Dr. Feng Liang has joined the HZB Institute Solar Fuels in 2021. Now, he has secured an associate professorship at the Green Hydrogen Innovation Center in the Department of Mechanical Engineering, Xi'an Jiaotong University, China. He will start to build up his research team in June 2025.
Dr. Feng Liang has earned a PhD in mechanical engineering from Xi'an Jiaotong University, China, in a joint training programme with RWTH Aachen. In October 2021, he joined the Institute Solar Fuels on a Helmholtz-Innovation Pool project. He is developing cutting-edge prototypes for water-splitting devices that can operate at higher than ambient pressures up to 8 bar.
The design of functioning prototypes demands skills from different disciplines, not only device engineering but as well a deep understanding of materials science and electrochemistry. “I learned most of the electrochemistry here from Fatwa Abdi and Roel van de Krol”, Liang says. “They were the best mentors I could ever imagine”.
Feng Liang has secured an associate professorship at the Department of Mechanical Engineering in Xi'an Jiaotong University. He will leave HZB after helping his colleagues prepare for the "programme oriented funding" evaluation in May.
“From June 2025, I will start my own group in China, and I'm excited about the prospect of a close partnership with HZB in the future”, he says. Liang will continue his work on prototypes for water splitting. Roel van de Krol, director of the Institute for Solar Fuels, praised Feng Liang's achievement, saying: “It's wonderful to see that his work at HZB has led to an associate professorship; it's a great example of how HZB provides a supportive environment for early-career researchers to develop their careers”.
- Precision interface chemistry pushes perovskite solar cells beyond 26% efficiencyAn international research collaboration has developed a new molecular strategy for controlling one of the most critical interfaces in perovskite solar cells. The resulting solar cells reached a power conversion efficiency of 26.19% in the n i p architecture, together with strong operational stability under prolonged illumination and elevated temperature. The results have been published in the Journal of the American Chemical Society.
- Perovskite triple-junction solar cells: Even more efficient with GO/SAM bilayersPerovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely lightweight. A team at HZB has developed a triple-junction solar cell comprising different perovskite semiconductors, with a novel bilayer of graphene oxide (GO) and a self-assembled monolayer (SAM) as the hole conductor. This bilayer significantly increases both efficiency and long-term stability. The efficiency of the novel perovskite triple-junction solar cell is 27.3% and shows hardly any decline even after more than 770 hours of operation. The study has been published in the renowned journal Joule.
- Green Deal Ukraїna at the Ukraine Recovery ConferenceEnd of June, the Ukraine Recovery Conference (UCR2026) took place in Gdańsk, Poland. Unlike previous editions, URC2026 introduced a dedicated Energy Platform, jointly organised by the Ministry of Energy of Ukraine and the Ministry of Climate and Environment of Poland, which brought together energy-related discussions, announcements, and side events in one place, increasing the visibility and coordination of key energy topics. Green Deal Ukraїna, an initiative coordinated by HZB, organised three events on the sidelines of URC on research and energy topics as part of the conference.
