摘　　要：钙钛矿太阳能电池(PSCs)因具有效率高、可溶液加工和成本低等优点受到了人们的广泛关注。然而,在PSCs的各个功能层及界面之间存在缺陷非辐射复合、界面接触不良和薄膜质量较差等问题,阻碍了PSCs光电转换效率和稳定性的提高。相较于石墨烯,同时含有sp^(1)与sp^(2)杂化碳原子的石墨炔具有独特的三角形孔、天然的带隙、超高的载流子迁移率以及优异的光电和机械性能,成为光电能源领域重要的候选材料。该文综述了石墨炔及其衍生物在PSCs的电子传输层、空穴传输层以及光吸收层中的应用,重点探讨了石墨炔及其衍生物在钝化缺陷、改善薄膜形貌和界面接触、提高载流子传输等方面的作用。最后,对石墨炔及其衍生物在PSCs领域中的发展提出了展望。Perovskite solar cells(PSCs)have attracted extensive attention due to their high efficiency,excellent solution processability and low manufacturing cost.However,problems like non-radiation recombination,poor interface contact and inferior film quality existing in various functional layers and interfaces of PSCs hinder the improvement of their photoelectric conversion efficiency and stability.Compared with graphene,graphdiyne possessing both sp^(1)-and sp^(2)-hybridized carbons is featured with unique triangular pores,natural band gap,ultra-high carrier mobility and excellent photoelectric and mechanical properties,which makes it an important candidate as photoelectric materials for use in the photovoltaic devices.In this review,the application of graphdiyne and its derivatives in the layers of electron transport,hole transport and light absorption in PSCs were discussed,especially their influence in defect passivation,film morphology and interface contact improvement,and carrier transport enhancement.Finally,the future outlook on graphdiyne and its derivatives in the field of PSCs was presented.
