The CUSTOM-ART consortium consists of 17 academic and industrial partners, involving world leading groups and main European actors involved in the development of kesterite technologies. It leads an ambitious and disruptive project for the development and demonstration of the next generation of building and product integrated photovoltaic modules (BIPV and PIPV) based on abundant thin-film materials. The project started September, 1st 2020 and will run for 3.5 years.
HZB contributes to the technology development by systematically investigating the structure-function relationship of kesterite-type materials as one of quaternary chalcogenide compound semiconductors. HZB will study the influence of alkali doping on the point defect scenario and level of structural disorder. These studies will rely on detailed structural investigations of kesterite-type monograins (based on neutron diffraction and multiple energy anomalous X-ray diffraction). Also HZB will contribute with combinatorial high-throughput materials optimization applying especially advanced optoelectronic analytics. HZB has a share of 550 TEUR out of the total funding based on budgeted total costs of 8M€.
- Susanne Nies appointed to EU advisory group on Green DealDr. Susanne Nies heads the Green Deal Ukraina project at HZB, which aims to support the development of a sustainable energy system in Ukraine. The energy expert has now also been appointed to the European Commission's scientific advisory group to comment on regulatory burdens in connection with the net-zero target (DG GROW).
- The future of corals – what X-rays can tell usThis summer, it was all over the media. Driven by the climate crisis, the oceans have now also passed a critical point, the absorption of CO2 is making the oceans increasingly acidic. The shells of certain sea snails are already showing the first signs of damage. But also the skeleton structures of coral reefs are deteriorating in more acidic conditions. This is especially concerning given that corals are already suffering from marine heatwaves and pollution, which are leading to bleaching and finally to the death of entire reefs worldwide. But how exactly does ocean acidification affect reef structures?
Prof. Dr. Tali Mass, a marine biologist from the University of Haifa, Israel, is an expert on stony corals. Together with Prof. Dr. Paul Zaslansky, X-ray imaging expert from Charité Berlin, she investigated at BESSY II the skeleton formation in baby corals, raised under different pH conditions. Antonia Rötger spoke online with the two experts about the results of their recent study and the future of coral reefs.
- Long-term stability for perovskite solar cells: a big step forwardPerovskite solar cells are inexpensive to produce and generate a high amount of electric power per surface area. However, they are not yet stable enough, losing efficiency more rapidly than the silicon market standard. Now, an international team led by Prof. Dr. Antonio Abate has dramatically increased their stability by applying a novel coating to the interface between the surface of the perovskite and the top contact layer. This has even boosted efficiency to almost 27%, which represents the state-of-the-art. After 1,200 hours of continuous operation under standard illumination, no decrease in efficiency was observed. The study involved research teams from China, Italy, Switzerland and Germany and has been published in Nature Photonics.
