In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Sarah Tolbert, Yves Rubin, and Benjamin Schwartz of the University of California at Los Angeles will develop methods for the solution-phase self-assembly of fullerene derivatives and conjugated polymers into films for organic solar cells. The research has three complementary components. In the first part, the research will focus on the use of molecular assembly in self-complementary fullerene derivatives to optimize network architecture for increased electron mobility. In the second part, carrier mobility in the semiconducting polymer will be examined and optimized, this time using self-assembly of amphiphilic semiconducting polymers in aqueous solution. Finally, to facilitate the use of high mobility electron acceptors such as titania, fullerenes with surface binding groups will be prepared and the performance of solar cells incorporating nanostructured titania covered with fullerene monolayers will be studied. The broader impacts involve training graduate and undergraduate students, enhancing research infrastructure by bringing together a collaborative group, conducting high school teacher workshops on solar cells/solar energy, and the potential societal benefits of inexpensive organic photovoltaic devices.Solar cells made from electrically conducting plastics show great technological promise but have significant drawbacks in terms of low efficiencies and irreproducibility in processing. This research seeks to solve some of those problems by enhancing our fundamental understanding of how to integrate various organic compounds to capture light and turn it into electrical energy. The specific focus is to find robust ways to create nanometer sized structures that can efficiently generate electricity and then transport that electricity out of the solar cell for usage. Through development of new chemical components and processing strategies, this research could lead to easier to produce and less expensive solar cell technologies.

在该项目中由化学部的大分子，超分子和纳米化学计划资助，洛杉矶分校的加利福尼亚大学的萨拉·托尔伯特，伊夫·鲁宾和本杰明·施瓦茨将开发用于富勒烯衍生物和有机胶片的溶液相层自组合的方法的方法。 该研究具有三个互补组成部分。 在第一部分中，该研究将集中于在自融合富勒烯衍生物中使用分子组装来优化网络体系结构以提高电子迁移率。 在第二部分中，将检查和优化半导体聚合物中的载流子迁移率，这次使用水溶液中的两亲性半导体聚合物的自组装。最后，为了促进使用高迁移率电子受体（例如二氧化钛），将准备具有表面结合基团的富勒烯，并将研究融合了纳米结构的二氧化钛覆盖富勒烯单层的太阳能电池的性能。更广泛的影响涉及培训毕业生和本科生，通过将一个协作小组组合在一起，进行有关太阳能电池/太阳能/太阳能的高中教师讲习班以及廉价的有机光伏设备的潜在社会益处来增强研究基础设施。在质量指导下，塑料能力较低，但在较低的过程中，有机型塑料能够在较低的过程中获得良好的绘图，但在较低的水平上均具有良好的绘制，但具有良好的水平和IRICEIS的功能。 这项研究旨在通过增强我们对如何整合各种有机化合物以捕获光并将其转化为电能的基本理解来解决其中的一些问题。 具体的重点是找到可靠的方法来创建纳米尺寸的结构，以有效地发电，然后将电力从太阳能电池牢房中传输出来。 通过开发新的化学组件和加工策略，这项研究可能会导致更容易生产和便宜的太阳能电池技术。
