Detection and characterization of defect states in organometallic halide perovskites

Popis výsledku v původním jazyce

In this work we present a comparison of an absorption spectra of MAPbBr3 single crystal obtained by FTPS, PL and PDS. This comparison shows a significant difference in the absorption spectra obtained using different methods and experimental conditions such as applied voltage in FTPS or different detection and excitation spot in PL measurements. Using this approach, we were able to observe defect states with energy level E = 2.18 ± 0.02 eV. Comparing FTPS measurements with two different arrangements of contacts we were able to identify these defect states as bulk defect.
