Unravelling material properties of halide perovskites by combined microwave photoconductivity and time-resolved photoluminescence spectroscopy

Abstract

Simultaneous measurements of trPL and microwave photoconductivity facilitate a global fit of charge carrier density in perovskite materials. This enables the extraction of fundamental rate constants and the mobility ratio of electrons and holes.

Closing the loop: recycling of MAPbI3 perovskite solar cells

“…We implemented a bimolecular-trapping–detrapping model within a Bayesian optimization-based fitting algorithm to fit the TR-PL results. This model, as detailed in the work of Péan, 43 and our fitting procedure, consistent with the methodology described by Kupfer, 44 facilitate a robust analysis. The fitting extracts information on the recombination of excited charge carriers.…”
