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.

- Five Berlin-based research institutions join forces in data-driven materials researchResearch data is regarded as key to materials research in the age of artificial intelligence (AI). Five Berlin-based research institutions have now signed a Memorandum of Understanding (MoU) to establish long-term collaboration in the fields of research data, data infrastructures and AI.
- 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.
- New contact material boosts the efficiency of perovskite solar cellsA newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several advantages over the standard material C60, as shown by the study led by Steve Albrecht’s team. The new material has since been patented and is already commercially available.
