Highly Efficient Solar Cells Thanks to Solid Foundation

July 17, 2019

The sun is an inexhaustible and sustainable source of energy. Hence, photovoltaics is gaining importance in German energy production. Among promising materials for solar cells – with a high efficiency and low production costs – are metal-organic Perovskites. Researchers of Karlsruhe Institute of Technology (KIT) have developed a novel type of highly efficient nickel oxide hole transport layer that can be deposited on large areas and reaches record efficiencies in these solar cells.

Technologies for the Sixth Generation Cellular Network

July 16, 2019

Future wireless data networks will have to reach higher transmission rates and shorter delays, while supplying an increasing number of end devices. For this purpose, network structures consisting of many small radio cells will be required. To connect these cells, high-performance transmission lines at high frequencies up to the terahertz range will be needed. Moreover, seamless connection to glass fiber networks must be ensured, if possible. Researchers of Karlsruhe Institute of Technology (KIT) use ultra-rapid electro-optical modulators to convert terahertz data signals into optical signals. This is reported in Nature Photonics (DOI: 10.1038/s41566-019-0475-6).

Producing Graphene from Carbon Dioxide

July 08, 2019

The general public knows the chemical compound of carbon dioxide as a greenhouse gas in the atmosphere and because of its global-warming effect. However, carbon dioxide can also be a useful raw material for chemical reactions. A working group at Karlsruhe Institute of Technology (KIT) has now reported on this unusual application in the ChemSusChem journal. They are using carbon dioxide as a raw material to produce graphene, a technological material which is currently the subject of intense study. (DOI: 10.1002/cssc.201901404)

Granular Aluminum for Future Computers

May 02, 2019

Computers based on quantum mechanical principles can solve certain tasks particularly efficiently. Their information carriers, the so-called qubits, not only have the values "0" and "1", but also states in between, called superposition states. However, maintaining such a state is difficult. Scientists at the Karlsruhe Institute of Technology (KIT) have now used granular aluminum (nicknamed grAl) for qubits and have shown that this superconducting material has great potential to overcome the previous limits of quantum hardware. The researchers report in the journal Nature Materials (DOI: 10.1038 / s41563-019-0350-3).
