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!
- A simpler way to inorganic perovskite solar cellsInorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.
- BESSY II: How pulsed charging enhances the service time of batteriesAn improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.
- Fuel Cells: Oxidation processes of phosphoric acid revealed by tender X-raysThe interactions between phosphoric acid and the platinum catalyst in high-temperature PEM fuel cells are more complex than previously assumed. Experiments at BESSY II with tender X-rays have decoded the multiple oxidation processes at the platinum-electrolyte interface. The results indicate that variations in humidity can influence some of these processes in order to increase the lifetime and efficiency of fuel cells.
