Abstract
Provided are a dipolar molecule-stabalized perovskite material and an optoelectronic device. The invention aims to provide the perovskite material with the stable dipolar molecules and the optoelectronic device, which can indirectly enhance an interaction between metal cations and halogen anions, reduce a defect state density in the perovskite material, and inhibit ion migration in the perovskite material by utilizing dipolar groups in a dipolar molecule stabilizer. A component of the perovskite material with the stable dipolar molecules is D: A' 2An-1BnX3n+1 or D: ABX3, wherein A′ is an organic amine cation, A is a monovalent cation, B is a metal cation, X is a monovalent anion, and D is the dipolar molecule stabilizer. A thermal stability, a phase stability and a photoluminescence stability of the material are remarkably enhanced, and working stabilities and efficiencies of the perovskite material and the optoelectronic device are remarkably improved.
