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.
- Tomography shows high potential of copper sulphide solid-state batteriesSolid-state batteries enable even higher energy densities than lithium-ion batteries with high safety. A team led by Prof. Philipp Adelhelm and Dr. Ingo Manke succeeded in observing a solid-state battery during charging and discharging and creating high-resolution 3D images. This showed that cracking can be effectively reduced through higher pressure.
- European pilot line for innovative photovoltaic technology based on tandem solar cellsPEPPERONI, a four-year Research and Innovation project co-funded under Horizon Europe and jointly coordinated by Helmholtz-Zentrum Berlin and Qcells, will support Europe in reaching its renewable energy target of climate neutrality by 2050. The project will help advance perovskite/silicon tandem photovoltaics (PV) technology’s journey towards market introduction and mass manufacturing.
- How photoelectrodes change in contact with waterPhotoelectrodes based on BiVO4 are considered top candidates for solar hydrogen production. But what exactly happens when they come into contact with water molecules? A study in the Journal of the American Chemical Society has now partially answered this crucial question: Excess electrons from dopants or defects aid the dissociation of water which in turn stabilizes so-called polarons at the surface. This is shown by data from experiments conducted at the Advanced Light Source at Lawrence Berkeley National Laboratory. These insights might foster a knowledge-based design of better photoanodes for green hydrogen production.
