传统的三维（3D）卤化物钙钛矿（HP）由于其高的功率转换效率（PCE）而经历了快速发展。然而，3D钙钛矿在湿度和紫外线照射下的不稳定性阻碍了其商业化。在过去的几年里，二维（2D）卤化物钙钛矿引起了人们的关注，因为它们表现出更好的稳定性，由于在2D钙钛矿晶格中的脂肪族碳链的耐水性。在这篇综述中，我们根据应用对2D/3D钙钛矿进行分类[即，太阳能电池（SC）、发光二极管（LED）和光电探测器（PD）]。我们进一步讨论了最近的努力，在性能增强的2D/3D钙钛矿为基础的设备。然而，在2D/3D HP完全商业化之前仍然存在一些困难。文章将提出一些科技挑战和展望，为今后的发展指明方向。
The traditional three-dimensional (3D) halide perovskites (HPs) have experienced rapid development due to their highly power conversion efficiency (PCE). However, the instability of 3D perovskite on humidity and UV irradiation blocks their commercialization. In the past few years, two-dimensional (2D) halide perovskites attract much attention because they behave better stability due to the water resistance of the aliphatic carbon chains in the 2D perovskite lattice. In this review, we categorize the 2D/3D perovskites based on the applications [i.e., solar cells (SCs), light-emitting diodes (LEDs) and photodetectors (PDs)]. We further discuss the recent efforts in the performance enhancement of the 2D/3D perovskite-based devices. However, there are still some difficulties before 2D/3D HPs is fully commercialized. We will provide some scientific and technical challenges and prospects in the article to point out the future direction.
