There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

Photovoltaics (PV) is one of the key technologies of a sustainable energy supply based on renewable energy. Besides silicon-based photovoltaics, which presently dominates the market, there are other materials, such as perovskite, that also show great potential. Scientists are testing the proof of concept of these new types of solar cells.

Hydrogen peroxide, ethene, alcohols: The Fraunhofer lighthouse project “Electricity as a raw material” is developing electrochemical processes that use renewable electricity to synthesize basic chemicals - with the aim of making the chemical industry more sustainable. From June 11 to 15, Fraunhofer UM-SICHT will be presenting the results together with eight other Fraunhofer Institutes at ACHEMA 2018.

So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics. Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a quantum simulator.
