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科学家和工程师能够在国外进行9到24个月的研究。该项目的奖项提供了联合研究的机会，并提供了使用国外独特或互补的设施、专业知识和实验条件的机会。该奖项由国际科学与工程办公室和电气、通信和网络系统部门的电子、光子学和磁性设备计划共同资助。这一奖项将支持Neil D.Treat博士与Natalie Stingelin博士在英国伦敦帝国理工学院合作的为期12个月的研究奖学金。社会面临的挑战之一是开发一种清洁、可再生和可持续的能源。有机光伏(OPV)作为一种低成本的解决方案提供了巨大的潜力，因为它们能够在大范围内进行溶液处理。目前，OPV正在接近实现经济可行性所需的10%的功率转换效率，但进一步的改进和大面积利用取决于对如何控制其复杂的微结构以及这如何影响器件性能的深入了解。因此，对共混物微观结构的控制对于OPV的持续技术发展至关重要，从而使其成为一种可再生和可持续的能源。该项目目前正在制定策略，通过添加添加剂来控制OPVs材料的微观结构。这一策略提供了一种控制有源层微观结构的手段，可以用来加深我们对该系统的基本和实际理解。具体地说，该项目正在使用成核剂--控制半结晶聚烯烃微结构的添加剂--来控制OPV材料的有序性，并将这种变化与其电子性能相关联。该项目的主要目标是将基于纯聚合物的器件的分子有序性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效率和由此产生的电子性能。第二部分涉及扩展这一理解，以开发大面积涂层的处理策略。事实上，使用成核剂是控制OPV材料微结构的一种未被探索但潜在有用的策略。
