The organic-inorganic hybrid perovskite solar cells with its great advances in the cost-efficient fabrication process and high-power conversion efficiency have outperformed a range of traditional photovoltaic technologies such as multi-crystal Si and CIGS. Meanwhile, the undesirable operational stability of perovskite solar cell lags its commercialization where perovskite solar cells suffer a lattice degradation and lost the capability of energy harvesting when encountering the crucial environmental factors such as high moisture and strong irradiation. Accordingly, improving the operational stability becomes one of the decisive factors to govern the next wave advancement of the perovskite solar cells. Among a plethora of reported strategies to improve the stability, building a multidimensional (2D/3D) heterojunction perovskite as the light-harvesting layer has recently become one of the most credible approaches to stabilize the PSCs without sacrificing of photovoltaic performance. In this mini-review, the recent progress in 2D/3D multidimensional PSCs has been elaborately reviewed. Detailed information including the long-chain cation materials, development of fabrication process, charge carrier dynamics, optoelectronic properties, and their impact on the photovoltaic performances has been systematically discussed. Finally, some of the further challenges are highlighted while outlining the perspectives of multidimensional 2D/3D perovskites for stable and high-performance PSCs.

有机-无机混合钙钛矿太阳能电池在低成本制造工艺和高功率转换效率方面取得了巨大进步，其性能已经超过了多种传统光伏技术，例如多晶Si和CIGS。同时，钙钛矿太阳能电池的不良操作稳定性落后于其商业化，其中钙钛矿太阳能电池在遇到诸如高湿度和强辐射等关键环境因素时遭受晶格退化并失去能量收集的能力。因此，提高操作稳定性成为控制钙钛矿太阳能电池的下一波发展的决定性因素之一。在许多已报告的提高稳定性的策略中，随着光收集层的发展，构建多维（2D / 3D）异质结钙钛矿已成为在不牺牲光伏性能的情况下稳定PSC的最可靠方法之一。在此小型审查中，对2D / 3D多维PSC的最新进展进行了详尽的审查。系统地讨论了包括长链阳离子材料，制造工艺的发展，电荷载流子动力学，光电特性及其对光伏性能的影响在内的详细信息。最后，在概述多维2D / 3D钙钛矿对稳定和高性能PSC的观点时，突出了一些其他挑战。在此小型审查中，对2D / 3D多维PSC的最新进展进行了详尽的审查。系统地讨论了包括长链阳离子材料，制造工艺的发展，电荷载流子动力学，光电特性及其对光伏性能的影响在内的详细信息。最后，在概述多维2D / 3D钙钛矿对稳定和高性能PSC的观点时，强调了一些其他挑战。在此小型审查中，对2D / 3D多维PSC的最新进展进行了详尽的审查。系统地讨论了包括长链阳离子材料，制造工艺的发展，电荷载流子动力学，光电特性及其对光伏性能的影响在内的详细信息。最后，在概述多维2D / 3D钙钛矿对稳定和高性能PSC的观点时，突出了一些其他挑战。
