随着对金属卤化物钙钛矿的不断研究，几何约束技术被广泛应用于降低材料维度和制备预先设计的结构，从而可以调节光学反射、散射和吸收，从而优化基于钙钛矿的光电器件的性能，提高其商业竞争力。钙钛矿活性层的形貌对光电性能和器件性能起着至关重要的作用。本文系统地总结了近年来各种钙钛矿结构的制备和制备方法，以及它们在光电探测器、太阳能电池、激光器和发光二极管等光电领域的应用进展。此外，还讨论了为下一代高质量光电器件制备独特的几何限定的钙钛矿形貌的剩余挑战和进一步改进。
With the continuous study of metal halide perovskite, geometry-confined technologies have been widely applied to reduce the material dimensionality and to produce pre-designed structures, which can tune optical reflectance, scattering, and absorption, thereby optimizing the performance of perovskite-based optoelectronic devices and improving their commercial competitiveness. The morphologies of perovskite active layer play a pivotal role in optoelectronic properties and the resulting device performances. In this review, we systematically summarized recent progress in the preparation and manufacture of various perovskite geometry-confined morphologies, as well as their promising advances in different optoelectronic applications, including photodetectors, solar cells (SCs), lasers, and light-emitting diodes (LEDs). In addition, the remaining challenges and further improvements of preparation unique geometry-confined perovskite morphologies for next-generation high quality optoelectronic devices are discussed.
