Excellent job: Michelle Browne was recently honoured with two awards: the Curios Mind Award from Manager Magazine and 3rd place in the Academic Young Talent Award. The lively Irishwoman is working hard towards her dream of producing inexpensive green hydrogen. Michael O. R. Kröher from Manager Magazin portrays the HZB researcher in the cover story of lichtblick.
The green reconstruction of Ukraine: As a candidate for EU accession, Ukraine must initiate a series of reforms and develop a reconstruction plan, all in the midst of the Russian war of aggression. A German-Ukrainian-Polish project aims to help make Ukraine's climate and energy policy fit for EU accession.
There is a lot to do: HZB's first detailed greenhouse gas balance sheet is now available. Climate and Energy Manager Carina Hanke explains in an interview which are the biggest CO2 emitters and what we need to do now to achieve our goal of becoming greenhouse gas neutral by 2035.
Many construction sites: a lot of building work will start in 2024, especially at the Adlershof site. The construction department provides a brief insight into new building projects.
Here’s to good collaboration: How can we work well together at HZB and advance our work culture? The Diversity Officers invited people to discuss these questions. Many employees contributed great ideas.
"We still have to keep banging away at it" This is what our new Equal Opportunities Officer says in an interview. " A lot of people shut their eyes and act as though everything’s just fine. Equality has not been achieved yet, despite all our efforts."
We hope you enjoy reading the latest lichtblick issue!
As always, we are very happy to receive topics, suggestions, and feedback!
- Nanosilver as an electrocatalyst for CO₂ reductionVia electrolysis, CO2 can be reduced to CO, a raw material for further chemical products such as fuels. Within the GreenQuest Project, an internation team led by HZB chemist Prashanth Menezes has now systematically investigated catalyst layers made of silver nanoparticles, varying both the size of the particles and their density. The best yield was achieved with nanoparticles with diameters of around 10 nm, which were loosely distributed. Furthermore, they demonstrated how the economic efficiency of the electrochemical cell can be enhanced by integrating an additional chemical reaction at the anode, enabling the simultaneous production of a valuable formic acid, hydrogen, and CO in one device.
- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
- Discover HZB at our Open Day on 28 AugustWe warmly invite you to our Open Day at the Lise Meitner Campus of the Helmholtz Centre Berlin (HZB) in Wannsee! A varied programme awaits you, featuring around 20 stations, guided tours, talks and hands-on activities for all.
