Document Type and Number:
WIPO Patent Application WO/2024/005498
Kind Code:
A1
Abstract:
The present invention provides a thin film comprising a perovskite halide represented by chemical formula 1. [Chemical Formula 1] AB(BrxCly)3, wherein, in chemical formula 1, A is a monovalent cation consisting of a combination of NH2CHNH2 + (formamidinium, FA), CH3NH3 + (methyl ammonium, MA), and Cs+, wherein FA is included in an amount of 0.2-0.8 moles with respect to 1 mole of the monovalent cation, B is at least one divalent cation selected from Pb2+, Sn2+, Ge2+, Ti2+, Zr2+, Mn2+, Ni2+, Fe2+, Zn2+, and Cu2+, and x and y satisfy 0.5≤x≤0.8, 0.2≤y≤0.5, and x+y=1.
