Six young researchers received a Hanwha Q-Cells Quantsol Award for their self-developed Photovoltaics. This award is presented by the organizers of the international summer school Quantsol together with the industry.
The International Summer School on Photovoltaics and New Concepts of Quantum Solar Energy Conversion (Quantsol) took place from 2 to 9 September 2018 in Hirschegg / Kleinwalsertal, Austria, for the eleventh time in a row. More than 50 prospective solar researchers from 20 countries attended the event. The participants received a comprehensive introduction into photovoltaics and solar fuel generation. Experts from leading research institutes all over the world presented the basic processes for converting solar energy into chemical and electrical energy and showed ways to their technical application. Newer materials, such as the promising perovskites or oxides for water splitting, as well as special analytical methods were also discussed in detail.
As last year, the Hanwha Q-Cells Quantsol Prize (QHQC Award 2018, see photo), was awarded in four categories. The winners in the team categories were Gizem Birant (University of Hasselt, Belgium) and Alejandra Villanueva Tovar (HZB) for the best self-built solar cell and Pavlo Perkhun (CINaM - Centre Interdisciplinaire de Nanoscience de Marseille, France) and Harald Reinhold (Carl von Ossietzky University of Oldenburg) for the best optical simulation of a perovskite silicon tandem solar cell. In the individual category, the prize went to the most active participant Erin Looney (MIT, USA) and Tom Veeken (AMOLF, Netherlands) for the best single crystal produced with the Epi-Simulator.
“We would like to thank all the helpers from the HZB and the TU Ilmenau as well as both research institutions, without whom it would not have been possible to organize and carry out such a high-quality school," said Prof. Klaus Lips, who – together with Prof. Thomas Hannappel, TU Ilmenau, is organizing this summerschool since eleven years. Due to the great demand, the next Quantsol Summer Schools are planned for September 2019 and 2020.
- Porous Radical Organic framework improves lithium-sulphur batteriesA team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulphur batteries. The material is based on polymers that form a framework with open pores (known as radical-cationic covalent organic frameworks or COFs). Catalytically accelerated reactions take place in these pores, firmly trapping polysulphides, which would shorten the battery life. Some of the experimental analyses were conducted at the BAMline at BESSY II.
- Shedding light on insulators: how light pulses unfreeze electronsMetal oxides are abundant in nature and central to technologies such as photocatalysis and photovoltaics. Yet, many suffer from poor electrical conduction, caused by strong repulsion between electrons in neighboring metal atoms. Researchers at HZB and partner institutions have shown that light pulses can temporarily weaken these repulsive forces, lowering the energy required for electrons mobility, inducing a metal-like behavior. This discovery offers a new way to manipulate material properties with light, with high potential to more efficient light-based devices.
- Key technology for a future without fossil fuelsIn June and July 2025, catalyst researcher Nico Fischer spent some time at HZB. It was his sabbatical, he was relieved of his duties as Director of the Catalysis Institute in Cape Town for several months and was able to focus on research only. His institute is collaborating with HZB on two projects that aim to develop environmentally friendly alternatives using innovative catalyst technologies. The questions were asked by Antonia Rötger, HZB.
