Perovskite solar cells (PSCs), one of the most promising photovoltaic technologies, have been widely studied due to their high power conversion efficiency (PCE), low cost, and solution processability. The architecture of PSCs determines that high PCE and stability are highly dependent on each layer and the related interface, where nonradiative recombination occurs. Conventional synthetic chemical materials as modifiers have disadvantages of being toxic and costly. Natural molecules with advantages of low cost, biocompatibility, and being eco-friendly, and have improved PCE and stability by modifying both functional layers and interface. In this review, we discuss the roles of natural molecules on PSCs devices in terms of the perovskite active layer, interface, carrier transport layers (CTLs), and substrate. Finally, the summary and outlook for the future development of natural molecule-modified PSCs are also addressed.
钙钛矿太阳能电池（PSCs）是最具前景的光伏技术之一，因其高功率转换效率（PCE）、低成本和可溶液加工性而受到广泛研究。PSCs的结构决定了高PCE和稳定性高度依赖于每一层以及相关界面，非辐射复合在这些界面发生。传统的合成化学材料作为改性剂存在毒性大、成本高的缺点。天然分子具有低成本、生物相容性好和环保的优点，通过对功能层和界面进行改性提高了PCE和稳定性。在本综述中，我们从钙钛矿活性层、界面、载流子传输层（CTLs）和基底方面讨论了天然分子在PSCs器件中的作用。最后，还阐述了天然分子改性PSCs未来发展的总结与展望。
