Every year, countless articles are published in specialist journals. The information service provider Clarivate uses a recognised method to measure the influence of the published articles on the respective subject area. According to this year's evaluation, HZB researcher Steve Albrecht is one of the most "highly cited researchers" having a significant influence on his field. Albrecht and his team have been involved in several world records for tandem solar cells in recent years and have published the results in high-ranking scientific journals.
Only one in 1000 active researchers belongs to the circle of “Highly Cited Researchers”. Over the past ten years, those selected have produced a number of excellent publications that other work can build on and which are therefore frequently cited. However, citation activity is not the only selection indicator, writes Clarivate, a company that analyses the Web of Science: For example, publications that show evidence of citation cartels or self-citations have been weeded out. This year, 6,849 researchers from 68 countries and regions were honoured.
From the Helmholtz-Zentrum Berlin, Prof. Dr Steve Albrecht was identified as a “Highly Cited Researcher”. Albrecht leads a team researching perovskite materials for solar cells. Together with other groups at HZB and partner institutions, he has set several world records for the efficiency of tandem solar cells. His research is widely recognised, as evidenced by the “Highly Cited Researchers” award, and is making a significant contribution to the advancement of research in solar energy.
Note: HZB researcher Antonio Abate is also one of the "Highly Cited Researchers 2023", albeit not as an HZB researcher, but with an affiliation to one of his previous academic stations. Abate is also researching perovskite solar cells, which makes HZB perovskite research visible worldwide.
- 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.
- Peat as a sustainable precursor for fuel cell catalyst materialsIron-nitrogen-carbon catalysts have the potential to replace the more expensive platinum catalysts currently used in fuel cells. This is shown by a study conducted by researchers from the Helmholtz-Zentrum Berlin (HZB), Physikalisch-Technische Bundesanstalt (PTB) and universities in Tartu and Tallinn, Estonia. At BESSY II, the team observed the formation of complex microstructures within various samples. They then analysed which structural parameters were particularly important for fostering the preferred electrochemical reactions. The raw material for such catalysts is well decomposed peat.
- Helmholtz Investigator Group on magnonsDr Hebatalla Elnaggar is setting up a new Helmholtz Investigator Group at HZB. At BESSY II, the materials scientist will investigate so-called magnons in magnetic perovskite thin films. The aim is to lay the foundations for future terahertz magnon technology: magnonic devices operating in the terahertz range could process data using a fraction of the energy required by the most advanced semiconductor devices, and at speeds up to a thousand times faster.
