Headline: Tandem solar cells with perovskite: Nanostructures help in many ways
■ Release Date: 2022.10.24
■ Published by: Helmholtz-Zentrum Berlin für Materialien und Energie
■ Keywords: perovskite, silicon, solar cell
■ Abstract:
By the end of 2021, scientists had presented perovskite silicon tandem solar cells with an efficiency close to 30 percent. This value was a world record for eight months, a long time for this hotly contested field of research. Scientists now describe how they achieved this record value with nanooptical structuring and reflective coatings.

Headline: How Imperfections can actually improve alloys
■ Release Date: 2022.10.26
■ Published by: University of Pittsburgh
■ Keywords: alloy, metal, metastable
■ Abstract:
Sometimes, in creating an alloy out of multiple metals, defects and structural instability can occur in the material. Now, researchers are harnessing those imperfections to make the material stronger while retaining its flexibility.
Headline: Limits of lithium extraction from thermal water
■ Release Date: 2022.10.26
■ Published by: Karlsruher Institut für Technologie (KIT)
■ Keywords: lithium, geothermal energy, battery
■ Abstract:
Pumping up thermal water, separating lithium, and using it to produce batteries for electric mobility -- the idea of lithium as an environmentally compatible and regionally available by-product of geothermal energy plants appears highly promising. However, it has not been clear so far whether domestic lithium extraction is really worthwhile. A team of researchers has now summarized the state of the art, analyzed raw materials markets, and assessed technologies.
Headline: Building with nanoparticles, from the bottom up
■ Release Date: 2022.10.26
■ Published by: Massachusetts Institute of Technology
■ Keywords: nanoparticles, sensors, silicon
■ Abstract:
Researchers created a technique for precisely arranging nanoparticles onto surfaces in arrays with arbitrary shapes that does not cause damage to the material's surface. The scalable technique could help make higher-performance devices like lasers, LEDs, sensors, and actuators.
Headline: Batteries without critical raw materials
■ Release Date: 2022.10.27
■ Published by: Helmholtz-Zentrum Berlin für Materialien und Energie
■ Keywords: sodium-ion battery, electrolyte, electrode
■ Abstract:
The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative. Researchers have investigated new combinations of electrolyte solutions and electrode materials for this purpose.
Headline: New era of two-dimensional ferroelectrics
■ Release Date: 2022.10.27
■ Published by: ARC Centre of Excellence in Future Low-Energy Electronics Technologies
■ Keywords: nanoelectronics, optoelectronics, ferroelectrics
■ Abstract:
A research team reviews the emerging field of 2D ferroelectric materials with layered van-der-Waals crystal structures, a novel class of materials that is highly interesting for future nanoelectronics, ultra-low energy electronics, high-performance, non-volatile data-storage, high-response optoelectronics, and flexible (energy-harvesting or wearable) electronics.
Headline: 'Kagome' metallic crystal adds new spin to electronics
■ Release Date: 2022.10.27
■ Published by: City University of Hong Kong
■ Keywords: vanadium, tin, microelectronic
■ Abstract:
Researchers have found that a novel metallic crystal displays unusual electronic behavior on its surface, thanks to the crystal's unique atomic structure. Their findings open up the possibility of using this material to develop faster and smaller microelectronic devices.
