Virtual tours: Experience the HZB in 360 degrees!
Unfortunately, due to Corona, we are currently unable to receive groups of visitors at HZB and guide them through our centre. Despite Corona, we would like to provide you with insights into HZB. Simply follow our 360-degree tours and experience how we conduct research at the BESSY II accelerator. Further tours are being planned.
"Make yourself comfortable and start your own virtual tour through our world of research! We invite you to move through the 360-degree worlds and pause at one station or another to discover something new," says Sandra Fischer from the Communications Department. She designed and realised the tours together with an external partner.
The first tour is through the BESSY II accelerator facility. Further tours, also at the Wannsee site, are being planned. "With this offer, we want to remain open to interested people even in times of a pandemic and arouse curiosity about the world of science."
Tour through the BESSY II accelerator: Follow the path of light
Have you always wanted to walk through an accelerator? The tours "The Path of Light" and "The Experiment" both start in the heart of BESSY II, the control room. Go to the place where electrons race through and emit light at almost the speed of light - the storage ring tunnel. There you will see the effort that has to be made to generate the coveted light. You can experience all the things we can explore with this light in the tour "The Experiment".
Here you get to the tour. We hope you enjoy it!
Note for our cooperation partners at BESSY II:
360-degree views ("spherical panoramas") of various beamlines are available in the media library. You are welcome to use these to explain your work at BESSY II (e.g. in lectures or for groups of visitors). If you have any questions, please contact Sandra Fischer.
Perovskite solar cells from the slot die coater - a step towards industrial production
Solar 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 determined
MXenes 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.
Electrocatalysis under the atomic force microscope
A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometre-fine structures as well as the electric current and the frictional force at solid-liquid interfaces. A team from the Helmholtz-Zentrum Berlin (HZB) and the Fritz Haber Institute (FHI) of the Max Planck Society has succeeded in analysing electrocatalytically active materials and gaining insights that will help optimise catalysts. The method is also potentially suitable for studying processes on battery electrodes, in photocatalysis or on active biomaterials.
