摘要

Abstract

Formamidinium lead iodide (FAPbI

) is a newly developed hybrid perovskite that potentially can be used in high-efficiency solution-processed solar cells. Here

the temperature-dependent dynamic optical properties of thr

ee types of FAPbI

perovskite films (fabricated using three different precursor systems) are comparatively studied. The time-resolved photoluminescence (PL) spectra reveal that FAPbI

films made from the new precursor (a mixture of formamidinium iodide and hydrogen lead triiodide) exhibit the longest lifetime of 439 ns at room temperature

suggesting a lower number of defects and lower non-radiative recombination losses compared with FAPbI

obtained from the other two precursors. From the temperature-dependent PL spectra

a phase transition in the films is clearly observed. Meanwhile

exciton-binding energies of 8.1 and 18 meV for the high- and low-temperature phases are extracted

respectively. Importantly

the PL spectra for all of the samples show a single peak at room temperature

whereas at liquid-helium temperature the emission features two peaks: one in higher energy displaying a fast decay (0.5 ns) and a second red-shifted peak with a decay of up to several microseconds. These two emissions

separated by ~18 meV

are attributed to free excitons and bound excitons with singlet and triplet characters

respectively.
