Intersolar Europe in Munich: HZB research meets solar industry
Intersolar Europe is the world’s leading exhibition for the solar industry and its partners and takes place annually at the Messe München exhibition center in Munich, Germany.

At the major international photovoltaics exhibition from 31 May to 2 June 2017, Helmholtz-Zentrum Berlin (HZB) will be exhibiting solar energy research projects and presenting opportunities for industrial cooperation in the field of photovoltaics (PV).
Intersolar Europe is a world leading event where manufacturers, suppliers, distributors and service providers come to learn of new developments in the solar industry. A team from Helmholtz-Zentrum Berlin will be presenting its research in the field of renewable energies at this exhibition in Hall A2, Booth 574 – in particular, the new Helmholtz Innovation Lab HySPRINT and the long-established competence centre for photovoltaics PVcomB. These two institutes primarily address the scientific-technical issues of technology transfer and cooperate closely with industrial partners.
In the Helmholtz Innovation Lab HySPRINT, silicon-based materials are being combined with organometallic perovskite crystals to develop so-called hybrid tandem cells. Such cells can be used for solar generation of electricity or hydrogen.
The Competence Centre Thin-Film- and Nanotechnology for Photovoltaics Berlin (PVcomB) has industrial reference lines for manufacturing CIGS and silicon photovoltaics. Teams of HZB experts are collaborating with industry to develop novel thin-film technologies and products. Joint research projects with industrial partners have already culminated in many successful innovations.
Research into new material systems for photovoltaics is an important focal topic at HZB. The Centre is specialised in so-called energy materials that convert or store energy. This includes solar cells, material systems for generating hydrogen from sunlight, and magnetic material systems for developing energy-efficient information technologies. For studying interfaces and surfaces of thin films, HZB operates the photon source BESSY II and a series of CoreLabs with latest generation equipment.
HZB’s info stand is in Hall A2, Booth 574 (A2.574)
- 5000th patient treated with protons for eye tumoursFor more than 20 years, Charité – Universitätsmedizin Berlin and the Helmholtz-Zentrum Berlin (HZB) have been jointly offering proton radiation therapy for eye tumours. The HZB operates a proton accelerator in Berlin-Wannsee for this purpose, while Charité provides medical care for the patients. The 5000th patient was treated at the beginning of August.
- 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.
- Self assembling monolayer can improve lead-free perovskite solar cells tooTin perovskite solar cells are not only non-toxic, but also potentially more stable than lead-containing perovskite solar cells. However, they are also significantly less efficient. Now, an international team has succeeded in reducing losses in the lower contact layer of tin perovskite solar cells: The scienstists identified chemical compounds that self-assemble into a molecular layer that fits very well with the lattice structure of tin perovskites. On this monolayer, tin perovskite with excellent optoelectronic quality can be grown, which increases the performance of the solar cell.
