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.

- 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.
- Lithium-sulphur batteries with lean electrolyte: problem areas clarifiedUsing a non-destructive method, a team at HZB investigated practical lithium-sulphur pouch cells with lean electrolyte for the first time. With operando neutron tomography, they could visualise in real-time how the liquid electrolyte distributes and wets the electrodes across multilayers during charging and discharging. These findings offer valuable insights into the cell failure mechanisms and are helpful to design compact Li-S batteries with a high energy density in formats relevant to industrial applications.
