New lichtblick is out: Read the digital magazine now
The energy transition presents us all with major challenges. We need not only electricity from renewable sources, but also storage solutions. At the Wannsee site, Yan Lu's team is researching novel lithium-sulphur batteries that can store much more energy than conventional batteries. The laboratory is unique in the Berlin-Brandenburg research landscape. In the cover story, the head of department tells us what motivates her about her work.
Rutger Schlatmann from the Photovoltaics Competence Centre PVcomB is also concerned with how the transformation of the energy system can succeed. Since autumn 2022, he has been chairman of the European advisory platform ETIP-PV and advises politicians on what framework conditions the solar industry needs in Europe. "The pressure to act is great," he admits in the interview.

- Postdocs at HZB: Crucial for research, innovation and diversityAt HZB, 117 postdocs from 29 countries are employed. They play a crucial role in driving the main research activities, fostering creativity and innovation. To honor them, the Postdoc Appreciation Week was first organised in the USA in 2009 and has in the meantime become a regular event in Germany as well in the third week of September every year.
- Green hydrogen: MXenes shows talent as catalyst for oxygen evolutionThe MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalised, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the best metal oxide catalysts currently available. The team is now extensively characterising these MXene catalysts for water splitting at the Berlin X-ray source BESSY II and Soleil Synchrotron in France.
- Green hydrogen: ‘Artificial leaf’ becomes better under pressureHydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team at HZB has now shown that the efficiency of PEC cells can be significantly increased under pressure.
