Ideally, when research teams submit a particularly important paper, they share it with the comms team. Then it is usually my turn to take over and write a science highlight. It’s a short, highly simplified text, optimised for quick and easy reading. Publications of 30 or more pages are condensed into one page, leaving out a lot, however the motivation and relevance of the research should come across clearly.

Of course, our science news also end up on many other websites and platforms, additionally we distribute them through different channels and ensure dissemination. It is difficult to determine exactly how often they are accessed there. Probably many times over.

Outreach needs time – why bother?

Sometimes researchers want to know: Where is the benefit asking the Comms team to highlight my paper? It is time consuming for the scientists: they have to explain what is particularly important in the paper, provide nice illustrations and check the drafts. In fact, it’s all about getting attention! Not necessarily through the mass media: the topics of our research are often too specific for that. But certainly, among the science community, science management and politics. After all, who still manages to read the original publications on a broader field of knowledge? Short science news can provide a rough overview and perhaps even help to discover interesting methods in related fields.

Altmetric counts how often the DOI is mentioned in social media

Many – but not all – publishers display both the accesses of publications and the frequency with which the Digital Object Identifier(DOI) appears on the web. This last indication is collected by Altmetric. It takes into account Twitter, Reddit, Mendeley, Facebook, blogs and news sites on the web that reference the original publication with the DOI.

After a science highlight goes online, these Altmetric numbers often rise sharply and this also seems to correlate with accesses of the publications.

The 3 publications with the highest Altmetric scores in 2022 have also been retrieved many thousands of times. They are among the top 2% of all publications in the respective journal. Among the 43 science highlights on the HZB website in 2022, a further 30 publications have managed to score among the top 5%. (as of 21.12.2022).

Great research deserves to be seen

Of course, one can debate what such numbers say. It is always possible that outstanding research is initially overlooked and only recognised over time by the science community. But to recognise and evaluate scientific results, the first step is always: to be aware of their existence.

    Perovskite triple-junction solar cells: Even more efficient with GO/SAM bilayers
    Perovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely lightweight. A team at HZB has developed a triple-junction solar cell comprising different perovskite semiconductors, with a novel bilayer of graphene oxide (GO) and a self-assembled monolayer (SAM) as the hole conductor. This bilayer significantly increases both efficiency and long-term stability. The efficiency of the novel perovskite triple-junction solar cell is 27.3% and shows hardly any decline even after more than 770 hours of operation. The study has been published in the renowned journal Joule.

    Magnetic imaging: Micro-flowers increase the local magnetic field
    Materials with magnetic nanostructures have many potential applications such as in spintronics. To explore such materials, nanoscale magnetic-sensitive imaging techniques are very useful, but up to now only weak magnetic fields could be applied during the imaging process. Now an international collaboration led by Dr. Sergio Valencia, HZB, has developed an approach that overcomes this limitation. The team designed tiny magnetic flux concentrators (MFCs), into which the sample is placed. The geometry of the MFCs resembles a flower with a number of petals which focus the applied magnetic field into its center. This greatly expands the magnetic field range available during imaging, and so the range of magnetic systems that can be investigated. The micro-flowers, enhancing magnetic fields locally, can find application in different nanometric magnetic microscopy techniques.

    CIGS-perovskite tandem cell achieves record efficiency of 25.5 %
    A Berlin-based team from HZB and Center for the Science of Materials Berlin (CSMB) at the Humboldt-Universität zu Berlin has set a new record for a tandem solar cell. Using a combination of a CIGS semiconductor layer and perovskite, along with several optimised intermediate layers, they were able to convert 25.5% of sunlight into electrical energy. The previous record for this combination of materials and this size of cell stood at 24.6%. The new record has been certified and is visible in the prestigious Solar Cell Efficiency Tables (the "Green Tables"), which serve as the definitive ledger for the global photovoltaic community.
