Excellent Master, Diploma, and PhD Students from all over the world from different disciplines are invited to participate in the international summer university ISUenergy2015. The ISUenergy2015 will take place from Aug. 23rd - Sept. 4th 2015 in Falera/Switzerland.
The interdisciplinary summer university focuses on solar energy under a multitude of perspectives: from the physics of photovoltaics and solar thermal energy to solar architecture and electromobility, smart grids and the economic and political aspects of renewable energy use. These topics will be treated in lectures, evening talks, practical workshops, and group projects.
This summer university is internationally established since 2009 and provides a unique setting for students to enrich their knowledge on energy topics. Splendid network opportunities among the students and with the lecturers will be offered.

- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
- Hatice Mutlu appointed to the Helmholtz Institute HIPOLE in JenaProf. Dr Hatice Mutlu is the new professor of sustainable polymer chemistry at HIPOLE Jena, the Helmholtz Institute for Polymers in Energy Applications. On 17 August 2026, she visited the HZB campus in Berlin-Adlershof including the BESSY II lightsource and discussed future collaboration with researchers and the board of directors.
- Green hydrogen with PEC electrolysers: New insights into transport processesOne method of storing solar energy is to use PEC electrolysers to produce hydrogen. However, scaling up this technology remains challenging. Now, a team at the HZB Institute for Solar Fuels has used 2D fluorescence imaging and particle velocimetry to observe the movement of ions and dissolved gases within the electrolyte during electrolysis. These new insights may prove useful in the development of larger PEC electrolysers.
