Latest innovations in inkjet printing of metal-halide perovskite devices at a glance


A new work performed in the GenFab Lab of the Helmholtz Innovation Lab HySPRINT gives a comprehensive overview of the recent advances in the production of inkjet-printed metal halide perovskites (MHPs) for optoelectronic devices and their applications. Inkjet-printing is a reliable production technology already used in many industrial sectors from graphics to medicine and printed electronics.

Dr. Florian Mathies from GenFab, first author of the paper, says, “Manufacturing of the MHPs via inkjet printing is very promising for the industrial application. This technology is flexible, digital, cost-effective and highly controllable. We show that the fabrication of efficient MHP-based devices is possible with the combination of appropriate inks, substrates and printing parameters.” Indeed, the efficiency of inkjet-printed MHP-based solar cells now is almost 21%. The authors foresee that MHP devices fabricated by inkjet-printing can be scaled up to commercial size paving the way towards their extensive production. Read the full article here> 

HySPRINT hosts University of Cambridge for workshop on inkjet printing


In November 2019, Dr. Florian Mathies and Dr. Felix Hermerschmidt from the joint lab GenFab of Dr. Eva Unger (HySPRINT) and Prof. Emil List-Kratochvil (Humboldt Universität zu Berlin) hosted a three-day workshop on inkjet printing for collaborators at the University of Cambridge.

Our four participants of Prof. George Malliaras’ Bioelectronics Laboratory obtained insights into the basic theory of inkjet printing, its applications and plenty of hands-on practical experience in the areas of ink development, printing and data evaluation. Together they identified the specific requirements of printing for bioelectronic applications and framed guidance on tailoring the inkjet process for use with the system in the lab at Cambridge.

It was a pleasure for our HySPRINT experts’ team to host the collaborators of the Bioelectronics Laboratory and to provide an insight into state-of-the art inkjet printing!

We look forward to further fruitful exchange and intensive cooperation in the future.

New highly efficient perovskite/silicon tandem solar cells presented at the PSCO-2019 conference


Recently, the researchers from the Young Investigator Group for perovskite tandem solar cells headed by Prof. Steve Albrecht have fabricated a novel perovskite/silicon tandem solar cell. The scientists implemented various modifications developed in the perovskite lab of the Helmholtz Innovation Lab HySPRINT, i.e.: precise interface engineering and the use of a self-assembled monolayer (SAM) hole transport material in the perovskite top cell. As a result, of these optimizations, the researchers gained 27.5% power conversion efficiency (PCE) - the highest PCE among the research institutions.

Eike Köhnen has presented this outcome at the Perovskite Solar Cells and Optoelectronics (PSCO-2019 [1]) conference in Lausanne, Switzerland. High practical interest of the topic and further improvements stimulated interesting questions and intensive discussion from the conference audience.
