HZB has signed the “Charta der Vielfalt” (Diversity Charter)

HZB is an employer that comprehensively strengthens and cares for the diversity of its employees. HZB publicly acknowledges this by signing the Diversity Charter. The charter is run by an association that works to anchor diversity in the working world.
By signing, HZB commits to the following goal:
"At HZB, we promote and value the diversity of our employees. Diversity creates new opportunities for cooperation and creativity for science. Tapping into these potentials and making them sustainable elements of the work culture is our goal."
Here you get to the HZB entry of the Diversity Charter.
The Helmholtz-Zentrum Berlin (HZB) was the first non-university research institution to undergo the Stifterverband's diversity audit "Shaping Diversity." The certification attests to the HZB's opportunity-oriented concepts and measures for diverse groups of people.
Diversity Charter
4500 companies and institutions have signed the Diversity Charter to date and are committed to an appreciative and prejudice-free working environment. The association thus represents 14.6 million employees in Germany. Here you find the "Diversity Charter in wording" document.
German Diversity Day 2022
Diversity Day will be held for the 10th time in Germany on May 31. HZB will also participate and show its colours! More about this in the near future.
- New contact material boosts the efficiency of perovskite solar cellsA newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several advantages over the standard material C60, as shown by the study led by Steve Albrecht’s team. The new material has since been patented and is already commercially available.
- Precision interface chemistry pushes perovskite solar cells beyond 26% efficiencyAn international research collaboration has developed a new molecular strategy for controlling one of the most critical interfaces in perovskite solar cells. The resulting solar cells reached a power conversion efficiency of 26.19% in the n i p architecture, together with strong operational stability under prolonged illumination and elevated temperature. The results have been published in the Journal of the American Chemical Society.
- 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.
