Solar energy is a promising means of addressing global warming and the ever-increasing demand for energy. However, there are many open questions for current solar materials. Electron microscopy is a powerful tool to understand the structure-property relationship for solar materials. SEM-electron beam induced current (EBIC) maps the electron-hole carrier collection efficiency. Aberration corrected STEM equipped with spectroscopy reveals the atomic structure and chemical compositions of defects. Moreover, in-situ heating microscopy allows us to directly probe growth-structure correlations. Combining all these techniques, growth-structure-property correlations can be understood, which will open the door to achieving high performance low cost solar cells.
Dr. Li received a B.Sc. in Materials Physics from Wuhan University and a Ph.D. in Condensed Matter Physics from the Institute of Physics, CAS. In 2012 she took a postdoc position at Oak Ridge National Laboratory USA, using STEM to study defects in solar cells. In 2014 she moved to University of Vienna where she received an EU Marie Curie fellowship. She is currently working at the Max Planck Institute Stuttgart, combining multi-scale electron microscopy to understand solar materials.
