Three-dimensional (3D) organic-inorganic lead halide perovskites have emerged in the past few years as a promising material for low-cost, high-efficiency optoelectronic devices. Spurred by this recent interest, several subclasses of halide perovskites such as two-dimensional (2D) halide perovskites have begun to play a significant role in advancing the fundamental understanding of the structural, chemical, and physical properties of halide perovskites, which are technologically relevant. While the chemistry of these 2D materials is similar to that of the 3D halide perovskites, their layered structure with a hybrid organic-inorganic interface induces new emergent properties that can significantly or sometimes subtly be important. Synergistic properties can be realized in systems that combine different materials exhibiting different dimensionalities by exploiting their intrinsic compatibility. In many cases, the weaknesses of each material can be alleviated in heteroarchitectures. For example, 3D-2D halide perovskites can demonstrate novel behavior that neither material would be capable of separately. This review describes how the structural differences between 3D halide perovskites and 2D halide perovskites give rise to their disparate materials properties, discusses strategies for realizing mixed-dimensional systems of various architectures through solution-processing techniques, and presents a comprehensive outlook for the use of 3D-2D systems in solar cells. Finally, we investigate applications of 3D-2D systems beyond photovoltaics and offer our perspective on mixed-dimensional perovskite systems as semiconductor materials with unrivaled tunability, efficiency, and technologically relevant durability.
在过去几年中，三维（3D）有机-无机铅卤化物钙钛矿已成为一种有前景的低成本、高效光电器件材料。受近期这种关注的推动，卤化物钙钛矿的几个子类，如二维（2D）卤化物钙钛矿，已开始在推进对卤化物钙钛矿的结构、化学和物理性质的基础理解方面发挥重要作用，这些性质在技术上具有相关性。虽然这些二维材料的化学性质与三维卤化物钙钛矿相似，但其具有有机-无机混合界面的层状结构会诱导出新的涌现性质，这些性质可能显著或有时微妙地具有重要意义。通过利用不同维度材料之间的内在兼容性，可以在结合不同维度材料的系统中实现协同性质。在许多情况下，每种材料的弱点在异质结构中可以得到缓解。例如，3D-2D卤化物钙钛矿可以表现出单独任何一种材料都无法实现的新颖行为。本综述描述了3D卤化物钙钛矿和2D卤化物钙钛矿之间的结构差异如何导致它们不同的材料性质，讨论了通过溶液处理技术实现各种结构的混合维度系统的策略，并对3D-2D系统在太阳能电池中的应用给出了全面展望。最后，我们研究了3D-2D系统在光伏领域之外的应用，并对混合维度钙钛矿系统作为具有无与伦比的可调性、效率和技术相关耐久性的半导体材料给出了我们的观点。
