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.

在第一个资助期内，我们成功开发了预期的EPR方法OTRACE-EDMR，用于在EPR条件下通过脉冲场诱导提取选择性探测光电和光伏器件中的光生和提取电荷载流子。我们的方法定量地确定了自旋相关复合对最先进的薄膜有机太阳能电池的影响。在第二个资助期内，我们将把这种方法应用于相关的材料系统和器件，如聚合物-富勒烯体异质结，有机金属卤化物钙钛矿，以及基于碳纳米管的光伏器件。
