End of March, a delegation from the Czech Republic visited HZB at the Wannsee campus. The programme included a visit to the apprentices’ workshop and exchanges regarding opportunities for apprenticeships and upskilling at HZB.
On 30 March, the conference room in Wannsee was well attended; with guests from the Czech Republic and many colleagues from HZB who joined as contact persons.
It was a great pleasure to welcome the delegation of 30 people from apprenticeship schools and training institutes from the Czech Republic during their stay in Berlin and Dresden. This two-day information trip was organised by the German-Czech Chamber of Industry and Commerce on behalf of the German Federal Ministry for Economic Affairs and Climate Action (BMWK) and professionally accompanied by iMoVE (international Marketing of Vocational Education), a working area of the Federal Institute for Vocational Education and Training (BIBB).
Getting to know the HZB: research, institution and exchange
The programme in Wannsee included an introduction to the major research topics at HZB and its profile as an employer. Beyond the facts and figures, the focus here was on HZB's commitment to diversity, sustainability, and the comprehensive support of its employees. In another part, Christina Herold, responsible for apprenticeships at HZB, presented the various training opportunities at the centre (more on this below).
In the second part of the programme, the guests either experienced a guided tour of the apprentice workshop for fine-precision mechanics, organized by Christian Remus or gained impressions of the research area Quantum Phenomena in New Materials, thanks to a guided tour by Karel Prokes in Czech. The guests enjoyed these concrete presentations, asked questions and got many inputs. Special thanks go to the trainers Manuela Eckert, Christian Remus, Katja Wiggert and Nicholas Coon, the trainees Matthias Skubida and Felix Ludwig as well as the Czech colleague Karel Prokes, who ensured a lively and informative exchange.
The HZB - a place of education
The Helmholtz-Zentrum Berlin offers apprenticeships in ten professions. Seven chamber professions (office management assistants, precision mechanics, IT specialists...) and three dual study programmes. The international environment and the proximity to excellent science at the research centre are something very special. The instructors and training specialists impart sound knowledge and skills in the individual specialist areas.
In addition to HZB's social responsibility, engaging in apprenticeship enables one to find the best-fitting talents at an early stage and to bind new specialists to HZB already during their educational phase.
More details about apprenticeships and training at HZB can be found here.
- Perovskite triple-junction solar cells: Even more efficient with GO/SAM bilayersPerovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely lightweight. A team at HZB has developed a triple-junction solar cell comprising different perovskite semiconductors, with a novel bilayer of graphene oxide (GO) and a self-assembled monolayer (SAM) as the hole conductor. This bilayer significantly increases both efficiency and long-term stability. The efficiency of the novel perovskite triple-junction solar cell is 27.3% and shows hardly any decline even after more than 770 hours of operation. The study has been published in the renowned journal Joule.
- Green Deal Ukraїna at the Ukraine Recovery ConferenceEnd of June, the Ukraine Recovery Conference (UCR2026) took place in Gdańsk, Poland. Unlike previous editions, URC2026 introduced a dedicated Energy Platform, jointly organised by the Ministry of Energy of Ukraine and the Ministry of Climate and Environment of Poland, which brought together energy-related discussions, announcements, and side events in one place, increasing the visibility and coordination of key energy topics. Green Deal Ukraїna, an initiative coordinated by HZB, organised three events on the sidelines of URC on research and energy topics as part of the conference.
- Magnetic imaging: Micro-flowers increase the local magnetic fieldMaterials with magnetic nanostructures have many potential applications such as in spintronics. To explore such materials, nanoscale magnetic-sensitive imaging techniques are very useful, but up to now only weak magnetic fields could be applied during the imaging process. Now an international collaboration led by Dr. Sergio Valencia, HZB, has developed an approach that overcomes this limitation. The team designed tiny magnetic flux concentrators (MFCs), into which the sample is placed. The geometry of the MFCs resembles a flower with a number of petals which focus the applied magnetic field into its center. This greatly expands the magnetic field range available during imaging, and so the range of magnetic systems that can be investigated. The micro-flowers, enhancing magnetic fields locally, can find application in different nanometric magnetic microscopy techniques.
