A series of polymer solar cells (PSCs) were prepared with different solvent additive 1-chloronaphthalene (CN) doping volume ratio to adjust the phase separation of active layers. The optimized PSCs exhibit a power conversion efficiency (PCE) of 8.09%, along with an open-circuit voltage of 1.01 V, a short circuit current density of 13.64 mA cm–2, and a fill factor of 58.70%. All the key photovoltaic parameters of PSCs can be simultaneously increased by incorporating 1.0 vol % CN in blend solutions due to the optimized phase separation of active layers assisted by the volatilization of CN. Over 24% PCE improvement can be obtained by incorporating 1.0 vol % CN, indicating that the dynamic process of film forming should play the vital role in determining the performance of PSCs.

高效聚合物太阳能电池,开路电压为 1.01 V,功率转换效率为 8.09%

采用不同溶剂添加剂1-氯萘(CN)掺杂体积比来调节有源层的相分离,制备了一系列聚合物太阳能电池(PSC)。优化后的PSC的功率转换效率(PCE)为8.09%,开路电压为1.01 V,短路电流密度为13.64 mA cm –2,填充因子为58.70%。通过在混合溶液中加入 1.0 vol% CN,可以同时提高 PSC 的所有关键光伏参数,因为 CN 挥发有助于优化活性层的相分离。通过加入1.0 vol% CN可以获得超过24%的PCE改善,这表明成膜的动态过程在决定PSC的性能方面发挥着至关重要的作用。
