On Monday, August 5, 2013, a festive groundbreaking ceremony was the official signal for the start of construction of the new BESSY II research lab EMIL. The new cutting-edge solar energy and catalysis research preparation and analysis lab "Energy Materials In-Situ Laboratory Berlin" will be a direct BESSY II add-on. The joint project by the HZB and the Max Planck Society provides a one-of-a-kind infrastructure for the interdisciplinary and industry compatible development of new materials and technologies to facilitate the energy transition. This includes new material systems for solar modules as well as storage solutions for which new kinds of catalysts are warranted.
"Construction of EMIL is a sure-fire sign of the HZB's commitment to expanding our energy research focus. These kinds of unparalleled infrastructures are an important prerequisite for energy technology progress," said Prof. Anke-Rita Kaysser-Pyzalla, the HZB's scientific director. She took the occasion to thank all those involved at the HZB, the project executing organisation Jülich, the funding bodies as well as the various agencies for their formidable commitment to preparing and supporting the building project.
In his speech, the head of the project, Prof. Klaus Lips, made reference to the young hero in Erich Kästner's children's classic "Emil and the detectives," who personifies the new lab's mission. "Just as Emil went out looking for allies, here, too, it's all about putting together a strong team and figuring out solar cell losses using scientific detective work," Lips explained. "Beginning in 2015, we will be able to use EMIL for analysing the different processes that take place at the interfaces during production of thin film solar cells or catalysts under real-life conditions and even use depth-resolved observation."
Next, head architect Markus Hammes commented on the building's design: "We made a conscious effort to model the EMIL building on the storage ring's form language so EMIL will have the appearance of a pulled-out drawer as an integral part of the BESSY II building, albeit with its own separate function."
Lastly, Dr. Gerd Reichardt, EMIL's technology project manager, stuffed a time capsule made from solid stainless steel with a copy of Erich Kästner's novel, the daily paper, and the building blueprints, as well as with several samples of cutting-edge thin film photovoltaics, and then buried it in the ground underneath the construction site. The topping out ceremony has been scheduled for end-of-year 2013 to ensure the labs are up and running by late 2014.
- Electrocatalysts: New model for charge separation at the solid-liquid interfaceHydrogen is at the heart of the transition to carbon neutrality, as both an energy carrier and a reagent for green chemistry. However, large-scale production of hydrogen via electrolysis, as well as the production of many other chemical products, requires significantly cheaper and more efficient catalysts. A precise understanding of the electrochemical processes that take place at the interface between the solid catalyst and the liquid medium is highly useful for developing better electrocatalysts. In the journal Nature Communications, an European team has now presented a powerful model that determines charge separation at the interface, the formation of the electric double layer and local electric potential variations, and the resulting influence on the catalytic activity.
- Environmental Chemistry at BESSY II: Radicals in waterwaysHow do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection, for example with regard to the overfertilisation of water bodies by intensive agriculture. A team at BESSY II has now developed a new method of investigating hydroxyl radicals in solution. By using a clever trick, the scientists gained surprising insights into the reaction pathway.
