After a careful assessment of the situation, the management decided that operations at HZB would be resumed step by step from 4 May onwards. Strict security regulations apply. BESSY II will be available again for in-house research from 11 May. For Sars-CoV-2-relevant measurements a fast access to BESSY II has been established.
We will continuously update the information on this page. We follow the current recommendations of the Robert Koch Institute, the Federal Ministry of Health and the Senate Chancellery and ask all parties involved for their understanding.
Gradual resumption of operations at HZB
The HZB gradually resumes operations - under permanent observation of the situation and strict security regulations.
The BESSY II accelerator will be put back into operation, but will initially only be available to HZB researchers. In the next few weeks, the laboratories will again be able to operate in a restricted manner, in accordance with safety regulations. Please contact the laboratory managers for further details.
User operation at BESSY II will be suspended until 31 May 2020. Exception: Sars-CoV-2 relevant measurements on the MX-Beamlines can be performed. For research groups we have established a fast-track access.
The patient operation in the proton therapy takes place according to plan. Should changes become necessary due to developments, all those affected will be informed.
Furthermore these measures apply:
Immediate cancellation of all events and visitor groups until 20.07.2020 in accordance with the notification of the Senate Chancellery, e.g.:
- The Long Night of Science on 6 June 2020
- Physics for breakfast on 8 July 2020 is cancelled.
- Groups of visitors cannot visit our facilities.
- School lab groups are cancelled.
- Workshops and scientific events are cancelled.
- all trainings offered by HZB company sports are cancelled.
Access for external companies: In order to ensure effective containment of the corona virus, employees of external companies may only enter HZB if they have had no contact with an infected person within the last three weeks (neither privately nor professionally). This must be confirmed in a written form (see download box). Further information can be obtained from your respective contact person at HZB.
HZB staff will get fresh information via the intranet.
- Perovskite solar cells from the slot die coater - a step towards industrial productionSolar cells made from metal halide perovskites achieve high efficiencies and their production from liquid inks requires only a small amount of energy. A team led by Prof. Dr. Eva Unger at Helmholtz-Zentrum Berlin is investigating the production process. At the X-ray source BESSY II, the group has analyzed the optimal composition of precursor inks for the production of high-quality FAPbI3 perovskite thin films by slot-die coating. The solar cells produced with these inks were tested under real life conditions in the field for a year and scaled up to mini-module size.
- Superstore MXene: New proton hydration structure determinedMXenes are able to store large amounts of electrical energy like batteries and to charge and discharge rather quickly like a supercapacitor. They combine both talents and thus are a very interesting class of materials for energy storage. The material is structured like a kind of puff pastry, with the MXene layers separated by thin water films. A team at HZB has now investigated how protons migrate in the water films confined between the layers of the material and enable charge transport. Their results have been published in the renowned journal Nature Communications and may accelerate the optimisation of these kinds of energy storage materials.
- TU Berlin appoints Renske van der Veen as professorFor the past two years, Dr Renske van der Veen has led a research group in time-resolved X-ray spectroscopy and electron microscopy at HZB. Her research focuses on catalytic processes that enable, for example, the production of green hydrogen. She has now been appointed to a S-W2 professorship at the Institute of Optics and Atomic Physics (IOAP) at the Technische Universität Berlin.
