Abstract Naphthalenediimide (NDI) polymers are an important class of electron-accepting (acceptor or n-type) semiconductors for organic photovoltaic (OPV) or organic solar cell (OSC) applications. Blending them with compatible electron-donating (donor or p-type) polymers yields an OPV device known as bulk-heterojunction (BHJ) all-polymer solar cells (all-PSCs). Compared to the more extensively studied OPVs using fullerene derivatives as the acceptor material, all-PSCs provide important benefits such as chemical tunability, mechanical flexibility and ambient/stress stability. Through an extensive research on materials design and device optimization in the last five years, all-PSCs employing NDI-based polymers have achieved remarkable improvement in device power conversion efficiency (PCE), now surpassing 10% – a number that approaches the state-of-the-art organic photovoltaic (OPV) cells using fullerenes. In this review, recent development of NDI-based conjugated polymers used in all-PSCs will be highlighted.

用于全聚合物光伏的萘二亚胺 (NDI) 聚合物

摘要 萘二亚胺 (NDI) 聚合物是一类重要的电子接受(受体或 n 型)半导体,用于有机光伏 (OPV) 或有机太阳能电池 (OSC) 应用。将它们与相容的给电子(供体或 p 型)聚合物混合产生一种称为体异质结 (BHJ) 全聚合物太阳能电池 (all-PSC) 的 OPV 器件。与使用富勒烯衍生物作为受体材料的更广泛研究的 OPV 相比,全 PSC 提供了重要的好处,例如化学可调性、机械灵活性和环境/应力稳定性。通过过去五年对材料设计和器件优化的广泛研究,采用 NDI 基聚合物的全 PSC 在器件功率转换效率 (PCE) 方面取得了显着提高,现在超过 10%——这个数字接近使用富勒烯的最先进的有机光伏 (OPV) 电池。在这篇综述中,将重点介绍用于全 PSC 的基于 NDI 的共轭聚合物的最新发展。
