In the first funding period we successfully developed the envisioned EPR method OTRACE-EDMR for a selective probing of photo-generated and extracted charge carriers in opto-electronic and photovoltaic devices by means of pulsed, field-induced extraction under EPR conditions. Our method determines quantitativelythe impact of spin-dependent recombination on state-of-the-art thin-film organic solar cells. In the second funding period we will apply this method to relevant material systems and devices, such as polymer-fullerene bulk-heterojunctions, organo-metallic halide perovskites, as well as carbon nanotube based photovoltaic devices.

在第一个融资期间，我们成功地开发了设想的EPR方法OTRACE-EDMR，以选择性探测光电和光伏设备中的光子生成和提取的电荷载体，并通过脉冲，现场诱导的EPR条件下的脉冲诱导的提取。我们的方法定量确定自旋依赖性重组对最先进的薄膜有机太阳能电池的影响。在第二个融资期内，我们将将这种方法应用于相关的材料系统和设备，例如聚合物 - 富集烯量 - 异源 - 官方官，有机金属卤化物钙钛矿以及基于碳纳米管的光伏设备。
