Dr. rer. nat. Agnieszka Paszuk received the YOUNG SCIENTIST AWARD for the best poster presentation during the 18th European Workshop on Metal-Organic Vapour Phase Epitaxy (EW-MOVPE 18th) in Vilnius, Lithuania.
The aim of the workshop was to bring together scientists and engineers to discuss the latest achievements, trends and future challenges in MOVPE. The unique format of this workshop consisted of eight invited plenary lectures, four poster presentations and three short courses. The focus was on the discussions and exchange of scientific ideas during the poster sessions.
n the department of photovoltaics, a large-scale device is currently being put into operation with which photoluminescence measurements on half-size
for the solar energy conversion. Photoluminescence is a process in which a semiconductor emits light characteristic of its optoelectronic properties after illumination. The efficiency of this process is directly linked to the suitability of the material for solar energy conversion. The new measuring station is a so-called streak camera system, whose main components are a femtosecond laser and a streak camera. It will be possible to follow the temporal course of photoluminescence with high temporal resolution as well as spectral resolution. The measuring station represents a substantial extension of the experimental possibilities in the field of photovoltaics and will contribute decisively to the development of next generation semiconductor devices. The large-scale facility was funded by the EU and the DFG.
"Modular Architecture for Artificial Photosynthesis" is the title of a project of the TU Ilmenau, which was awarded a gold medal at the iENA inventors' fair".
A team of researchers from the Technical University of Ilmenau, the University of Cambridge and CALTECH received a gold medal at the Inventors' Fair for their invention to build a water-splitting cell. Connected it is again with records.
Artificial photosynthesis as a solution
How can the question of clean energy be answered?
The scientist Prof. Dr. Thomas Hannappel relies on hydrogen.
"Artificial photosynthesis uses an artificial leaf, so to speak, which directly produces hydrogen by splitting water.
The TU Ilmenau has made a spectacular breakthrough in the research of new regenerative energies from a scientific point of view. An international research team led by Prof. Thomas Hannappel increased the efficiency of so-called artificial photosynthesis from 12.4 to 14 percent. This result, published in the leading scientific journal Nature comminications, is an important step towards solving the world's energy problems.
The Technical University of Ilmenau has made a spectacular breakthrough in the research of new regenerative energies from a scientific point of view. An international research team led by Professor Thomas Hannappel from Ilmenau increased the efficiency of so-called direct solar water splitting from 12.4 to 14 percent. The method, which is based on artificial photosynthesis, allows the fuel hydrogen to be produced from the light of the sun - cleanly, sustainably and cost-effectively. The spectacular record result, published in the leading scientific journal "Nature Communications", could be the solution to the world's energy problems.
No less than tackling the solution to mankind's greatest problems is the claim of the department of photovoltaics. The team around Thomas Hannappel makes this a matter of watching.
Fraunhofer ISE, Soitec, CEA-Leti and our group, formerly at the Helmholtz-Zentrum Berlin für Materialien und Energie, have together set a new absolute world record for the conversion of solar energy directly into electrical energy. We used a stacked cell arrangement with four different sub-cells. The new record efficiency of 44.7% was measured under a concentration of 297 suns.
