卤化物钙钛矿，特别是有机金属卤化物钙钛矿，由于其优异的光学性能、低廉的生产成本和简单的制备工艺，已成为人们研究的热点。高吸收系数，加上直接带隙和各种可获得的沉积方法，使这些钙钛矿成为一种优秀的材料类别，可用于从太阳能电池到发光二极管的大量应用，以及从简单的薄膜固态太阳能电池到高度有序的纳米结构太阳能电池和传感器的各种长度尺度的图像传感器。钙钛矿的缺点是，由于不佳的封装性，当受到环境条件的影响时，它们的稳定性较差，这可以通过使用纳米结构作为额外的封装物来解决。本文概述了制备纳米钙钛矿型捕光器件的不同方法，讨论了纳米结构对复合钙钛矿型捕光器件性能和稳定性的影响，并展望了未来的研究方向。
Halide perovskites in general and organometal‐halide perovskites in particular have become an intensely researched topic due their excellent optical properties, cheap production costs, and easy fabrication procedures. A high absorption coefficient, paired with a direct bandgap and a wide variety of accessible deposition method, makes these perovskites an excellent materials class for use in a plethora of applications, ranging from solar cells to light‐emitting diodes, and image sensors with architectures of varying length scales ranging from simple thin‐film solid‐state solar cells to highly ordered nanostructured solar cells and sensors. A downside of perovskites is their poor stability when subjected to ambient conditions as a consequence of poor encapsulation which, can be countered by using a nanostructured as additional encapsulation. In this work, different approaches to fabricate nanostructured perovskite‐based light harvesting devices are outlined and the influences of nanostructuring on the performance and stability of the incorporated perovskites are discussed, as well as future research perspectives being highlighted.
