The ternary strategy exhibits great potential in optimizing the photon harvesting and phase separation of active layers. In this work, non-fullerene MF1 was selected as the third component to prepare efficient ternary organic solar cells (OSCs) by finely optimizing the MF1 content in the acceptors. The optimized power conversion efficiency (PCE) of 15.31% is achieved in the ternary OSCs with 20 wt% MF1 content in the acceptors and 100 nm active layer thickness, also exhibiting a relatively high fill factor (FF) of 78.05%. The relatively high FF indicates efficient charge transport and collection in the optimized ternary OSCs, which should be beneficial to achieve efficient thick-film OSCs. It is highlighted that a PCE of 14.57% is achieved in the optimized ternary OSCs with 300 nm thick active layers compatible with the roll-to-roll (R2R) large-scale printing process. To date, high performance thick-film ternary non-fullerene OSCs have seldom been reported. This work indicates that the thick-film ternary strategy has great potential in achieving efficient large-scale OSCs.

具有300 nm厚有源层的三元有机太阳能电池的效率超过14.5％，填充因子达到71.6％

三元策略在优化有源层的光子收集和相分离方面显示出巨大的潜力。在这项工作中，非富勒烯MF1被选为第三种成分，通过精细优化受体中的MF1含量来制备高效的三元有机太阳能电池（OSC）。在三元OSC中，在受体中MF1含量为20 wt％，有源层厚度为100 nm的三元OSC中，实现了15.31％的最佳功率转换效率（PCE），并且还显示了78.05％的相对较高的填充因子（FF）。相对较高的FF表示在优化的三元OSC中有效的电荷传输和收集，这对于实现高效的厚膜OSC应该是有益的。突出显示PCE为14。在优化的三元OSC中，具有300 nm厚的有源层且与卷对卷（R2R）大规模打印工艺兼容的三元OSC达到了57％。迄今为止，很少有高性能厚膜三元非富勒烯OSC的报道。这项工作表明，厚膜三元策略在实现有效的大规模OSC中具有巨大的潜力。
