The lack of electron acceptors with suitable green solvent processing and excellent device performance is an important problem that hinders the development and commercialization of organic solar cells (OSCs). Here, an ortho-ortho perylene diimide (PDI) dimer (oo-2PDI) is developed and used as an acceptor for use in efficient green-solvent-processed (GSP) OSCs. By using chlorobenzene (CB), anisole, and o-xylene as the processing solvents, power conversion efficiencies (PCEs) of 5.04%, 5.03%, and 5.78% were achieved without the additive, respectively. In addition, the non-fullerene oo-2PDI-based GSPOSCs show superior photovoltaic performance to [6,6]-phenyl-C₆₁-butyric acid methyl ester (PCBM)-based GSPOSCs under identical conditions. Therefore, these results demonstrate the possibility of achieving efficient non-fullerene GSPOSCs.

缺少具有合适的绿色溶剂处理和优异的器件性能的电子受体是阻碍有机太阳能电池（OSC）的开发和商业化的重要问题。在此，开发了邻二甲苯基二酰亚胺（PDI）二聚体（oo -2PDI），并将其用作有效的绿色溶剂处理（GSP）OSC中使用的受体。通过使用氯苯（CB），苯甲醚和邻二甲苯作为加工溶剂，在没有添加剂的情况下，功率转换效率（PCE s）分别达到5.04％，5.03％和5.78％。此外，基于非富勒烯oo -2PDI的GSPOSC显示出优于[6,6]-苯基-C _61的光伏性能。-丁酸甲酯（PCBM）的GSPOSC在相同条件下。因此，这些结果证明了获得有效的非富勒烯GSPOSC的可能性。
