Development of novel organic semiconductors and advanced combinatorial characterization methods for high performance, printable polymer solar cells

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，当前技术水平的有机半导体的性能、可加工性和稳定性不能很好地平衡到一组材料中的成品率性能和环境稳定性。大多数出版物要么报道稳定的材料复合材料，要么报道高效材料复合材料。需要开发新的材料，更重要的是，需要为克服当前损失的材料类别制定新的设计规则。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及其与材料和工艺相关的微结构导致的退化机制。这项提议的目标是开发新的材料类别，允许解决已知的微结构导致的退化损失，实现可靠的加工，并在一个复合材料中结合性能和寿命。华南理工大学和FAU靶标的这项协同研究工作，首次携手开发高性能和高稳定性材料。通过现场测试和高通量测试相结合的方法，将有效地筛选和探索新的材料类别。有机光伏器件的展示具有超过12%的PCE和超过10年的出色运行寿命(在加速条件下测量)，是该项目的最后一个里程碑。

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.
