Abstract Three conjugated polyelectrolytes(CPEs) based on thiophene, thieno[3,2-b]thiophene, and 2,2'-bithiophene were designed and synthesized. The CPEs were successfully incorporated into polymer solar cells as pH-neutral hole-transporting layer(HTL) via solution process. The interfacial dipole and work function(WF) of CPE-coated ITO were controlled by the dipole moment of the polymer, which was in turn determined by the stereochemical properties of the molecular structure. CPE-coated ITOs showed sequentially stronger dipole moments due to an increase in the electrostatic repulsion in the molecules. The PCE of device with PFT as the HTL was maintained accompanied by 16% decrease when PEDOT:PSS-based device decreased over 50%.

通过改变聚电解质的分子构象增强空气稳定性和优化 V OC

摘要 设计合成了噻吩、噻吩并[3,2-b]噻吩和2,2'-联噻吩三种共轭聚电解质(CPEs)。CPE通过溶液工艺成功地作为pH中性空穴传输层（HTL）并入聚合物太阳能电池中。CPE包覆ITO的界面偶极子和功函数(WF)受聚合物偶极矩控制，而聚合物偶极矩又由分子结构的立体化学性质决定。由于分子中静电排斥的增加，CPE 涂层的 ITO 显示出更强的偶极矩。当基于 PEDOT:PSS 的设备下降超过 50% 时，以 PFT 作为 HTL 的设备的 PCE 保持不变，同时下降 16%。
