HZB participates in a new consortium for Perovskite solar technology that is led by Oxford PV Germany GmbH. The consortium is funded by the German Ministry of Economics and Energy with 2.8 Million Euros and aims to further demonstrate the manufacturability of perovskite-silicon tandem solar cells.

Further partners are Von Ardenne GmbH, Fraunhofer-Institute for Solar Energy Systems ISE, and the Technical University of Berlin. The project will focus on preparing perovskite solar cell technology for high volume manufacturing. This will include the optimisation of the perovskite-silicon tandem solar cell architecture, to make further efficiency improvements on industrial 156 mm x 156 mm wafer formats; the refinement of industrial scale process technology; and life-cycle analysis to inform the social-environmental impact of the tandem solar cells.

"Perovskite-based tandem solar cells are very promising to achieve really high efficiencies. In order to contribute to this exciting development we have built up strong competences in perovskites and tandem cell technology such as the Helmholtz Innovation Lab HySPRINT", says Prof. Dr. Rutger Schlatmann, Director of the Competence Center Thin Film and Nanotechnology for Photovoltaics Berlin (PVcomB) at HZB. "To the consortium with Oxford PV, we contribute our vast expertise in high-efficiency silicon heterojunction bottom cells", adds Dr. Bernd Stannowski who is leading these activities at the PVcomB.

Dr. Chris Case, Chief Technology Officer at Oxford PV says “The consortium partners bring together the perfect balance of expertise. Refining the manufacturing process of our perovskite solar cell technology will ensure the highest performing tandem solar cell in the field and the easy transfer of our technology into silicon solar cell and module production lines.”

 In June 2018, HZB and Oxford achieved an independently certified efficiency of 25.2 % for their perovskite silicon tandem solar cell. “In our cooperation, we aim to further optimize perovskite silicon tandem cells, demonstrate their scalability and facilitate their integration into large-area solar modules”, says Rutger Schlatmann.

    How carbonates influence CO2-to-fuel conversion
    Researchers from the Helmholtz Zentrum Berlin (HZB) and the Fritz Haber Institute of the Max Planck Society (FHI) have uncovered how carbonate molecules affect the conversion of CO2 into valuable fuels on gold electrocatalysts. Their findings reveal key molecular mechanisms in CO2 electrocatalysis and hydrogen evolution, pointing to new strategies for improving energy efficiency and reaction selectivity.

    Peat as a sustainable precursor for fuel cell catalyst materials
    Iron-nitrogen-carbon catalysts have the potential to replace the more expensive platinum catalysts currently used in fuel cells. This is shown by a study conducted by researchers from the Helmholtz-Zentrum Berlin (HZB), Physikalisch-Technische Bundesanstalt (PTB) and universities in Tartu and Tallinn, Estonia. At BESSY II, the team observed the formation of complex microstructures within various samples. They then analysed which structural parameters were particularly important for fostering the preferred electrochemical reactions. The raw material for such catalysts is well decomposed peat.
