Dear cfaed members: New round, new luck! Once again, the famous cfaed SIC is open for entries! We are looking for your inspiring images 'from the lab': the most beautiful scientific illustration, SEM-Image, photo or graphic – feel free to be creative and illustrate your work in your way – or take a snapshot of your amazing science! The prizes for the best 3 submissions are: a Standsome high-desk positioner …and a large-size printed version on aluminum of your picture.
A selection of the submitted images will be used in our official PR-materials. In addition, there is also the chance that the most beautiful images will be displayed in the cfaed building (BAR) and in an exhibition that will take place in fall in the ALTANA Galerie, which is TUD's art exhibition space.
See more info about how to participate and a selection of 2020 entries

Congratulations to Senorics! The high-tech spin-off company from TUD has reached the next big milestone on its way to the mass market. By receiving 2 million EUR funding through KET’s pilot line program (Key Enabling Technologies) from the Saxon government, Senorics will be able to scale their material sensing technology towards multi million quantities. This will allow them to integrate their technology into consumer devices, enabling everyone to experience the positive impact of material sensing.cfaed supported Senorics co-founder and CTO Dr. Robert Brückner in the PhD-phase.

The advantageous properties of metal halide perovskites include their high light-harvesting capacity and their remarkable ability to efficiently convert solar energy into electrical energy. Another special feature of these materials is that both charge carriers and ions are mobile within them. While charge carrier transport is a fundamental process required for the photovoltaic operation of the solar cell, ionic defects and ion transport often have undesirable consequences on the performance of these devices. Despite significant progress in this field of research, many questions regarding the physics of ions in perovskite materials remain open.
On the way to a better understanding of these structures, the Technical Universities of Chemnitz and Dresden have now taken a big step forward. In a joint investigation by the research groups around Prof. Dr. Yana Vaynzof (Chair of Emerging Electronic Technologies at the Institute of Applied Physics and Center for Advancing Electronics Dresden – cfaed, TU Dresden) and Prof. Dr. Carsten Deibel (Optics and Photonics of Condensed Matter, Chemnitz University of Technology) under the leadership of Chemnitz University of Technology, the two teams uncovered the ionic defect landscape in metal halide perovskites. They were able to identify essential properties of the ions that make up these materials. The migration of the ions leads to the presence of defects in the material, which have a negative effect on the efficiency and stability of perovskite solar cells. The working groups found that the motion of all observed ions, despite their different properties (such as positive or negative charge), follows a common transport mechanism and also allows the assignment of defects and ions. This is known as the Meyer-Neldel rule. The results were published in the renowned journal "Nature Communications" (11, 6098 (2020)) (https://www.nature.com/articles/s41467-020-19769-8).

Joint research work between Chemnitz University of Technology and Technische Universität Dresden under Chemnitz leadership reveals ionic defect landscape in metal halide perovskites - publication in renowned journal Nature Communications
The group of so-called metal halide perovskites as materials has revolutionized the field of photovoltaics in recent years. Generally speaking, metal halide perovskites are crystalline materials that follow the structure ABX3, with varying composition. Here, A, B, and X can represent a combination of different organic and inorganic ions. These materials have a number of properties that are ideal for use in solar cells and could help to make optoelectronic devices such as lasers, light-emitting diodes (LEDs), or photodetectors much more efficient. With regard to the development of a resource- and energy-efficient technology, the relevance of research on these materials is very high.

"The project is an important step for the further development of our university. Prof. Feng's research group on Molecular Functional Materials and Prof. Ruck's group from the Cluster of Excellence ct.qmat will find optimal conditions for their excellent work here", explains the Rector of TU Dresden, Prof. Ursula M. Staudinger. "The fact that they are moving into a new home together also offers opportunities for even stronger interdisciplinary cooperation in the future," she adds.
The TU Dresden has started construction work for a new office and laboratory building on Stadtgutstraße, close to the campus. For the first time, the university is also taking over the construction management under its own direction. By August next year, 1,200 square meters of office and lab space will be built. The Chair for Molecular Functional Materials, which is integrated in the Center for Advancing Electronics Dresden (cfaed), as well as the Cluster of Excellence Complexity and Topology in Quantum Matter (ct.qmat) will move in.
