A novel n‐type polymer of PTDI‐T based on asymmetric rylene diimide and thiophene is designed and synthesized. The highest power conversion efficiency of 4.70% is achieved for PTB7‐Th:PTDI‐T‐based devices, which is obviously higher than those of the analogue polymers of PPDI‐2T and PDTCDI. When using PBDB‐T as a donor, an open‐circuit voltage (V_OC) as high as 1.03 V is obtained. The results indicate asymmetric rylene diimide is a kind of promising building block to construct n‐type photovoltaic polymers.

一种基于不对称亚芳基二酰亚胺的新型n型聚合物的设计与合成，用于全聚合物太阳能电池

设计并合成了一种基于不对称亚芳基二酰亚胺和噻吩的新型PTDI-T n型聚合物。基于PTB7-Th：PTDI-T的设备实现了最高4.70％的功率转换效率，明显高于PPDI-2T和PDTCDI的类似聚合物。当使用PBDB-T作为施主时，可获得高达1.03 V的开路电压（V _OC）。结果表明，不对称的二甲苯基二酰亚胺是构造n型光伏聚合物的一种有前途的构建基块。
