Phys.org: Engineers design nanostructured diamond metalens for compact quantum technologies
The practical challenge of collecting information from a single atom deep inside a crystal is a daunting one, however. Penn Engineers addressed this problem in a recent study in which they devised a way to pattern the surface of a diamond that makes it easier to collect light from the defects inside. Called a metalens, this surface structure contains nanoscale features that bend and focus the light emitted by the defects, despite being effectively flat. Source: Phys.org

Joining forces to study perovskite interfaces
AMOLF group leaders Professor Wiebke Albrecht and Professor Bruno Ehrler have received an NWO ENW-M2 grant for their joint research project, The Dynamic Atomic Interface between Halide Perovskites and Metals. The insights gained will pave the way for sustainable, high-performance solar energy and information technology. Wiebke and Bruno will each hire a PhD student for this project. The grant amounts to €800.000.
Wim Noorduin and Arian van Asten presenting their scientific journey
On October 8, Professor Wim Noorduin and his collaborator Professor Arian van Asten (University of Amsterdam) presented their scientific journey in a video to the audience at the ‘Avond van Wetenschap en Maatschappij’. They did so alongside the other nominees for the Huibregtsen Prize.
Natural phenomena ‘hyperuniform disorder’ enables highly efficient, thin silicon solar cells
Silicon solar panels are rigid and heavy, and many rooftops cannot support them. This creates a need for thin, flexible solar cells that can be integrated into building materials. However, making silicon solar cells thinner makes it harder to trap light inside the material. Researchers in the 3D Photovoltaics group found a fascinating way to overcome this challenge using a phenomenon called hyperuniform disorder. They publish their findings in the journal ACS Photonics.
The researchers were able to make highly efficient silicon solar cell materials that are 30 times thinner than conventional ones. They managed to do this by integrating a layer of nanometer sized structures on top of the material. Up close, this pattern looks random, but it is remarkably when you step back: no clumps, no gaps, and no repeating pattern. This is called hyperuniform disorder (or HUD).
