Javier Villalobos has been awarded for the best poster at the International Workshop on Correlated Dynamics in Energy Conversion (IWCE 19) in Göttingen. The doctoral student works in the young investigator group "Oxygen Evolution Mechanism Engineering". His research contributes to a better understanding of electrocatalytic oxygen evolution.

On his poster, Javier Villalobos presented first results on the electrochemical synthesis of spinel oxides, which can be used as catalysts for the oxygen evolution reaction. The title of his poster is "Fabrication of defined spinel oxides containing manganese and cobalt by electrodeposition as model electrodes for the oxygen evolution reaction".

The presented results are the first step towards developing a model system for systematic studies on such catalysts. It is crucial to deposit films with controlled composition and microstructure. These materials will soon be investigated using operando methods on BESSY II to better understand the known differences in activity.

"With his poster, Javier Villalobos laid the foundation for a better understanding of the oxygen evolution reaction in order to produce sustainable fuels based on water (e.g. hydrogen) more cheaply," explains Dr. Marcel Risch, supervisor of the project. Since March 2019, he has been setting up a young investigator group at HZB with a Starting Grant from the European Research Council (ERC).

    Special prize by Jugend Forscht awarded to former school intern
    Shaoxuan Wang has won a special prize in the Jugend Forscht competition for her project ‘Smart Capsules – intelligent microcapsules for glucose-dependent insulin release’. She designed the project as a “special achievement” for her A-levels. To carry out the experimental work, Shaoxuan was able to spend a further two weeks in the laboratory at the HZB Institute for Electrochemical Energy Storage, where she had completed a school internship two years earlier.

    Green hydrogen with PEC electrolysers: New insights into transport processes
    One method of storing solar energy is to use PEC electrolysers to produce hydrogen. However, scaling up this technology remains challenging. Now, a team at the HZB Institute for Solar Fuels has used 2D fluorescence imaging and particle velocimetry to observe the movement of ions and dissolved gases within the electrolyte during electrolysis. These new insights may prove useful in the development of larger PEC electrolysers.

    New contact material boosts the efficiency of perovskite solar cells
    A newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several advantages over the standard material C60, as shown by the study led by Steve Albrecht’s team. The new material has since been patented and is already commercially available.
