HZB Researcher on the Board of Directors of the Materials Research Society
Catherine Dubourdieu is head of the IFOX Institute at HZB and was elected now into the board of directors of the MRS.
In September 2019, Prof. Dr. Catherine Dubourdieu was elected into the Board of Directors of the Materials Research Society (MRS). The MRS is one of the largest scientific associations and has almost 14000 members from various areas of the natural sciences and engineering.
Catherine Dubourdieu heads the HZB-Institute IFOX (Functional Oxides for Energy Efficient Information Technology) and holds a professorship at the Freie Universität Berlin. She investigates the growth and properties of functional oxides and semiconductor materials with the aim of developing energy-efficient devices for information technology, that can be integrated on silicon chips. Over the past 15 years, the physicist has also established numerous collaborations with industry and holds 10 patents. She has already published over 140 articles in peer-review journals and has an excellent international network.
In the Materials Research Society Catherine Dubourdieu has been active for over 20 years, also in responsible functions. As of 2020, Catherine Dubourdieu will be a member of the MRS Board of Directors to support the global materials research community and provide a framework for the various disciplines to collaborate.
The MRS's mission is to advance international interdisciplinary materials research and technology for the benefit of the human society. It was founded in 1973 and today has around 14000 members from various areas of the natural sciences and engineering. The governance of the Society is the responsibility of the Board of Directors, composed of 6 officers and 18 directors, 15 of whom are elected by the membership. One third of the Board is renewed each year. Catherine Dubourdieu will serve in this position over the next three years.
- Bright prospects for tin perovskite solar cellsPerovskite solar cells are widely regarded as the next generation photovoltaic technology. However, they are not yet stable enough in the long term for widespread commercial use. One reason for this is migrating ions, which cause degradation of the semiconducting material over time. A team from HZB and the University of Potsdam has now investigated the ion density in four different, widely used perovskite compounds and discovered significant differences. Tin perovskite semiconductors produced with an alternative solvent had a particular low ion density — only one tenth that of lead perovskite semiconductors. This suggests that tin-based perovskites could be used to make solar cells that are not only really environmentally friendly but also very stable.
- Joint Kyiv Energy and Climate Lab goes liveHelmholtz-Zentrum Berlin and the National University of Kyiv-Mohyla Academy established on 27 November a Joint Energy and Climate Lab.
- How carbonates influence CO2-to-fuel conversionResearchers from the Helmholtz Zentrum Berlin (HZB) and the Fritz Haber Institute of the Max Planck Society (FHI) have uncovered how carbonate molecules affect the conversion of CO2 into valuable fuels on gold electrocatalysts. Their findings reveal key molecular mechanisms in CO2 electrocatalysis and hydrogen evolution, pointing to new strategies for improving energy efficiency and reaction selectivity.
