Bernd Rech boardmember of the "work group of energy"
Bernd Rech will focus on renewable energy issues.
Prof. Bernd Rech will speak on recent findings in thin film silicon photovoltaik research at the autumn meeting of the energy work group of the Deutsche Physikalische Gesellschaft. Rech had been elected into the board of the work group earlier this year.
Main topic will be polycrystalline silicon thin films on glas. HZB researchers were able to increase the efficiency of these solar cells considerably
As speaker of the renewable energy program of the Helmholtz Association, Bernd Rech intends to discuss issues of the turnaround in energy policy in his new role in the DPG.
The autumn meeting of the DPG energy work group wil be in Bad Honnef on October 1 and 2. The Deutsche Physikalische Gesellschaft is an organisation that has as its member scientists working in universities, research institutions, and the industry as well as teachers and (PhD-)students. There are also about 160 institutional members.
- Lithium-sulphur pouch cells investigated at BESSY IIA team from HZB and the Fraunhofer Institute for Material and Beam Technology (IWS) in Dresden has gained new insights into lithium-sulphur pouch cells at the BAMline of BESSY II. Supplemented by analyses in the HZB imaging laboratory and further measurements, a new picture emerges of processes that limit the performance and lifespan of this industrially relevant battery type. The study has been published in the prestigious journal Advanced Energy Materials.
- Two Humboldt-Fellows join HZBIn 2024, two young scientists joined HZB as Humboldt Fellows. Kazuki Morita joined Prof. Antonio Abate's group and brings his expertise in modelling and data analysis to solar energy research. Qingping Wu is an expert in battery research and works with Prof. Yan Lu on high energy density lithium metal batteries.
- Less is more: Why an economical Iridium catalyst works so wellIridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the Iridium, is as efficient and stable over time as the best commercial catalyst. Measurements at BESSY II have now revealed how the special chemical environment in the P2X catalyst during electrolysis promotes the oxygen evolution reaction during water splitting.
