Johannes Sutter, PhD student at HZB, was awarded a poster prize at the "International Conference on Perovskite Solar Cells, Photonics and Optoelectronics (NIPHO19)". The conference took place from 25-27 February 2019 in Jerusalem.

Johannes Sutter is working on his PhD in the Nano-SIPPE group of Prof. Dr. Christiane Becker, his experimental work is done in the Helmholtz Innovation Lab HySPRINT at HZB. He won a poster prize at the first international conference at which he was able to present his work. The prize from the scientific publisher Wiley was associated with a book voucher worth 300 euros.

Sutter develops nanostructures at interfaces in perovskite-silicon tandem solar cells in order to facilitate spin coating of perovskite. These nanostructures should have low reflection values and good electronic properties.

By combining the processes of nanoimprint lithography and reactive ion etching, it is possible to transfer the nanostructures into crystalline silicon. Both optical and electronic investigations show that such interface structures can improve the properties of perovskite silicon tandem cells.

    Helmholtz Institute for Polymers in Energy Applications (HIPOLE Jena) Inaugurated
    On June 17, 2024, the Helmholtz Institute for Polymers in Energy Applications (HIPOLE Jena) was officially inaugurated in Jena in the presence of Wolfgang Tiefensee, Minister for Economy, Science, and Digital Society of the Free State of Thuringia. The institute was founded by the Helmholtz Center Berlin for Materials and Energy (HZB) in cooperation with the Friedrich Schiller University Jena. It is dedicated to developing sustainable polymer materials for energy technologies, which are expected to play a key role in the energy transition and support Germany’s goal of becoming climate-neutral by 2045.

    MXenes for energy storage: Chemical imaging more than just surface deep
    A new method in spectromicroscopy significantly improves the study of chemical reactions at the nanoscale, both on surfaces and inside layered materials. Scanning X-ray microscopy (SXM) at MAXYMUS beamline of BESSY II enables the investigation of chemical species adsorbed on the top layer (surface) or intercalated within the MXene electrode (bulk) with high chemical sensitivity. The method was developed by a HZB team led by Dr. Tristan Petit. The scientists demonstrated among others first SXM on MXene flakes, a material used as electrode in lithium-ion batteries.
