The Radio TEDDY experimental show with the HZB - tune in on Saturdays at 2.40... The Helmholtz-Zentrum Berlin and Radio TEDDY continue their successful cooperation. In the next round, we will provide ideas for six exciting experiments that the Radio TEDDY moderator Leo will conduct for the children in front of the radio.
Accelerator physics: Experiment reveals new options for synchrotron light... Using this method, specialised synchrotron radiation sources would potentially be able to fill a gap in the arsenal of available light sources and offer a prototype for industrial applications. The work was published in Nature.
Perovskite/silicon tandem solar cells on the threshold of 30% efficiency The tandem cell provided stable performance for 300 hours – even without encapsulation. To accomplish this, the group headed by Prof. Steve Albrecht investigated physical processes at the interfaces to improve the transport of the charge carriers.
Future Information Technologies: Germanium telluride's hidden properties at the... Germanium Telluride is an interesting candidate material for spintronic devices. At BESSY II, a Helmholtz-RSF Joint Research Group has revealed how the spin texture switches by ferroelectric polarization within individual nanodomains.
Order in the disorder: density fluctuations in amorphous silicon discovered Such a-Si:H thin films have been used for decades in solar cells, TFT displays, and detectors. The results show that three different phases form within the amorphous matrix, which influences the quality and lifetime of the semiconductor layer.
Best electrolyser/photovoltaics combinations demonstrated in test fields One of the most promising ways to increase the availability of solar energy is to convert excess production into hydrogen. The PECSYS project has investigated the best possible material and technology combinations to facilitate such an operation.
Hope for better batteries – researchers follow the charging and discharging of... The use of silicon in batteries promises to increase their capacity. At the HZB, charging and discharging was observed live for the first time and insights were gained into how the material can be used even more advantageously.
Seminar für Architekt*innen Bauwerkintegrierte Photovoltaik: Architektur –... Im September veranstaltet die Beratungsstelle für BIPV „BAIP“ zusammen mit der Architektenkammer Niedersachsen ein Seminar für Architekt*innen zum Thema Bauwerkintegrierte Photovoltaik: Architektur-Gestaltung und Ausführung
Robust high-performance data storage through magnetic anisotropy An international team led by Prof. Dr. Matias Bargheer has now observed experimentally for the first time how a special spin-lattice interaction in these iron-platinum thin films cancels out the thermal expansion of the crystal lattice.
Optimize opto-electronic devices with new compact measuring system In order to develop efficient opto-electronic devices such as solar cells or LEDs, it is crucial to improve the quality of the semiconductors. To achieve this, it is necessary to determine the luminescence yield of the semiconductor material. For this ...
User research at BESSY II: Formation of a 2D meta-stable oxide in reactive... A research team from the Max Planck Institute for Chemical Energy Conversion has now described an important phenomenon that can occur when metal alloys are exposed to reactive environments at the synchrotron source BESSY II.
BESSY II: Experiment shows for the first time in detail how electrolytes become... For the first time an experiment was developed at BESSY II that shows how electrolytes become metallic. The transition to the state is shown by a change of colour from blue to gold. The publication even appears on the front page of SCIENCE Magazine.
