Climate change and its causes are undisputed. But how do we get from knowledge to action? What can science contribute to this? On Thursday, 5.12.2019 at 17:00 Clara Mayer (Fridays for Future), Volker Quaschning (HTW Berlin and Scientists for Future), Bernd Rech (scientific director of the HZB) and Kira Vinke (Potsdam Institute for Climate Impact Research) will discuss these questions. The event takes place in the Bunsen lecture hall of WISTA in Adlershof and is open to the public. Admission is free.
Countless scientific studies show how important it is to limit global warming. We must reduce greenhouse gas emissions at all levels of society and in all sectors in order to achieve our climate targets. But there are many hurdles to implementation. What can science do to speed up action here? Should science interfere at all?
These questions are discussed in an open debate. Participants are Clara Mayer from Fridays for Future, Prof. Volker Quaschning (HTW Berlin and Scientists for Future), Prof. Bernd Rech (Scientific Director of the HZB) and Dr. Kira Vinke of the Potsdam Institute for Climate Impact Research. The debate will be moderated by Rutger Schlatmann (Head of PVcomB at HZB).
The debate is open to the public and will take place in the Bunsen lecture hall of WISTA. Admission is free.
As the discussion takes place within the international user meeting at the HZB, the discussion language is English.
Venue: Bunsen Lecture Hall WISTA, Rudower Chaussee 17, 12489 Berlin
Time: Thursday, 5.12.2019 from 17:00 until 18:30
- Lithium-sulphur batteries with lean electrolyte: problem areas clarifiedUsing a non-destructive method, a team at HZB investigated practical lithium-sulphur pouch cells with lean electrolyte for the first time. With operando neutron tomography, they could visualise in real-time how the liquid electrolyte distributes and wets the electrodes across multilayers during charging and discharging. These findings offer valuable insights into the cell failure mechanisms and are helpful to design compact Li-S batteries with a high energy density in formats relevant to industrial applications.
- Self assembling monolayer can improve lead-free perovskite solar cells tooTin perovskite solar cells are not only non-toxic, but also potentially more stable than lead-containing perovskite solar cells. However, they are also significantly less efficient. Now, an international team has succeeded in reducing losses in the lower contact layer of tin perovskite solar cells: The scienstists identified chemical compounds that self-assemble into a molecular layer that fits very well with the lattice structure of tin perovskites. On this monolayer, tin perovskite with excellent optoelectronic quality can be grown, which increases the performance of the solar cell.
- Berlin Science Award goes to Philipp AdelhelmBattery researcher Prof. Dr. Philipp Adelhelm has been awarded the 2024 Berlin Science Award. He is a professor at the Institute of Chemistry at Humboldt University in Berlin (HU) and heads a joint research group at HU and the Helmholtz Zentrum Berlin (HZB). The materials scientist and electrochemist is investigating sustainable batteries, which play a key role in the success of the energy transition. He is one of the leading international experts in the field of sodium-ion batteries.
