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.
- Two winning entries from the HZB in the Helmholtz Imaging ContestA time resolved X-ray tomography by Paul H. Kamm, HZB, has won the second Jury prize and is the winner of the Helmholtz Imaging conference Partizipants Choice Award in this year’s competition. It shows a 3D snapshot of a laser welding process. Among the 20 most beautiful images is also a microscopy image of a solar cell by Yannic Kerkhoff and Daniel Abou Ras, HZB.
- Israel Ibukun Olaniyan receives the Helmholtz Doctoral Prize 2026At Helmholtz, more than 8,000 doctoral candidates conduct research. Eleven of them have now been honored for their original and outstanding work, among them Dr Israel Ibukun Olaniyan from the HZB. His doctoral thesis "Ferroelectricity at the nanoscale in epitaxial BaTiO3 on silicon" in the group of Professor Catherine Dubourdieu represents a step towards a new nanoelectronics based on topological defects, that can potentially help to create an energy efficient information technology.
- HZB congratulates Peter Hegemann on winning the Nobel PrizeOur warmest congratulations go to Peter Hegemann, Professor of Neuroscience and Experimental Biophysics at Humboldt University in Berlin. Together with Prof. Georg Nagel (Julius Maximilian University of Würzburg) and Prof. Karl Deisseroth (Stanford University, USA), he has been awarded the 2026 Nobel Prize in Physiology or Medicine. We are delighted for him, his team, Humboldt University and the entire Berlin scientific community.
