摘要

有机半导体中的载流子迁移率不是一个明确表征某种特定材料的恒定值,而是取决于电场、温度,甚至在产生或注入后的时间。对于载流子在迁移率达到固定值之前通过有机层的薄膜器件,时间依赖性尤为重要。在这里,我们回顾了超快时间分辨率的实验技术,使人们能够解决迁移动力学和分析共轭聚合物和有机太阳能电池中随时间迁移的性质。我们分析了载流子产生和自由载流子提取过程中的动力学。在皮秒-纳秒的时间尺度上,迁移率通常会降低几个数量级;然而,其动力学也取决于研究技术。体异质结太阳能电池共混物的迁移动力学在很大程度上取决于供体和受体材料的化学计量比。

Charge carrier mobility dynamics in organic semiconductors and solar cells
Charge carrier mobility in organic semiconductors is not a constant value unambigously characterizing some particular material, but depends on the electric field, temperature and even on time after it was generated or injected. The time dependence is particularly important for the thin-film devices where charge carriers pass the organic layer before mobility reaching its stationary value. Here we give a review of experimental techniques with ultrafast timeresolution enabling one to address the mobility kinetics and analyse properties of the time-dependent mobility in conjugated polymers and organic solar cells. We analyse kinetics during the charge carrier generation and extraction of free charge carriers. The mobility typically decreases by several orders of magnitude on a picosecond-nanosecond time scale; however, its kinetics also depends on the investigation technique. The mobility kinetics in blends for bulk heterojunction solar cells strongly depends on the stoichiometric ratio of donor and acceptor materials.
