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.

- 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.
- Metallic nanocatalysts: what really happens during catalysisUsing a combination of spectromicroscopy at BESSY II and microscopic analyses at DESY's NanoLab, a team has gained new insights into the chemical behaviour of nanocatalysts during catalysis. The nanoparticles consisted of a platinum core with a rhodium shell. This configuration allows a better understanding of structural changes in, for example, rhodium-platinum catalysts for emission control. The results show that under typical catalytic conditions, some of the rhodium in the shell can diffuse into the interior of the nanoparticles. However, most of it remains on the surface and oxidises. This process is strongly dependent on the surface orientation of the nanoparticle facets.
