a 1.8 eV band gap, and PC(61)BM:POPT bulk heterojection devices provide a peak performance of 3.1%. Additionally, an efficiency of 2.0% is achieved in an all-polymer, bilayer OPV using poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-(1-cyanovinylene)phenylene] (CNPPV) as an acceptor. This state-of-the-art all-polymer device is analyzed in comparison to the analogous poly(3-hexylthiophene) (P3HT)/CNPPV device
报道了从格氏复分解 (GRIM) 合成聚 [3-(4-n-辛基)-苯基噻吩] (POPT)。GRIM POPT 被发现对有机光伏 (OPV) 具有良好的电子、光学和加工性能。POPT 的空间电荷限制电流和场效应晶体管测量分别产生 1 x 10(-4) cm(2)/(V s) 和 0.05 cm(2)/(V s) 的空穴迁移率。从氯苯旋铸 GRIM POPT 产生带隙为 1.8 eV 的薄膜,PC(61)BM:POPT 本体异质注入装置提供 3.1% 的峰值性能。此外,在使用聚[2-甲氧基-5-(2'-乙基己氧基)-1,4-(1-氰基亚乙烯基)亚苯基] (CNPPV) 作为受体的全聚合物双层 OPV 中实现了 2.0% 的效率. 与类似的聚(3-己基噻吩)(P3HT)/CNPPV 设备相比,对这种最先进的全聚合物设备进行了分析。与基于更有利的能级排列、更大的有源层光吸收和类似的空穴迁移率的预期相反,P3HT/CNPPV
