Solar Cell Contacts From Tubes

Innovative Fine Line Metallization Technology Promises Higher Efficiency Values

20-10-2014

Together with industrial partners Merck, Heraeus and ASYS, researchers from the Fraunhofer Institute for Solar Energy Systems ISE have developed innovative new materials and contactless techniques for applying ultrafine, homogeneous contact fingers to solar cells. This ‘dispensing’ technology can ...

Physicists render usable method for detecting extremely rare inert gas isotopes for water dating

17-10-2014

In the earth and environmental sciences, radioactive isotopes, atom variants that decay over time, play a major role in age determination. A radioactive isotope of the inert gas argon (39Ar), for example, is used to determine the age of water or ice. Such isotopes are extremely rare, however – ...

Artificially More Efficient Than Naturally: Researchers Succeed in Creating Artificial Photosynthesis

14-10-2014

As one of the most important chemical processes on earth, photosynthesis makes it possible to directly store the sun’s energy. Until now, only plants and some other organisms have been able to photosynthesize. Now researchers at the Johannes Kepler University (JKU) Linz have also artificially ...

How ceramics get super-tough

Scientists find new toughening mechanism

13-10-2014

Researchers have identified a previously unknown mechanism that makes a rare kind of ceramics super-tough. The findings may show a way to compose super-hard and super-tough ceramics for industrial application, as the team around DESY scientist Dr. Nori Nishiyama reports in the journal Scientific ...

A quick look at electron-boson coupling

Berkeley Lab researchers use ultrafast spectroscopy on many body effects

10-10-2014

Imagine being able to tune the properties of a solid material just by flashing pulses of light on it, for example turning an insulator into a superconductor. That is just one potential payoff down-the-road from the physical phenomenon of electrons and atoms interacting with ultrashort pulses of ...

Cloud towers above the Amazon

09-10-2014

"Please buckle up. We are flying through an area with strong turbulence.” Some passengers might be petrified by such an announcement, but the atmosphere and climate researchers from Germany, Brazil and Israel were delighted last month to hear these words. Within the framework of a large-scale ...
