- New sample holder for protein crystallography
An HZB research team has developed a novel sample holder that considerably facilitates the preparation of protein crystals for structural analysis. A short video by the team shows how proteins in s... - Dynamic pattern of Skyrmions observed
Tiny magnetic vortices known as skyrmions form in certain magnetic materials, such as Cu2OSeO3. These skyrmions can be controlled by low-level electrical currents - which could facilitate more ener...
- New insights into high-temperature superconductors
After 30 years of research, there are still many unsolved puzzles about high-temperature superconductors - among them is the magnetic "stripe order" found in some cuprate superconductors. A Danish ... - Nanostructuring increases efficiency of metal-free photocatalysts by factor eleven
Polymeric carbon nitrides exhibit a catalytic effect in sunlight that can be used for the production of hydrogen from solar energy. However, the efficiency of these metal-free catalysts is extremel... - Kesterite solar cells: better opto-electronic properties
Specific changes in the composition of kesterite-type semiconductors make it possible to improve their suitability as absorber layers in solar cells. As a team at the Helmholtz-Zentrum Berlin showe... - Insight into catalysis through novel study of X-ray absorption spectroscopy
An international team has made a breakthrough at BESSY II. For the first time, they succeeded in investigating electronic states of a transition metal in detail and drawing reliable conclusions on ... - World record: Fastest 3D tomographic images at BESSY II
An HZB team has developed an ingenious precision rotary table at the EDDI beamline at BESSY II and combined it with particularly fast optics. This enabled them to document the formation of pores in... - Insight into loss processes in perovskite solar cells enables efficiency improvements
In perovskite solar cells, charge carriers are mainly lost through recombination occurring at interface defect sites. In contrast, recombination at defect sites within the perovskite layer does not... - Nanoscale heat transport under the microscope
A team of researchers from the Helmholtz-Zentrum Berlin (HZB) and the University of Potsdam has investigated heat transport in a model system comprising nanometre-thin metallic and magnetic layers.... - Patented nanostructure for solar cells: Rough optics, smooth surface
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A t... - Hanwha Q-Cells Quantsol Awards 2018
Six young researchers received a Hanwha Q-Cells Quantsol Award for their self-developed Photovoltaics. This award is presented by the organizers of the international summer school Quantsol together... - Boost the efficiency of silicon solar cells
The efficiency of a solar cell is one of its most important parameters. It indicates what percentage of the solar energy radiated into the cell is converted into electrical energy. The theoretical ... - Existence of blue phosphorus proved
Until recently, the existence of "blue" phosphorus was pure theory: Now an HZB team was able to examine samples of blue phosphorus at BESSY II for the first time and confirm via mapping of their el... - Novel X-ray microscope to produce microstructural images in situ and in vivo
An interdisciplinary team of scientists will develop a new imaging method to investigate osteoporosis and other bone diseases in living subjects. Prof. Silke Christiansen, a scientist at HZB and ph... - Why certain compounds have the potential to convert light into electrical energy
Transition-metal complexes - that is a cumbersome word for a class of molecules with important properties: An element from the group of transition metals sits in the centre. The outer electrons of ...
- Nanodiamonds as energy materials: tuning the functionalities
An international team has shed light onto interactions between nanodiamonds and water molecules. Experiments at synchrotron sources showed how hydrogenated groups on nanodiamond surfaces change the... - Better cathode materials for Lithium-Sulphur-Batteries
