The synthesis, device fabrication, and electric poling of novel amino-functionalized fulleropyrrolidines in polymer solar cells is reported. Systematically varying the tether lengths between the fullerene cage and tertiary amines provides insight into enhanced device efficiency and stability after poling. DFT calculations in an external electric field result in alignment of molecular dipole moments, which corroborates our hypothesis that electrotropic polarization causes an increased built-in electrostatic potential difference across the device, and results in enhance performance.

氨基-全氟吡咯烷类作为电助剂，可增强有机光伏

报道了聚合物太阳能电池中新型氨基官能化的全吡咯烷的合成，器件制造和电极化。系统地改变富勒烯笼和叔胺之间的系链长度，可以深入了解极化后增强的设备效率和稳定性。在外部电场中进行DFT计算会导致分子偶极矩对齐，这证实了我们的假设，即电偏极化会导致整个设备的内置静电势差增加，从而提高性能。
