Abstract: Provided are a perovskite material with stable bipolar molecules and a photoelectric device. The invention aims to provide the perovskite material with the stable bipolar molecules and the photoelectric 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 bipolar groups in a bipolar molecule stabilizer. A component of the perovskite material with the stable bipolar 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 bipolar 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 photoelectric device are remarkably improved.

Abstract: An optoelectronic device includes a semiconductor substrate, wherein a first transport layer is formed on a first partial region of the semiconductor substrate; a first insulation layer is formed on a second partial region around the first partial region; the first transport layer is formed on the first insulation layer; an interface layer is formed on the first transport layer; a light-emitting material layer containing perovskite material is formed on the interface layer; a second insulation layer is formed on the light-emitting material layer in the second partial region and on the light-emitting material layer near a second partial region side in the first partial region, so that the characteristic size of a single light-emitting pixel or effective working region is adjustable.
