The aim of the PhD project is to develop new, electrically switchable materials for solar energy generation by exploiting advanced techniques in Structural Chemistry to understand the crucial relationships between the structural and functional properties of the materials of interest. In particular, the research project will combine time-resolved (TR) experimentation, in which fast processes are studied in real time, with state-of-the-art X-ray diffraction (XRD) facilities that allow rapid data collection and accurate structure determination, and the project will exploit a globally unique lab-based TR-XRD instrument that is being developed by our research team. The ultimate aim is to apply this instrumentation to create "molecular movies" in which the switching processes are observed through changes in the 3D crystal structure as a function of time, leading to a detailed mechanistic understanding of the structural features responsible for switching, and facilitating the development and optimization of the materials of interest for applications in next-generation solar cells.The student will focus on electrically switchable crystals designed within the team and will use the TR-XRD instrument to establish the structural changes responsible for electrical switching, yielding new insights into the switching mechanisms. This knowledge will be fed back into materials design, leading to optimization of the materials for enhanced properties in solar harvesting. Through this research, the student will play a crucial role in the development of the new TR-XRD instrument in Cardiff and will also have the opportunity to be involved in the design of auto-processing and control procedures to enhance the efficient operation of the instrument. The research project will also include a complementary programme of TR-XRD experiments at Diamond Light Source (the UK synchrotron radiation facility), giving the student significant experience of carrying out research at a national research facility.

博士项目的目的是通过利用结构化学中的先进技术开发用于太阳能发电的新型电开关材料，以了解感兴趣材料的结构和功能特性之间的关键关系。特别是，该研究项目将结合联合收割机时间分辨（TR）实验，其中快速过程在真实的时间进行研究，与最先进的X射线衍射（XRD）设施，允许快速数据收集和准确的结构测定，该项目将利用全球独特的实验室为基础的TR-XRD仪器，正在开发由我们的研究团队。最终目的是应用这种仪器来创建“分子电影”，其中通过3D晶体结构随时间的变化来观察开关过程，从而对负责开关的结构特征进行详细的机械理解，并促进开发和优化感兴趣的材料，用于下一阶段的应用-学生将专注于团队内设计的可电开关晶体，并将使用TR-XRD仪器来建立负责电气开关的结构变化，从而对开关机制产生新的见解。这些知识将反馈到材料设计中，从而优化材料，以增强太阳能收集的性能。通过这项研究，学生将在卡迪夫新的TR-XRD仪器的开发中发挥至关重要的作用，也将有机会参与自动处理和控制程序的设计，以提高仪器的有效运行。该研究项目还将包括在钻石光源（英国同步辐射设施）进行TR-XRD实验的补充计划，为学生提供在国家研究设施进行研究的重要经验。
