Abstract

Defect states in perovskites dictate the charge carriers behaviour, thus the ultimate optical and electrical properties. Here, the authors in-situ investigate trapped carrier dynamics in MAPbI3 thin films with ultra-fast temporal and high energetic resolution by means of ultrafast photocurrent spectroscopy.
