HZB has been certified as a family-friendly employer since 2011. Now the research centre has successfully completed the re-auditing process and developed further measures to promote a life phase conscious working culture. The certificate is considered a seal of quality for the company's compatibility policy and is awarded by the board of trustees of berufundfamilie Service GmbH.
In autumn 2020, HZB conducted an employee survey which showed that most employees are aware of and appreciate the numerous options HZB offers: flexible working hours, mobile working, part-time models, advice and practical help for employees with care responsibilities or small children.
At the same time, the survey made it clear that the needs of many employees in terms of compatibility have increased - not only, but also because of Corona. The need for support, especially for people with family responsibilities, has increased in the past year. Anja Seehrich, who heads the Office for Work and Life (OWL) at HZB, has also noticed this in her consultations. "Most are glad to work at HZB because they can count on a lot of understanding and practical support here."
Over the next three years, HZB will establish further measures that employees and managers worked out together. These include, among other things, reviewing the existing rules on home office, management guidelines and raising awareness of mental and physical diseases.
- Long-term test shows: Efficiency of perovskite cells varies with the seasonScientists at HZB run a long-term experiment on the roof of a building at the Adlershof campus. They expose a wide variety of solar cells to the weather conditions, recording their performance over a period of years. These include perovskite solar cells, a new photovoltaic material offering high efficiency and low manufacturing costs. Dr Carolin Ulbrich and Dr Mark Khenkin evaluated four years of data and presented their findings in Advanced Energy Materials. This is the longest series of measurements on perovskite cells in outdoor use to date. The scientists found that standard perovskite solar cells perform very well during the summer months, even over several years, but decline in efficiency during the darker months.
- Sodium-ion batteries: New storage mechanism for cathode materialsLi-ion and Na-ion batteries operate through a process called intercalation, where ions are stored and exchanged between two chemically different electrodes. In contrast, co-intercalation, a process in which both ions and solvent molecules are stored simultaneously, has traditionally been considered undesirable due to its tendency to cause rapid battery failure. Against this traditional view, an international research team led by Philipp Adelhelm has now demonstrated that co-intercalation can be a reversible and fast process for cathode materials in Na-ion batteries. The approach of jointly storing ions and solvents in cathode materials provides a new handle for designing batteries with high efficiency and fast charging capabilities. The results are published in Nature Materials.
- 10 million euros in funding for UNITE – Startup Factory Berlin-BrandenburgUNITE – Startup Factory Berlin-Brandenburg has been recognised by the Federal Ministry for Economic Affairs and Energy as one of ten nationwide flagship projects for science-based start-ups. UNITE is to be established as a central transfer platform for technology-driven spin-offs from science and industry in the capital region. The Helmholtz Centre Berlin will also benefit from this.
