Advanced characterization of organic and hybrid materials

Understanding the doping and charge transport in organic semiconductors and hybrid perovskites is far from trivial due to the complex interplay between structure and optoelectronic properties. Therefore, it requires developing advanced and novel characterization techniques, which are the focus of the present symposium.


Past research on conjugated organic materials (COMs) and organic-inorganic hybrid perovskite materials (OHPMs) revealed that understanding the fundamental physical processes in such materials often requires significantly adapting concepts which are otherwise well-established in inorganic semiconductor physics. Key phenomena such as doping related charge transfer, charge transport, exciton generation and dissociation as well as the role of anisotropy and microstructure are currently intensively studied and still not fully explained today. Increasing our understanding of these phenomena is, however, of utter importance both for fundamental science and any future application of COMs and OHPMs in novel technology based thereon. Clearly, this requires advanced characterization techniques to be developed and tailored to the particularities of these materials, both in experiment and theoretical modeling. The present symposium aims at stimulating an interdisciplinary discourse on advanced characterization techniques for COMs and OHPMs by bringing together current theoretical and experimental standpoints from physics, chemistry, and materials science. It further strives to discuss new developments, challenges, and perspectives in this field which arise from these techniques. The symposium addresses (but is not limited to) advanced characterization techniques that target structural, electronic, phononic, electrical, and thermoelectrical properties both theoretically and experimentally. A special focus lies on experimental techniques as performed at large scale research facilities such as synchrotron radiation sources and on the role of novel approaches in material science based on machine learning.

  • Interface and bulk doping in conjugated organic materials and hybrid perovskites
  • Charge-transfer processes at organic and hybrid heterojunctions
