The €2.8m project includes thin film equipment maker Von Ardenne, research institute Helmholtz-Zentrum Berlin, the Fraunhofer Institute for Solar Energy Systems and the Technical University of Berlin and is backed by the German Ministry of Economic Affairs and Energy.
The project will focus on preparing perovskite solar cell technology for high volume manufacturing, including the optimisation of the perovskite-silicon tandem solar cell architecture on industrial 156 mm x 156 mm wafer formats. The project will also look at the refinement of industrial scale process technology and life-cycle analysis of tandem solar cells.
“The German Government’s investment recognises the opportunity perovskite solar technology has to dramatically enhance the performance of solar energy generation," said Frank Averdung, Chief Executive Officer at Oxford PV. "Oxford PV has made substantial progress in scaling and preparing its technology for high volume manufacturing. With commercial sized tandem cells already in production at our pilot line – it is now a matter of further optimising the process, in preparation for commercial deployment.”
Last month Oxford PV achieved a world record certified efficiency of 27.3% for its perovskite solar cell. This exceeded the 26.7% efficiency world record for a single junction silicon solar cell - validating the ability of perovskite to be used as the upper layer of a tandem cell based on a silicon substrate. Oxford PV’s perovskite-silicon solar cell technology roadmap extends beyond 30% efficiency, and the company is setting up a volume manufacturing plant in Germany.
