项目摘要

Organic semiconductors have an enormous potential for renewable energy applications, in particular for green photovoltaic electricity production. However, the performance, processability and stability of the current state of the art organic semiconductors are not well balanced to yield performance and environmental stability within one set of materials. Most publications report on either stable or efficient material composites. Novel materials and, even more important, novel design rules for material classes overcoming the current losses need to be developed. Most importantly, these novel design rules need to better balance the performance of organic electronic devices with their materials- and processing-related microstructure induced degradation mechanisms. This proposal targets to develop novel materials classes allowing to tackle the known microstructure induced degradation losses, enable reliable processing and to combine performance and lifetime within one composite. This synergistic research effort between SCUT and FAU targets, for the first time, developing high performance and high stability materials hand in hand. Novel material classes will be efficiently screened and explored by a combination of in-situ and high throughput testing methods. The demonstration of organic photovoltaic devices with a PCE of over 12% and excellent operational lifetime of over 10 years (measured under accelerated conditions) is the final milestone of this project.

有机半导体在可再生能源应用方面具有巨大潜力，特别是在绿色光伏发电方面。然而，现有技术的有机半导体的性能、可加工性和稳定性不能很好地平衡以在一组材料内产生性能和环境稳定性。大多数出版物报道稳定或有效的材料复合材料。需要开发新的材料，更重要的是，需要开发克服电流损耗的材料类别的新设计规则。最重要的是，这些新的设计规则需要更好地平衡有机电子器件的性能与其材料和加工相关的微结构诱导的降解机制。该提案旨在开发新型材料类别，以解决已知的微结构引起的降解损失，实现可靠的加工，并在一种复合材料中结合联合收割机性能和寿命。SCUT和FAU之间的协同研究工作首次携手开发高性能和高稳定性材料。新型材料类别将通过现场和高通量测试方法的组合进行有效筛选和探索。该项目的最后一个里程碑是展示PCE超过12%、使用寿命超过10年（在加速条件下测量）的有机光伏器件。
