AMOLF welcomes Wiebke Albrecht

On May 1st, Wiebke Albrecht will start at AMOLF as tenure track group leader. Her research group Hybrid Nanosystems will be embedded in the Designer Matter research theme at AMOLF. With her group, Albrecht will investigate the interaction between different components in complex hybrid nanosystems, such as metal-semiconductor nanostructures. By combining advanced electron microscopy and single particle optical spectroscopy on the same nanoparticle, she will be able to unravel the interplay of morphology and underlying charge and energy transfer processes. The ultimate goal is to develop new concepts of hybrid architectures, responsive to external stimuli, with properties specifically tailored for applications in solar energy harvesting and quantum information processing.

During her PhD at the Soft Condensed Matter group headed by Prof. Alfons van Blaaderen at Utrecht University, Albrecht worked on laser modification and plasmonic properties of anisotropic metal nanoparticles. Afterwards, she moved to the Electron Microscopy for Material Science group at the University of Antwerp and worked on in situ nanoparticle transformations studied in 3D by electron tomography. With a Marie Skłodowska-Curie Individual Fellowship, which she partially conducted at the Single-Molecule Optics group of Prof. Michel Orrit at Leiden University, she could combine her interest in advanced electron microscopy and single particle optical spectroscopy.

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).
