Over the past decade, organic solar cells (OSCs) have achieved a dramatic boost in their power conversion efficiencies from about 6 % to over 16 %. In addition to developments in device engineering, innovative photovoltaic materials, especially fluorinated donors and acceptors, have become the dominant factor for improved device performance. This minireview highlights fluorinated photovoltaic materials that enable efficient OSCs. Impressive OSCs have been obtained by developing some important molds of fluorinated donor and acceptor systems. The molecular design strategy and the matching principle of fluorinated donors and acceptors in OSCs are discussed. Finally, a concise summary and outlook are presented for advances in fluorinated materials to realize the practical application of OSCs.
在过去的十年中，有机太阳能电池 (OSCs) 的功率转换效率已从约 6%大幅提高到 16%以上。除了在器件工程方面的发展外，创新性光伏材料，尤其是氟化给体和受体，已成为提高器件性能的主要因素。本综述重点介绍了实现高效 OSCs 的氟化光伏材料。通过开发一些重要的氟化给体和受体体系的模型，获得了令人印象深刻的 OSCs。讨论了 OSCs 中氟化给体和受体的分子设计策略和匹配原理。最后，对氟化材料在实现 OSCs 实际应用方面的进展进行了简要总结和展望。
