We advance the modeling, characterization, and control of defects in solar cells and the development of new materials and device architectures for solar energy storage. Our characterization includes a significant focus on synchrotron-based microscopy and spectroscopy to elucidate material kinetics in energy materials. We also pursue the development of material processing simulation tools to answer precisely and in a predictive manner the processing path of synthesizing functional materials into highly-functional devices.
