Helmholtz Innovation Labs: HySPRINT at HZB
HZB will be setting up the new Helmholtz HySPRINT Innovation Lab for jointly developing new combinations of materials and processes in energy applications with commercial partners. Silicon and metal-organic perovskite crystals will be the centre point of the Lab’s work. The Helmholtz Association is supporting the project for the next five years with 1.9 million Euros from its Initiative and Networking Fund, with additional contributions from HZB itself as well as from industry.
The Helmholtz Association is supporting a total of seven Helmholtz Innovation Labs in order to strengthen the transfer of research results to the applications domain. The Association is making about twelve million Euros available over the next five years for setting up and operating the Innovation Labs.
The HZB proposal was selected from a field of 27 competing applications. HySPRINT stands for “Hybrid Silicon Perovskite Research, Integration & Novel Technologies”. It will focus on hybrid materials and components based on silicon and perovskite crystals able to be employed for energy conversion in photovoltaics as well as for solar hydrogen production.
“We intend to further develop silicon hybrid technology, liquid-phase crystallisation of silicon, nano-print lithography as well as the implementation of prototypes by means of 3D techniques for microcontacts in cooperation with industrial partners – and demonstrate the potential for industrial-scale production”, says Professor Bernd Rech from the HZB Institute for Silicon Photovoltaics.
The Innovation Lab will be set up as a core lab at HZB and will work closely with the HZB Institute PVcomB. Professor Anke Kaysser-Pyzalla, Scientific Director of HZB poitbs out: “HySPRINT will establish itself as a creative pillar of Technology Transfer at HZB and within the Helmholtz Association.”
- Thin nickel films boost green hydrogen productionUltra-thin nickel oxide coatings can significantly improve the performance of anion exchange membrane (AEM) water electrolysers, a promising technology for producing green hydrogen. This was demonstrated by a team led by HZB scientist Dr. Michelle Browne. The results show that a nickel oxide film only 10 nanometres thick outperformed conventional nickel oxide powder electrodes while using less than 1% of the catalyst material. The study is published in the Journal of Materials Chemistry A,
- Detailed insights at BESSY II into the oxidation processes of copperBefore pure copper oxide builds up, complex superstructures such as ‘29’CuxO, are formed. The new results on the '29' CuxO superstructure have relevance for catalyst research and corrosion protection in the development of safe copper containers for nuclear waste repositories.
- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
