Doping and charge transport processes in organic and hybrid materials for energy applications

Doping and charge transport are key processes to enhance electrical, thermal and optical functions in organic and hybrid materials. They underpin emerging energy saving and bioelectronic devices. The symposium will bring together key investigators to discuss challenges and perspectives of widespread applications of organic and hybrid electronics.

Scope:

Scope of the symposium is to bring together the experimental and theoretical communities to discuss new challenges and perspectives in the areas of doping and charge transport processes in organic and hybrid functional materials. Such themes have been the subject of in-depth investigations in the past, however new findings are challenging the traditional structure-property paradigms, which have been driving the materials design and modeling up to now. The doping mechanisms and the role of dopants in governing the structural and functional properties of either high-charge carrier mobility polymers or perovskites is not well understood yet. New molecular-design methods, dopants and doping techniques are continuously enhancing the values of parameters such as the electrical conductivity, Seebeck coefficient and redox activities, paving the way for organic and hybrid materials to emerging applications such as thermoelectric, supercapacitors and bioelectronic devices.

Great challenges still have to be faced, mainly regarding:

Materials Synthesis

  1. Design and synthesis of new organic semiconductors including both small molecule and polymeric conjugated materials
  2. Design and synthesis of new dopant systems
  3. Design and synthesis of new hybrid materials

Materials and Device Characterization

  1. Fundamental understanding of the various doping mechanisms
  2. Overcome limited processability and control over the microstructure of doped films
  3. Fundamental understanding of the intrinsic chemical instability of n-doped films

Materials Modeling

  1. Modeling morphology and structural properties of doped organic and hybrid materials.
  2. Modeling the spectroscopic properties of doped organic and hybrid materials.
  3. Understanding charge and thermal transfer dynamics in functional materials via multi-scale first principles simulations.

  • Fundamental mechanisms of bulk and interface doping.
  • Structural, optical, electronic, and thermoelectric properties of doped organic and hybrid materials.
