Success through high throughput
Perovskites are the great hope for further increasing the efficiency of solar modules in the future. Until now, their short service life has been considered the biggest hurdle to their practical use, but this could soon change. In the current issue of the journal Nature Energy, researchers from ...
Particles with pompom-like structure
The predictions of researchers that certain particles of matter with sufficiently high density would form a new state - crystalline and flowing at the same time - could be confirmed in the laboratory. More than 20 years ago, researchers predicted that with sufficiently high density certain ...
Important step towards opening up the third dimension for molecular fabrication
Three years ago, a group of physicists from Jülich successfully manipulated a single flat molecule into an upright, standing position. Their findings were published at the time in Nature. After months of experiments, they have now managed to knock the molecule back down again. The insights gained ...
“These types of structures inside magnetic solids suggest unique electrical and magnetic properties"
A team of scientists from Germany, Sweden and China has discovered a new physical phenomenon: complex braided structures made of tiny magnetic vortices known as skyrmions. Skyrmions were first detected experimentally a little over a decade ago and have since been the subject of numerous studies, ...
"Adiabatic cooling is a real quantum leap for scanning tunneling microscopy"
Scanning tunnelling microscopes capture images of materials with atomic precision and can be used to manipulate individual molecules or atoms. Researchers have been using the instruments for many years to explore the world of nanoscopic phenomena. A new approach by physicists at Forschungszentrum ...
Switching between different wavelengths
Jülich researchers, together with Italian and German colleagues, have developed a particularly cost-effective infrared detector that can be easily integrated into existing camera chips and smartphones. The new sensor can make two technically important ranges of infrared radiation visible, which ...
The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these contribute to the formation of aerosol particles as a precursor of raindrops and therefore impact the growth of clouds and pH of rainwater. In previous atmospheric ...
Nanostructured material and a new cell design pave the way for the production of silicon solar cells with more than 26 percent efficiency
There is no cheaper way to generate electricity today than with the sun. Power plants are currently being built in sunny locations that will supply solar electricity for less than two cents per kilowatt hour. Solar cells available on the market based on crystalline silicon make this possible with ...
"We believe that our findings represent a crucial breakthrough towards the goal of tracing electrons through chemical reactions in space and time"
In textbooks and explanatory videos, they are often depicted as colourful balloons or clouds: electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, it is not only ...
A key to producing green hydrogen more efficiently
A layer as thin as a single atom makes a huge difference: On the surface of an electrode, it doubles the amount of water split in an electrolysis system without increasing the energy requirements. Thus, the ultrathin layer also doubles the amount of hydrogen produced without increasing costs. ...
