Johannes Sutter, PhD student at HZB, was awarded a poster prize at the "International Conference on Perovskite Solar Cells, Photonics and Optoelectronics (NIPHO19)". The conference took place from 25-27 February 2019 in Jerusalem.
Johannes Sutter is working on his PhD in the Nano-SIPPE group of Prof. Dr. Christiane Becker, his experimental work is done in the Helmholtz Innovation Lab HySPRINT at HZB. He won a poster prize at the first international conference at which he was able to present his work. The prize from the scientific publisher Wiley was associated with a book voucher worth 300 euros.
Sutter develops nanostructures at interfaces in perovskite-silicon tandem solar cells in order to facilitate spin coating of perovskite. These nanostructures should have low reflection values and good electronic properties.
By combining the processes of nanoimprint lithography and reactive ion etching, it is possible to transfer the nanostructures into crystalline silicon. Both optical and electronic investigations show that such interface structures can improve the properties of perovskite silicon tandem cells.
- New Helmholtz Young Investigator Group at HZB on perovskite solar cellsSilvia Mariotti is returning to HZB as head of the new Helmholtz Young Investigator Group ‘Perovskite-based multi-junction solar cells’. The perovskite expert, who was previously based at Okinawa University in Japan, aims to advance the development of multi-junction solar cells made from different perovskite layers.
- Hydrogen storage in MXene: It all depends on diffusion processesTwo-dimensional (2D) materials such as MXene are of great interest for hydrogen storage. An expert from HZB has investigated the diffusion of hydrogen in MXene using density functional theory. This modelling provides valuable insights into the key diffusion mechanisms and hydrogen's interaction with Ti₃C₂ MXene, offering a solid foundation for further experimental research.
- Excellent work-life balance continuesOn 17 June 2025, the certificates for the ‘berufundfamilie’ audit were awarded in Berlin. HZB received an award with distinction for its long-standing efforts to promote a work environment that supports work-life balance. The audit is regarded as a seal of quality for the systematic design of family- and life-phase-conscious HR policies.
