摘要

以聚3-已基噻吩(P3HT)和聚对苯亚乙烯衍生物(MDMO-PPV)作为电子给体

聚 (TQ1)作为电子受体

制备并研究了聚合物给体/聚合物受体有机光伏电池性能。当给体P3HT、受体TQ1共混质量比为1∶1时

器件性能最佳。热处理会改变薄膜形貌

导致激子扩散到达界面的距离增加和激子分离界面数量下降

进而引起器件性能下降。溶剂效应对器件性能影响不明显。研究了相似能带结构给体聚合物对MDMD-PPV光电池性能的影响

发现结晶程度较低的给体材料会进一步导致器件性能降低。

Abstract

Organic bulk-heterojunction solar cells were prepared using two conjugated polymers(P3HT

MDMO-PPV) as electron donor

respectively

and a conjugated polymer (TQ1)as electron acceptor. The best performance was achieved with the mass stoichiometry of 1∶1. It is found that thermal annealing has a pronounced effect on device performance. Annealing can alter the morphology of active layer

which results in the increase of distance for exciton diffusion and the decrease of interface area for exciton separation

leading to the decrease device performance. It is observed that solvent has little effect on device performance

which is different from fullerene-based polymer solar cells. Moreover

it demonstrated that crystallinity of donor polymer also has a significant effect on device performance

despite of similar LUMO and HOMO energy bands.
