DI Dr. Thomas Rath

Thomas Rath studied Industrial Chemistry at Graz University of Technology. In 2008, he completed his PhD focusing on hybrid nanomaterials for solar cell applications at the Institute for Chemistry and Technology of Materials under the supervision of Prof. Franz Stelzer. After that, he joined the Christian Doppler Laboratory for Nanocomposite Solar Cells headed by Prof. Gregor Trimmel as postdoctoral research associate. Within this industry-driven research project, his focus was on the development of roll-to-roll processable materials for polymer/nanoparticle hybrid solar cells and the optimization of the materials and solar cells regarding power conversion efficiency and stability.

From 2013-2015 he was a postdoctoral research associate in the group of Dr. Saif Haque at Imperial College London (Department of Chemistry and Centre for Plastic Electronics) working on the Erwin Schrödinger Fellowship Project “Chemical Interface Tailoring in Hybrid Solar Cells” funded by the Austrian Science Fund (FWF).

Since end of 2015, he is continuing his research on solution processable hybrid solar cells at ICTM at Graz University of Technology.

His main research interests include:

  • Non-toxic absorber materials for solar cell applications (novel solution-based synthesis routes, X-ray scattering-based characterisation, growth kinetics)
  • Precursor-based synthesis of semiconducting metal sulfide films for PV applications and their characterisation
  • In situ preparation routes towards polymer/nanocrystal films for hybrid solar cells
  • Lead-free perovskite-based solar cells (including stability and degradation mechanisms)
