摘　　要：有机太阳能电池(OSCs)对实现低碳经济的发展具有重要意义。因其具有质轻、制备柔性、便携式设备等独特优势,具有巨大的商业开发价值。全聚合物太阳能电池(All-PSCs)凭借良好的光热稳定性及机械性能,被认为更有潜力应用于未来的柔性、可穿戴设备中。然而,目前的能量转换效率(PCE)相比基于小分子受体材料的光伏器件还相对较低,其中一个最重要的原因是缺乏高效的聚合物受体。本文首先将对发展节点以及目前应用高效率All-PSCs中的受体聚合物的研究进展进行简要介绍,随后将重点对其中通过无规共聚策略合成的聚小分子受体聚合物的优势与发展进行综述并对未来聚小分子受体聚合物的发展进行展望。Organic solar cells(OSCs)are of great significance for the development of a low-carbon economy.Because of its unique advantages such as light weight,flexible preparation and portable equipment,it has great commercial development value.All-polymer solar cells(All-PSCs)are considered to have more potential to be used in flexible and wearable devices in the future due to their good photothermal stability and mechanical properties,however,the current PCE is still relatively low compared to photovoltaic devices based on small molecule receptor materials,and one of the most important reasons is the lack of efficient polymer acceptors.The development nodes and the research progress on acceptor polymers in high-efficiency All-PSCs were briefly introduced,and then focused on the advantages and development of poly small molecule acceptor polymers synthesized by random copolymerization strategy,the future development of poly small molecule receptor polymers was prospected.
