项目摘要

This project aims at the development and experimental validation of a numerical model for describing charge carrier dynamics in organic semiconductor layers and hetero-structures, which is then applied to organic photovoltaic cells and organic light-emitting diodes (OLEDs). The motivation is to shed light on the dynamic charge transport and recombination processes in these organic optoelectronic devices. While a lot of research was already performed on charge transport in single-layer organic semiconductor devices, multilayer and/or stacked organic semiconductor devices are not yet fully understood. However, multilayer and/or stacked device architectures are crucial for high-efficiency OLEDs and organic solar cells. The latter device can either be built in a planar or bulk hetero-junction geometry of the two active semiconductor components.We plan to employ a combination of steady-state and transient opto-electronic characterization methods both in experiment and simulation. In this lead-agency project between Germany and Switzerland, we have the unique opportunity to resolve the challenging physical questions related to the operating mechanisms governing these novel devices in terms of efficiency and lifetime by dedicated device fabrication as well as measurement and simulation based characterization.

该项目旨在开发和实验验证用于描述有机半导体层和异质结构中电荷载流子动力学的数值模型，然后将其应用于有机光伏电池和有机发光二极管（OLED）。其动机是阐明这些有机光电器件中的动态电荷传输和复合过程。虽然已经对单层有机半导体器件中的电荷传输进行了大量研究，但多层和/或堆叠的有机半导体器件尚未完全理解。然而，多层和/或堆叠的器件架构对于高效OLED和有机太阳能电池是至关重要的。后一种器件既可以采用平面结构，也可以采用两个有源半导体器件的体异质结结构，我们计划在实验和模拟中采用稳态和瞬态光电特性的结合方法。在这个德国和瑞士之间的牵头机构项目中，我们有独特的机会通过专门的器件制造以及基于测量和模拟的表征来解决与这些新型器件的效率和寿命有关的操作机制相关的具有挑战性的物理问题。
