GRECO kick-off in Madrid: advancing photovoltaics through “open science”
Participants from partner institutions at the GRECO kick off in Madrid on 25. June 2018.
The Helmholtz-Zentrum Berlin (HZB) is one of ten international partners in the GRECO pilot project funded under the European Union framework programme Horizon 2020. They intend to jointly test OpenScience approaches for exchanging knowledge and research data in order to accelerate the development of innovative PV products worldwide. GRECO will receive three million euros in funding through 2021.
The kick-off meeting took place in Madrid end of June 2018. The Institute for Solar Energy at the Universidad Politécnica de Madrid (UPM) is coordinating the research project that will see industry organisations, companies, government, academia and scientific organisations working together.
HZB contributions: materials data base and videotutorials
Dr. Eva Unger and her Helmholtz Young Investigator Group at the HZB are participants in GRECO: “We are contributing our expertise in the field of perovskite absorber layers for tandem photovoltaics and intend to establish a materials database in which key parameters and data from various absorbers can be brought together and made available in an open manner”, explains the chemist. She is also planning a video tutorial on the measurement and characterisation of solar cells. “Characteristic current-voltage curves are often not informative enough for determining the efficiency of perovskite solar cells”, explains the PV expert. The video is intended to contribute to establishing uniform quality standards for measuring solar cells worldwide.
Transparency and innovative products
Through use of Open Science Tools such as Open Access, Open Data, Open Education, Open Notebooks, Open Software, and Open Peer Review, GRECO wants to create complete transparency and exchange in the conduct of research. “This will enable new scientific concepts to be quickly applied by third parties, accelerating progress”, commented coordinators Dr. Ana B. Cristóbal and Prof. Carlos del Cañizo of the Universidad Politécnica de Madrid.
Innovative products to be developed by GRECO include repair and recycling methods for solar modules, precise modelling of power yields over timescales of decades (ageing), solar-powered irrigation systems, innovative solar modules as well as PV heat pump systems for use in various areas of everyday life.
Scientific Partners: Universidad Politécnica de Madrid, Pompeu Fabra University, Universidad de Évora, Central Solar Energy Laboratory of the Bulgarian Academy of Sciences, Helmholtz-Zentrum Berlin, Reiner Lemoine Institute, and Universidade de São Paulo
Industrial partners: Insolight SA (Switzerland) and the Euro-Mediterrean Irrigators Association (Spain)
In addition, the project is receiving support from the region of Andalusia, Spain.

- BESSY II: Heterostructures for SpintronicsSpintronic devices work with spin textures caused by quantum-physical interactions. A Spanish-German collaboration has now studied graphene-cobalt-iridium heterostructures at BESSY II. The results show how two desired quantum-physical effects reinforce each other in these heterostructures. This could lead to new spintronic devices based on these materials.
- Green hydrogen: MXenes shows talent as catalyst for oxygen evolutionThe MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalised, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the best metal oxide catalysts currently available. The team is now extensively characterising these MXene catalysts for water splitting at the Berlin X-ray source BESSY II and Soleil Synchrotron in France.
- SpinMagIC: 'EPR on a chip' ensures quality of olive oil and beerThe first sign of spoilage in many food products is the formation of free radicals, which reduces the shelf-life and the overall quality of the food. Until now, the detection of these molecules has been very costly for the food companies. Researchers at HZB and the University of Stuttgart have developed a portable, small and inexpensive 'EPR on a chip' sensor that can detect free radicals even at very low concentrations. They are now working to set up a spin-off company, supported by the EXIST research transfer programme of the German Federal Ministry of Economics and Climate Protection. The EPRoC sensor will initially be used in the production of olive oil and beer to ensure the quality of these products.
