The objective of this research is to explore and gain fundamental understanding of new ways to increase the power conversion efficiency of organic photovoltaic devices. The approach is to improve charge separation and transport in such devices by creating ordered nanoscale interface between an electron donor and acceptor layer in a conjugated polymer based solar cell.Intellectual Merit:Since the discovery organic photovoltaic made with bulk heterojunction polymer blend in 1995 that resulted in the relatively high efficiency, major efforts in the past many years have been developing various annealing methods to modify the heterojunction morphology as a means to improve the efficiency. It becomes evident that these approaches based on the self-organization of blend materials are reaching its limit, and a new methodology is needed to realize the theoretical efficiency for the organic photovoltaic. The most promising one is to "artificially" create the ordered nanoscale interface between the donor and acceptor layers. This program exploits a top-down nanofabrication technology that can not only produce ordered nanoscale morphology with tunable properties, but also scalable to high-throughput roll-to-roll manufacturing in the future. Broader Impacts:Power efficiency is an important factor that determines if the organic photovoltaic technology will become a viable green energy in the future. Therefore the success of this program has transformative impact on the critical fields of renewal energy, sustainable environment and the society. Both graduate and undergraduate students (including minority student) will be involved in the research. The results will be incorporated into courses offered in the EECS and MSE departments

这项研究的目的是探索并获得对提高有机光伏设备功率转换效率的新方法的基本理解。该方法是通过在基于共轭聚合物的太阳能电池中创建有序的电子捐赠者和受体层之间有序的纳米级接口来改善电荷分离和运输。以来：自从发现的有机光伏与散装异质结合聚合物在1995年相对高效的各种努力中，多年来在许多努力中产生了多种效率，这是自以来一直在发展中的各种努力，并且在许多方面发展了多种多样的效率，这是许多努力的努力。杂结形态是提高效率的一种手段。显然，这些基于混合材料的自组织的方法已达到极限，需要一种新的方法来实现有机光伏的理论效率。最有希望的是，“人为地”在捐赠者和受体层之间创建有序的纳米级接口。该程序利用了自上而下的纳米制造技术，该技术不仅可以产生具有可调性能的有序纳米级形态，而且还可以扩展到将来对高通量卷到滚动制造。更广泛的影响：功率效率是确定有机光伏技术是否将来成为可行的绿色能源的重要因素。因此，该计划的成功对更新能源，可持续环境和社会的关键领域具有变革性的影响。研究生和本科生（包括少数族裔学生）都将参与研究。结果将纳入EEC和MSE部门提供的课程
