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.
- Industrial Research Fellow at HZB: More time for discussionsThe South African chemist Denzil Moodley is the first Industrial Research Fellow at HZB. He is playing a leading role in the CARE-O-SENE project. The Fellowship program aims to further accelerate the development of an efficient catalyst for a sustainable aviation fuel. An interview about the CARE-O-SENE project and why it is so important for scientists from industry and public research to work together.
- Perovskites: Hybrid materials as highly sensitive X-ray detectorsNew bismuth-based organic-inorganic hybrid materials show exceptional sensitivity and long-term stability as X-ray detectors, significantly more sensitive than commercial X-ray detectors. In addition, these materials can be produced without solvents by ball milling, a mechanochemical synthesis process that is environmentally friendly and scalable. More sensitive detectors would allow for a reduction in the radiation exposure during X-ray examinations.
- Electrical energy storage: BAM, HZB, and HU Berlin plan joint Berlin Battery LabThe Federal Institute for Materials Research and Testing (BAM), the Helmholtz-Zentrum Berlin (HZB), and Humboldt University of Berlin (HU Berlin) have signed a memorandum of understanding (MoU) to establish the Berlin Battery Lab. The lab will pool the expertise of the three institutions to advance the development of sustainable battery technologies. The joint research infrastructure will also be open to industry for pioneering projects in this field.
