While organic photovoltaics have experienced continued efficiency improvements in recent years, several fundamental aspects of the dominant loss mechanism, nongeminate recombination, are still not understood. The aim of the TEMET NOSCE project is to understand the role of the different aspects of charge transport in nongeminate recombination and their relationship to the morphology of the photoactive layer. Therefore, we plan to measure the recombination rate, charge carrier concentration, electron and hole mobility in a number of systematically varied samples under comparable experimental conditions. These measurements are complemented with a detailed study of the morphology of the active layer of these samples with advanced X-ray techniques. The recombination and morphology characterizations will then be combined in kinetic Monte Carlo simulations to test and develop new physical models for nongeminate recombination. This multi-methodological approach will provide the basis for a fundamental understanding of the relationship between performance, properties, and morphology in organic photovoltaics.

尽管有机光伏的效率近年来不断提高，但其主要损耗机制的几个基本方面--非链重组--仍不清楚。TEMET NOSCE项目的目的是了解电荷传输的不同方面在非线型复合中的作用及其与光活性层形态的关系。因此，我们计划在可比较的实验条件下测量一些系统变化的样品中的复合速率、载流子浓度、电子和空穴迁移率。除了这些测量之外，还用先进的X射线技术详细研究了这些样品的有源层的形态。然后，复合和形态表征将被结合在动力学蒙特卡罗模拟中，以测试和开发新的非线型复合的物理模型。这种多方法的方法将为从根本上理解有机光伏中性能、性能和形态之间的关系提供基础。
