HySPRINT Upgraded. Joint Lab with Humboldt-Universität
The first joint lab between HySPRINT and another research institution has been established
We, team of the Helmholtz Innovation Lab HySPRINT, are continuously improving our internal resources to advance level of cooperation with the industrial partners. Last year Dr. Eva Unger and her Young Investigator Group working for the HySPRINT perovskite lab started to collaborate closely with the group “Hybrid Devices” led by Prof. Dr. Emil List-Kratochvil from the Integrative Research Institute for the Sciences (IRIS) of the Humboldt-Universität (HU) zu Berlin. Their long-term collaboration is focusing on the “Generative manufacturing processes for hybrid components”.
HU researchers find the collaboration with HySPRINT very advantageous. List-Kratochvil says: “For us HySPRINT is not only an exemplary research partner, but is a real working vehicle to move outside academia to industry.” The joint lab has recently launched a new cooperation with an Israel company “OrelTech” specializing on the metal surface coating for printed transparent electrodes.
List-Kratochvil has a great experience in fabrication of hybrid (opto)electronic devices and components via inkjet printing and coating. The group is working with various inks and have currently developed the unique sintering copper process. Intensively working on scaling, they can already print devices on the A4 format (21 x 30 cm) targeting towards larger sizes. Here, Unger’s excellent background in the formation of hybrid materials, perovskites, solar cells and their scaling, comes into play. Her group is also working on the development of solutions and inks utilized for the slot-die coating and printing.
Objectives of this research tandem are covering a wide field of topics of scaling and producing of photovoltaic and (opto)electronic components and devices. Unger’s group will concentrate on the investigation and improvement of the fabrication processes for the hybrid perovskite materials and their interfaces. List-Kratochvil and his team aim to realize the large scale printed memories, light-emitting diodes (LEDs) and transparent conductive electrodes and interconnects. For testing of the final devices the joint lab employs a large variety of electrical and spectroscopy techniques. To enhance their scientific cooperation, List-Kratochvil and Unger will set up together a new equipped working space, 200 m2 large, in October 2019.
HySPRINT and the “Hybrid Devices” teams have already developed together an assembly of the single processes and will work further on their improvement in the upcoming two years. Being at the Technology Readiness Level 3 (TRL) of production, common for the research institutions, the joint lab strives to reach TRL 6 (from 9) in the next 5 years. As a result, List-Kratochvil and Unger expect to settle the pilot line of hybrid components and large-size hybrid tandem solar cells.
HySPRINT is a strong collaborative environment based on the state-of-the-art infrastructure. We are eager to provide solutions to the R&D challenges of our industrial partners.
