制备方法与用途

甲胺溴基钙钛矿为橙色固体,可用作钙钛矿材料。

甲胺溴基钙钛矿材料

甲胺溴基钙钛矿(MAPbBr3)的优势体现在:

高吸收系数:MAPbBr3可以吸收到更多的太阳光谱范围内的光子,具有更高的光电转换效率。

光稳定性更好:MAPbBr3的卤素离子配位基团不易和空气中的氧气和水分发生反应,因此其光稳定性更好,不容易让材料发生退化或降解。

更高的热稳定性:MAPbBr3的禁带宽度小,具有更高的载流子迁移率和更高的热稳定性,能够保持更高的光电转换效率,即在更高的温度条件下也能够工作。

更佳的外量子效率:相比 FAPbBr3,MAPbBr3 在更大势能范围内可以实现最大的外量子效率,也就是提高了光电转换效率。

甲胺溴基钙钛矿具有优异的光电性质:光吸收系数高、载流子迁移率大、载流子寿命长和散射长度大等,在太阳能电池、发光二极管、光电探测器和激光发射器等光电领域有着巨大的应用前景。

  • Systematic Studies on Chain Lengths, Halide Species, and Well Thicknesses for Lead Halide Layered Perovskite Thin Films
    作者:Yuko Takeoka、Keisuke Asai、Masahiro Rikukawa、Kohei Sanui

    Two-dimensional layered perovskite compounds, (CnH2n+1NH3)2(CH3NH3)m−1PbmX3m+1 (n = 2, 3, 4, 6, and 10; X = Cl, Br, and I; m = 1, 2, and 3) were systematically prepared. The influences of the barrier-size, halide species, and well thickness of the perovskite thin films on the quantum confinement structures were investigated. The layered perovskite films showed a strong and clear absorption peak due to excitons confined in inorganic quantum-wells. The exciton peak shifted to lower energy as the halide species was changed from Cl to Br and I. Furthermore, fine multilayer perovskite compound films were prepared by varying the spin-coating conditions.

The effect of different size (micro-cube & nano-particles) of perovskite material on structural, optical, thermal stability and degradation kinetics has been examined.

  • Structural Phase Transition and Electrical Conductivity of the Perovskite CH<sub>3</sub>NH<sub>3</sub>Sn<sub>1</sub>-<i><sub>x</sub></i>Pb<i><sub>x</sub></i>Br<sub>3</sub>and CsSnBr<sub>3</sub>

    A series of solid solutions, CH3NH3Sn1−xPbxBr3 (x=0–1), having cubic perovskite structures was obtained by solid-state reactions. The 119Sn Mössbauer spectra for x<0.4, however, indicated that the tin environment was considerably distorted from a regular octahedron at 110 K. On the other hand, a single Lorentzian spectrum having a large isomer shift was observed for x>0.7, suggesting the presence of a regular SnBr6 octahedra in the perovskite CH3NH3PbBr3 matrix. The high electrical conductivity of the perovskite CsSnBr3 drastically decreased upon the replacement of the cation by CH3NH3 and the central metal by Pb. This behavior suggests that both the infinite linear chain (–Br–Sn(Pb)–Br–) and its bond length have significant importance regarding electrical conductivity.
    通过固态反应获得了一系列具有立方包晶结构的固溶体 CH3NH3Sn1-xPbxBr3(x=0-1)。然而,x<0.4 时的 119Sn 莫斯鲍尔光谱表明,在 110 K 时,锡的环境与规则的八面体相比发生了很大的扭曲。另一方面,x>0.7 时观察到了具有较大同分异构体偏移的单洛伦兹光谱,表明在包晶 CH3NH3PbBr3 基体中存在规则的 SnBr6 八面体。当阳离子被 CH3NH3 取代,中心属被 Pb 取代时,包晶 CsSnBr3 的高导电率急剧下降。这种行为表明,无限线性链(-Br-Sn(Pb)-Br-)及其键长对导电性具有重要意义。

    330.4 K (9.7 J K −1 mol −1 ). The transition entropies indicated that the phase transitions are of the order-disorder type. They are interpreted with three possible models involving the methylammonium ions disordered with respect to the orientation of the C-N axis itself and around the C-N axis. The infrared line width of the v 12 vibration of the methylammonium ion depended markedly on the temperature
