HZB experts present cooperation opportunities at Intersolar Europe in Munich
Tandem solar cells combining silicon and perovskite layers could convert up to 30 percent energy into electricity.
How do environmental influences influence the performance of solar modules? The Competence Center for Photovoltaics (PVcomB) is investigating this question at the outdoor test stand.
The international exhibition “Intersolar” brings photovoltaic research and the solar industry together. It is a perfect opportunity for researchers from Helmholtz-Zentrum Berlin to present thin-film photovoltaic technologies and projects, including for example perovskite solar cells and tandem solar cells.
Intersolar Europe(22 to 22 June) is one of the most important international events for the solar industry, where manufacturers, suppliers, distributors and service providers come to learn of new developments in the solar industry. A team from Helmholtz-Zentrum Berlin (HZB) will be there, in Hall A2, Booth 572, to show which topics HZB is researching in the field of renewable energies. Important points of contact for industry are the Helmholtz Innovation Lab HySPRINT and the Competence Centre Thin-Film and Nanotechnology for Photovoltaics Berlin (PVcomB). These two institutes promote technology transfer and will be there to answer questions at the exhibition.
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 572 (A2.572). The exhibition will take place from 20 to 22 June 2018 in Munich

- Green hydrogen: A cage structured material transforms into a performant catalystClathrates are characterised by a complex cage structure that provides space for guest ions too. Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced performance. Measurements at BESSY II showed that the clathrates undergo structural changes during the catalytic reaction: the three-dimensional cage structure decays into ultra-thin nanosheets that allow maximum contact with active catalytic centres. The study has been published in the journal ‘Angewandte Chemie’.
- An elegant method for the detection of single spins using photovoltageDiamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.
- Solar cells on moon glass for a future base on the moonFuture settlements on the moon will need energy, which could be supplied by photovoltaics. However, launching material into space is expensive – transporting one kilogram to the moon costs one million euros. But there are also resources on the moon that can be used. A research team led by Dr. Felix Lang of the University of Potsdam and Dr. Stefan Linke of the Technical University of Berlin have now produced the required glass from ‘moon dust’ (regolith) and coated it with perovskite. This could save up to 99 percent of the weight needed to produce PV modules on the moon. The team tested the radiation tolerance of the solar cells at the proton accelerator of the HZB.
