Abstract

Nitrogen-functionalized graphene (N-FG) derivatives are versatile materials with broad chemical applicability and straightforward preparation methods. N-FG involves grafting nitrogen compounds onto graphene, categorized as ammonium hydroxide, amines, and quaternary ammonium salts. This review highlights N-FG synthesis via chemical, thermochemical, electrochemical, and electromagnetic methods. It emphasizes N-FG's role in photovoltaic (PV) technologies, particularly perovskite solar cells (PSCs) and dye-sensitized solar cells (DSSCs). In PSCs, N-FG excels as an interfacial layer, enhancing performance when in direct contact with perovskite films. In DSSCs, its applications include Pt-free cathodes, photoanodes, and electrolyte additives, achieving power conversion efficiencies of 8–8.5%. The review also explores N-FG's potential in other PV technologies, such as thin-film and silicon solar cells, while addressing challenges and opportunities for advancing its role in sustainable energy solutions.

氮功能化石墨烯增强光伏应用的研究进展
氮功能化石墨烯(N-FG)衍生物具有广泛的化学适用性和简单的制备方法。N-FG涉及将氮化合物接枝到石墨烯上,分类为氢氧化铵,胺和季铵盐。综述了N-FG的化学、热化学、电化学和电磁合成方法。它强调了N-FG在光伏(PV)技术中的作用,特别是钙钛矿太阳能电池(PSCs)和染料敏化太阳能电池(DSSCs)。在psc中,N-FG作为界面层表现优异,当与钙钛矿膜直接接触时,性能得到增强。在DSSCs中,它的应用包括无pt阴极、光阳极和电解质添加剂,实现了8-8.5%的功率转换效率。该报告还探讨了N-FG在其他光伏技术(如薄膜和硅太阳能电池)方面的潜力,同时解决了其在可持续能源解决方案中发挥作用的挑战和机遇。
