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.

    BESSY II: Heterostructures for Spintronics
    Spintronic 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 evolution
    The 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.
