HZB re-certified as a compatibility-friendly company again

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.

New contact material boosts the efficiency of perovskite solar cells
A 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% efficiency
An 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 bilayers
Perovskite 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.
