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.

Finding Order in Chaos: Scientists Determine the Structure of Glass-shaping Protein in Sponges

Published on Wed, 25 Nov 2020 in PRESS RELEASES

Sponges are some of the oldest animals on Earth. They live in a wide range of waters, from lakes to deep oceans. Remarkably, the skeleton of some sponges is built out of a network of highly symmetrical glass structures. These glass scaffolds have intrigued researchers for a long time. How do sponges manipulate disordered glass into the skeletal elements which are so regular? Researchers from B CUBE – Center for Molecular Bioengineering at TU Dresden together with the teams from the Center for Advancing Electronics Dresden (cfaed) / Dresden Center for Nanoanalysis (DCN) and the Swiss Light Source at the Paul Scherrer Institute in Switzerland are the first to determine the three dimensional (3D) structure of a protein responsible for glass formation in sponges. They explain how the earliest and, in fact, the only known natural protein-mineral crystal is formed. The results were published in the journal “PNAS.”

Overpriced? TUD Researchers Explain Artificial Price Increases in the Taxi App Uber

Apps such as Uber are an important mobility feature in many big cities. Driving others from A to B in their own car has become a job for many people. However, many drivers complain that their income is too low. In May 2019, the US television station ABC reported how Uber drivers at Washington airport artificially inflated the price of the service by all going offline at the same time. Within a few minutes, the price of the service had risen by 13 dollars, which almost doubled the amount.
How exactly does this strategy work and when is it used? This is what Dr. Malte Schröder and Professor Marc Timme from the Chair for Network Dynamics at the Center for Advancing Electronics Dresden (cfaed) and the Institute for Theoretical Physics at TU Dresden have been investigating alongside PhD students David-Maximilian Storch and Philip Marszal.

Broad spectrum. Novel hybrid material proves an efficient photodetector

Press release from HZDR, 9 April, 2020

Digital cameras as well as many other electronic devices need light-sensitive sensors. In order to cater for the increasing demand for optoelectronic components of this kind, industry is searching for new semiconductor materials. They are not only supposed to cover a broad range of wavelengths but should also be inexpensive. A hybrid material, developed in Dresden, fulfills both these requirements. Himani Arora, a physics PhD student at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), demonstrated that this metal-organic framework can be used as a broadband photodetector. As it does not contain any cost-intensive raw materials, it can be produced inexpensively in bulk.
