Non-fullerene acceptors have recently been used in polymer-blend photovoltaic devices to achieve power conversion efficiencies that now exceed 12%. In this project, the student will characterize a range of new acceptor materials synthesized or supplied by Ossila Ltd, and provide data regarding their optimized performance in both photovoltaic and transistor devices. This data will be used on Ossila's website, as part of the quality assurance of the materials and for content marketing of a series of new commercial products. The student will also undertake detailed characterization measurements of the nanostructure of polymer:acceptor films to understand the role of molecular morphology on device performance. The student will also explore the use of various coating techniques to deposit PV-applicable thin films.

非富勒烯受体最近已被用于聚合物共混光伏器件中，以实现目前超过 12% 的电力转换效率。在该项目中，学生将表征 Ossila Ltd 合成或提供的一系列新型受体材料，并提供有关其在光伏和晶体管器件中优化性能的数据。这些数据将在 Ossila 的网站上使用，作为材料质量保证的一部分以及一系列新商业产品的内容营销。学生还将对聚合物纳米结构进行详细的表征测量：受体薄膜，以了解分子形态对器件性能的作用。学生还将探索使用各种涂层技术来沉积适用于光伏的薄膜。
