A5: Correlative Electron Microscopy and Optical Spectroscopy for Accelerated Organic Solar Cell Design
Correlative Electron Microscopy and Optical Spectroscopy for Accelerated Organic Solar Cell Design
This doctoral project aims to integrate microscopic structure information into automated materials optimization workflows for organic solar cells (OSCs). Building on an existing autonomous thin-film processing and characterization platform (AMANDA), the candidate will combine optical spectroscopy with high-resolution electron and X-ray diffraction techniques to establish direct correlations between microstructure and device performance. Structural descriptors derived from microscopy will be incorporated into AI- and physics-based models to improve predictive power and enable data-driven materials design. A key objective is to qualify optical spectroscopy as a fast, non-destructive proxy for microscopic structure. The work will involve developing dose-efficient data fusion strategies to mitigate beam damage and exploit sparse data effectively. The resulting workflow will enhance materials discovery by linking structure, processing, and performance in an interpretable and scalable way, supporting broader CorMic research on functional thin films.
