The International Research Fellowship Program enables U.S. scientists and engineers to conduct nine to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award is co-funded by the Office of International Science and Engineering and by the Electronics, Photonics and Magnetic Devices Program in the Electrical, Communications and Cyber Systems Division. This award will support a twelve-month research fellowship by Dr. Neil D. Treat to work with Dr. Natalie Stingelin at Imperial College London in London, United Kingdom. One of society's challenges is to develop a clean, renewable, and sustainable energy source. Organic photovoltaics (OPVs) offer great potential as a low-cost solution to this need because of their ability to be solution processed over large areas. Currently, OPVs are approaching the estimated 10% power conversion efficiency needed to achieve economic viability, but further improvement and large area utilization is predicated on a deeper understanding of how to control their complex microstructure and how this affects the device performance. Thus, gaining control over the blend microstructure is of utmost importance for the continued technological development of OPVs so that they may be realized as a renewable and sustainable energy source. This project is currently developing strategies to control the microstructure of OPVs materials through the addition of additives. This strategy provides a means to control the active layer microstructure, which can be used to further both our fundamental and practical understanding of this system. Specifically, this project is using nucleating agents - additives that control the microstructure of semicrystalline polyolefins - to control the ordering in OPV materials and to correlate this change to their electronic properties. The main goal of this project is to link the changes in the molecular ordering of neat polymer based devices to the electronic performance and understanding how the polymer architecture can influence the efficiency of nucleation and the resulting electronic properties. The second portion involves extending this understanding to develop processing strategies for large area coating. Indeed, the use of nucleating agents is an unexplored, but potentially useful strategy for controlling the microstructure of OPV materials.

国际研究奖学金计划使美国的科学家和工程师能够在国外进行九至二十四个月的研究。该计划的奖项为联合研究提供了机会，以及在国外使用独特或补充设施，专业知识和实验条件。该奖项由国际科学和工程办公室以及电气，通信和网络系统部门的电子，光子和磁设备计划共同资助。 该奖项将支持Neil D. Treat博士的十二个月研究奖学金，与英国伦敦帝国伦敦帝国学院的Natalie Stingelin博士合作。社会的挑战之一是开发清洁，可再生和可持续的能源。有机光伏（OPV）具有巨大的潜力作为对这种需求的低成本解决方案，因为它们能够在大面积上处理解决方案。目前，OPV正在接近实现经济生存能力所需的10％功率转换效率，但是进一步的改进和大量领域的利用是基于对如何控制其复杂的微观结构以及如何影响设备性能的更深入了解。因此，获得对混合微观结构的控制对于OPV的持续技术发展至关重要，因此可以将它们实现为可再生和可持续的能源。该项目目前正在开发通过添加添加剂来控制OPVS材料微观结构的策略。该策略提供了一种控制主动层微观结构的方法，可以用来进一步进一步了解我们对该系统的基本和实际理解。具体而言，该项目使用了成核剂 - 控制半稳定聚集蛋白的微观结构的添加剂 - 控制OPV材料中的顺序，并将这种变化与其电子特性相关联。该项目的主要目的是将基于聚合物的设备的分子排序的变化与电子性能联系起来，并了解聚合物结构如何影响成核的效率和所得的电子特性。第二部分涉及扩展这种理解以制定大面积涂层的处理策略。实际上，使用成核剂是一种无法探索的，但可能有用的策略来控制OPV材料的微观结构。
