From: Characterization of Bi-doped FAPbI3 perovskite films investigated by X-ray absorption spectroscopy
(a) XRD patterns of films under all conditions compared with ITO glass and the calculated XRD spectrum of the cubic FAPbI3 structure. (b) Inset is enlarged 2\(\theta\) range, from 13° to 15° of XRD patterns of perovskite films.
