- Nanoparticles in lithium-sulphur batteries detected with neutron experiment
An HZB team has for the first time precisely analysed how nanoparticles of lithium sulphide and sulphur precipitate onto battery electrodes during the course of the charging cycle. The results can ... - Radiography and Tomography of Egyptian Papyri
Researchers from the Egyptian Museum and Papyrus Collection, Berlin universities and Helmholtz-Zentrum Berlin studied a small piece of papyrus that was excavated on the island of Elephantine on the... - Development of a miniaturised EPR spectrometer
Several research institutions are developing a miniaturized electron paramagnetic resonance (EPR) device with industrial partner Bruker to investigate semiconductor materials, solar cells, catalyst... - Copper oxide photocathodes: laser experiment reveals location of efficiency loss
Solar cells and photocathodes made of copper oxide might in theory attain high efficiencies for solar energy conversion. In practice, however, large losses occur. Now a team at the HZB has been abl... - "Molecular scissors" against plastic waste
A research team from the University of Greifswald and Helmholtz-Zentrum-Berlin (HZB) has solved the molecular structure of the important enzyme MHETase at BESSY II. MHETase was discovered in bacter... - Catalyst research for solar fuels: Amorphous molybdenum sulphide works best
Efficient and inexpensive catalysts will be required for production of hydrogen from sunlight. Molybdenum sulphides are considered good candidates. A team at HZB has now explained what processes ta... - X-ray analysis of carbon nanostructures helps material design
Nanostructures made of carbon are extremely versatile: they can absorb ions in batteries and supercapacitors, store gases, and desalinate water. How well they cope with the task at hand depends lar... - Water is more homogeneous than expected
In order to explain the known anomalies in water, some researchers assume that water consists of a mixture of two phases even under ambient conditions. However, new X-ray spectroscopic analyses at ... - How could artificial photosynthesis contribute to limiting global warming?
If CO2 emissions do not fall fast enough, then CO2 will have to be removed from the atmosphere in the future to limit global warming. Not only could planting new forests and biomass contribute to t... - Milestone for bERLinPro: photocathodes with high quantum efficiency
A team at the HZB has improved the manufacturing process of photocathodes and can now provide photocathodes with high quantum efficiency for bERLinPro. Teams from the accelerator physics and the...
- 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 ... - 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... - 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... - 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 ... - 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... - 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... - 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.... - 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... - 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 catalysis through novel study of X-ray absorption spectroscopy
