On 25 and 26 November 2015, about 40 researchers from seven European countries visited Helmholtz-Zentrum Berlin to attend the “European Workshop on Nanophotonics for Solar Energy”.
During this workshop, current trends and developments in this field were discussed. Further, future opportunities and possibilities for collaboration were explored during discussions, which were initiated with a talk on funding within the European Commission Horizon 2020 program by Dr. David Kolman from the Brussels Office of the Helmholtz Association. The highlight of the workshop was the Distinguished Lecture by Prof. Thomas F. Krauss from the University of York (UK), in which he shared his vision on the future of Photovoltaics and informed us about the latest research results from his group.
This workshop was initiated and organized by Christiane Becker, Sven Burger and Klaus Jäger within the Berlin Joint Lab for Optical Simulations for Energy (BerOSE), which is a collaboration between Helmholtz-Zentrum Berlin, Zuse Institute Berlin and the Free University Berlin.
- 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.
- Successful master's degree in IR thermography on solar facadesWe are delighted to congratulate our student employee Luca Raschke on successfully completing her Master's degree in Renewable Energies at the Hochschule für Technik und Wirtschaft Berlin - and with distinction!
- TT-Award 2025: Perovskite solar cells from GermanyPhotovoltaics is the leading technology in the transition to clean energy. However, traditional silicon-based solar technology has reached its efficiency limit. Therefore, a HZB-team has developed a perovskite-based multi-junction cell architecture. For this, Kevin J. Prince and Siddhartha Garud received the Helmholtz-Zentrum Berlin's (HZB) Technology Transfer Prize of 5,000 euros.
