Imaging of Recombination Rates and Lifetime in Perovskite Thin Film Processing.

ABSTRACT: Large-scale fabrication and optimization of high-quality polycrystalline perovskite thin films present significant challenges in scientific research and industry. Shifting from single-spot measurements to imaging techniques facilitates the transition from laboratory-scale to large-scale processing. While single-spot photoluminescence (PL) methods provide high-depth insights into local optoelectronic characteristics, they are insufficient for assessing reliable information on homogeneity and spatial characteristics. Currently, no PL-based imaging method delivers a comparable level of information depth on charge carrier dynamics to single-spot PL methods. In response, this work introduces a non-invasive imaging technique based on double-pulse excitation. Varying the time delay between the pu
