Dr. Dai Zhang, Ph.D., MSc is a Group Leader at the Eberhard Karls University of Tubingen. She completed her Doctor of Philosophy at Nanjing University and her Master of Science at the Henan Normal University. Zhang's junior research group is tip-enhanced Raman and fluorescence spectroscopy, spatially resolved spectroscopy, near-field microscopy of organic semiconductors, and plasmonics. Her main research interests include the investigation of the morphology with regard to the 'bulk-heterojunction' efficiency of organic solar cells, as well as the charge transfer process in dye-sensitized solar cells.
