Abstrakt: Cs 2 TiBr 6 stands as a promising Pb-free alternative perovskite material having demonstrated its potential in photovoltaics. However, it is considered to be highly unstable in air, hindering further improvements and raising concerns regarding its practical implementation. In this work, we report on a method to improve the stability of Cs 2 TiBr 6 NCs using SnBr 4 in a facile surface treatement.
