HySPRINT Photovoltaics Lab inaugurated

After around four years of renovation, photovoltaics research groups moved into their offices in Kekuléstraße on 20 June 2024. With the reopening, the building has also been given a new name that makes the research more visible: it is now called HySPRINT Photovoltaics Lab.

The conversion had become necessary because the ventilation capacity was no longer sufficient for the laboratory activities. The newly installed ventilation system is so large that it is now located on the roof instead of in the building. The supporting structure is a technical platform that stands on 14 supports with a separate foundation virtually inside the building.

To build the stage, the rooms from the basement to the upper floor had to be emptied. The expandable ventilation system now enables the operation of the HySPRINT laboratories and the KOALA laboratory as well as the expansion of other modern laboratories in the building. The technical platform also provides the technical requirements for installing a photovoltaic system on the roof.

Eva Unger, Steve Albrecht and Antonio Abate hosted a barbecue at the opening and thanked all those who helped with the conversion of the building. In their short speeches, they also looked back on the history of the building. They honoured the research that took place in the former Institute for Silicon Photovoltaics and contributed significantly to the reputation of the HZB. A new era has long since begun with perovskite research and world records. In September 2023, the HZB teams won the first Helmholtz High Impact Award for their outstanding research on novel perovskite materials.

    Porous Radical Organic framework improves lithium-sulphur batteries
    A team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulphur batteries. The material is based on polymers that form a framework with open pores (known as radical-cationic covalent organic frameworks or COFs). Catalytically accelerated reactions take place in these pores, firmly trapping polysulphides, which would shorten the battery life. Some of the experimental analyses were conducted at the BAMline at BESSY II.

    Shedding light on insulators: how light pulses unfreeze electrons
    Metal oxides are abundant in nature and central to technologies such as photocatalysis and photovoltaics. Yet, many suffer from poor electrical conduction, caused by strong repulsion between electrons in neighboring metal atoms. Researchers at HZB and partner institutions have shown that light pulses can temporarily weaken these repulsive forces, lowering the energy required for electrons mobility, inducing a metal-like behavior. This discovery offers a new way to manipulate material properties with light, with high potential to more efficient light-based devices.
