With outstanding photovoltaic properties, metal halide perovskite materials have marked great achievements in the field of next-generation solar cells; however, there still remain some challenges that hinder the commercialization progress regarding device efficiency and stability. Introducing novel materials with enhanced properties in perovskite solar cells (PSCs) is a promising strategy to overcome these difficulties. Two-dimensional materials (e.g., graphene and its derivatives, transition-metal dichalcogenides, and black phosphorus) have been widely investigated and applied in electronics and optoelectronics owing to their preeminent properties with the unique van der Waals structure. Herein recent advancements in the incorporation of 2D materials into PSCs are summarized. Three key points including optimizing perovskite crystallization, promoting charge transport, and passivating of defects for the enhanced efficiency and stability of PSCs by 2D materials are discussed. In the end, some perspectives on tackling the challenges for the PSCs and the 2D material coordination for higher device efficiency and stability are outlined.

用于提高效率和稳定性的钙钛矿太阳能电池二维材料

金属卤化物钙钛矿材料凭借出色的光伏性能，在下一代太阳能电池领域取得了巨大成就；然而，在器件效率和稳定性方面仍然存在一些阻碍商业化进程的挑战。在钙钛矿太阳能电池 (PSC) 中引入具有增强性能的新型材料是克服这些困难的有前途的策略。二维材料（如石墨烯及其衍生物、过渡金属二硫属化物和黑磷）由于其独特的范德华结构而具有卓越的性能，因此在电子和光电子领域得到了广泛的研究和应用。本文总结了将 2D 材料纳入 PSC 的最新进展。三个关键点包括优化钙钛矿结晶，讨论了促进电荷传输和钝化缺陷以提高二维材料 PSC 的效率和稳定性。最后，概述了解决 PSC 和 2D 材料协调挑战以提高设备效率和稳定性的一些观点。
