Since August 2018, the HZB group of Dr. Eva Unger (Hybrid Materials Formation and Scaling), who are based in the HySPRINT perovskite lab, and the group of Prof. Dr. Emil List-Kratochvil (Hybrid Devices) from the Integrative Research Institute for the Sciences (IRIS) of Humboldt-Universität zu Berlin (HU Berlin), have cooperated on the long-term project “Generative manufacturing processes for hybrid components” (GenFab).

List-Kratochvil and Unger develop large scale (opto)electronic devices, printed solar cells and components fabricated by printing and solution-based methods from hybrid materials: from transparent conductive electrodes to memory devices, transistors, light-emitting diodes, solar cells and sensor applications.

To enforce the synergy between the research groups, they decided to establish a new jointly used lab space for GenFab based in the new IRIS research building. The joint research place will open in summer/autumn 2020.

Hybrid Materials Formation and Scaling (HZB)

The Young Investigator Group of Dr. Eva Unger develops scalable deposition methods for fabrication of large scale hybrid and perovskite-based photovoltaic devicesis, using the HySPRINT perovskite lab facilities.

Hybrid Devices (HU)

The group of Prof. Dr. Emil List-Kratochvil performs:

  • coating and inkjet printing using various inks, e.g. metal nanoparticles such as silver and copper;
  • fabrication of the devices up to A4-scale (21 x 30 cm);
  • structural and morphological characterisation of the final components and devices via scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS)
  • optical and electrical investigations by means of luminance / current / voltage measurements, four-point conductivity (see the photo), external quantum efficiency and others.

    More details on the availabale methods and research progress of the "Hybrid Devices" group can be found here.
