Oxford Photovoltaics has reported a new perovskite tandem solar cell record, certified by Fraunhofer ISE at a conversion efficiency of 27.3%. Oxford PV's latest record for a 1 cm2 perovskite-silicon tandem solar, reportedly exceeds the 26.7% efficiency world record for a single-junction silicon solar cell.
Oxford PV recently produced a 1 cm2 perovskite-silicon two-terminal tandem solar cell with a verified conversion efficiency of 25.2%, through an ongoing collaboration with Helmholtz-Zentrum Berlin (HZB) and the Photovoltaics and Optoelectronics Device Group at the University of Oxford, led by Professor Snaith.
Oxford PV is currently scaling its perovskite-silicon solar cell technology from the lab to high-volume manufacturing capability as it bids to licence the technology to mainstream PV cell manufacturers.
The company is producing commercial sized 156 mm x 156 mm perovskite-silicon solar cells, at its 17,000 m2 industrial pilot line in Germany.
Dr Chris Case, Chief Technology Officer at Oxford PV added, 'We are continuing to push our perovskite-silicon solar cell technology with a roadmap that extends beyond 30% efficiency, driving the world towards an all-electric future. Oxford PV counts on the support of development partners, suppliers and customers to deliver its perovskite solar technology.'
