界面策略已被确定为优化聚合物太阳能电池（PSC）整体性能的有效方法。在此，三种新型的非共轭小分子，包括氨基阳离子和磺酸根阴离子，以及各种核心原子的氧，硫，和砜，被成功地合成和用作阴极夹层（CIL）的非富勒烯PSC。结果表明，溶液处理后的硫基CIL具有优异的阴极修饰能力和器件性能，最高的功率转换效率（PCE）为11.30%。与真空沉积的Ca相比，非共轭小分子CIL能显著提高Al对电极的电荷传输和收集能力，降低Al对电极的功函数（WF），降低界面处的串联电阻和电荷复合。最重要的是，这些简单的水/醇溶性CIL具有重要意义，并且适合于低成本和大面积制备PSC。
The interface strategy has been identified as an effective process to optimize the overall performance of polymer solar cells (PSCs). Herein, three novel non-conjugated small molecules comprising amino cations and sulfonate anions, as well as various core atoms of oxygen, sulfur, and sulfone, were successfully synthesized and employed as cathode interlayers (CILs) for non-fullerene PSCs. A large improvement of the device performance was observed, in which the solution processed sulfur-based CIL shows excellent cathode modification ability and device properties with the highest power conversion efficiency (PCE) of 11.30%. Compared with the vacuum deposited Ca, the non-conjugated small-molecule CILs could significantly increase the charge transport and collection capabilities, decrease the work function (WF) of the Al counter electrode, and reduce the series resistance and charge recombination at the interface. Most importantly, these simple water/alcohol soluble CILs are of great significance and suitable for the low-cost and large-area preparation of PSCs.
