Leading perovskite developer says latest conversion efficiency beats best single-junction silicon cell’s rate.Oxford PV, which brands itself as “The Perovskite Company” and is a leading player in the field of perovskite solar cells, has announced what it is calling “a certified new world record” for the solar-electronic conversion efficiency of its perovskite-based solar cell.
The company's 1 cm2 perovskite-silicon tandem solar cell has achieved a 27.3% conversion efficiency, certified by the Fraunhofer Institute for Solar Energy Systems ISE. This exceeds the 26.7% efficiency world record for a single-junction silicon solar cell.
Frank Averdung, Chief Executive Officer at Oxford PV commented, “This result further validates the ability of perovskite to enhance the performance of silicon based photovoltaics. Continuing to improve the performance of photovoltaics is fundamental for sustaining the growth of solar generated electricity.”
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.”
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, for validation by its development partner – a major manufacturer of silicon solar cells and modules.
Case added, “Today’s record demonstrates the considerable progress the company has made in driving its perovskite solar solution closer to commercialisation. We are in the process of scaling our perovskite-silicon solar cell technology from the lab to high volume manufacturing.
Established in 2010, as a spin-out from the University of Oxford, the company today has the largest team globally, exclusively focused on developing and commercialising perovskite based solar technology. Oxford PV has a research & development site in Oxford, UK and an industrial site in Brandenburg, Germany enabling the accelerated transfer of their technology to industrial scale solar cell production.
