Title:
PEROVSKITE COMPOSITE COMPRISING ANTIMONY TRIFLUORIDE, ELECTRONIC ELEMENT COMPRISING SAME, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/149636
Kind Code:
A1
Abstract:
A perovskite composite comprising antimony trifluoride, an electronic element comprising same, and a preparation method therefor are disclosed. The perovskite composite comprises tin (Sn)-based perovskite and antimony trifluoride (SbF3) so that lead (Pb) is not added thereto, and has high hole concentration (≤ 1014 cm-1), and thus can be used for an optoelectronic device.
