The new Young Investigator Group Hy-Per-FORME led by Dr. Eva Unger is working on scaling all processing steps to enable manufacturing of perovskite solar cells on larger areas, thus brigding he gap between lab and industry.

Dr. Eva Unger is starting a Young Investigator Group (YIG) at HZB, co-financed by the Federal Ministry for Education and Science (BMBF). The activities of the Unger group will be an important contribution within the newly-founded HySPRINT Innovation lab aiming at the realization of large-area, stable and efficient hybrid tandem device technology based on a combination of established silicon photovoltaic technology and emerging perovskite semiconductor devices.

To achieve this goal, developing and optimizing scalable deposition methods for the recently evolved hybrid perovskite semiconductors is one of the key aspects. The YIG of Unger therefore focusses on the formation and scaling the deposition of hybrid perovskite semiconductors using slot-die coating and ink-jet printing as a solution-based processing technology.

Originally from Germany, Eva Unger did her PhD at Uppsala University, Sweden and carried out postdoctoral work at Stanford University and Lund University through a stipend from the swedish Marcus and Amalia Wallenberg Foundation. Prior to starting the YIG, she has been working as a visiting researcher at Helmholtz Center Berlin funded by an International Career Grant co-funded by the Swedish Research Council and Marie-Skłodowska-Curie Actions. She will be co-affiliated with Lund University, Sweden and aims to strengthen cooperations with Lund University, Vrije Universiteit Amsterdam and the Universities in Berlin and Brandenburg.

    Watching indium phosphide at work
    Indium phosphide is a versatile semiconductor. The material can be used for solar cells, for hydrogen production and even for quantum computers – and with record-breaking efficiency. However, little research has been conducted into what happens on its surface. Researchers have now closed this gap and used ultra-fast lasers to scrutinise the dynamics of the electrons in the material.

    Freeze casting - a guide to creating hierarchically structured materials
    Freeze casting is an elegant, cost-effective manufacturing technique to produce highly porous materials with custom-designed hierarchical architectures, well-defined pore orientation, and multifunctional surface structures. Freeze-cast materials are suitable for many applications, from biomedicine to environmental engineering and energy technologies. An article in "Nature Reviews Methods Primer" now provides a guide to freeze-casting methods that includes an overview on current and future applications and highlights characterization techniques with a focus on X-ray tomoscopy.
