Short description
The Helmholtz Association contributes to solving major challenges facing society, science and industry with top scientific achievements in six research areas: Energy, Earth and Environment, Health, Key Technologies, Structure of Matter, Transport and Space. With 30,000 employees in 16 research centres and an annual budget of approximately 3 billion euros, the Helmholtz Association is Germany’s largest scientific organisation. Its work follows in the tradition of the great natural scientist Hermann von Helmholtz (1821-1894).
Molecules that self-assemble into monolayers for efficient perovskite solar cells
A team at the HZB has discovered a new method for producing efficient contact layers in perovskite solar cells. It is based on molecules that organise themselves into a monolayer. In recent years, solar cells based on metal halide perovskites have achieved an exceptional increase in efficie ... more
Antiferromagnetic dysprosium reveals magnetic switching with less energy
HZB scientists have identified a mechanism with which it may be possible to develop a form of magnetic storage that is faster and more energy-efficient. They compared how different forms of magnetic ordering in the rare-earth metal named dysprosium react to a short laser pulse. They discove ... more
Charge transport in hybrid silicon solar cells
The system they investigated is based on conventional n-type silicon wafers coated with the highly conductive polymer mixture PEDOT:PSS and displays a power conversion efficiency of about 14%. This combination of materials is currently extensively investigated by many teams in the research ... more
