETM and HTM) were investigated at various laser repetition rates ranging from 10 kHz… (More)
