Oxford PV reaches world-record solar cell efficiency through perovskites

by admin

Oxford PV As independently certified by Fraunhofer ISE, the new world record efficiency for commercial size M4 solar cells is a staggering 28.6%.

The cell was made by depositing a thin film of perovskite on a conventional silicon solar cell. Combined tandem solar cells achieve significantly higher conversion efficiencies than the average 22-24% of mainstream silicon-only solar cells.

The solar cells were produced on Oxford PV’s integrated production line in Brandenburg an der Havel, Germany. The plant has started initial production of the company’s tandem solar cells for integration by solar module manufacturing partners, and is ramping up production to mass production. The facility, which has been in operation since 2017, houses the world’s first mass production line for perovskite-on-silicon tandem solar cells and employs over 70 staff.

“Our latest efficiency achievement of 28.6% is more than 1.5% higher than the record we achieved last year and exceeds our own roadmap plan of 1% annual increase,” said Chris, Chief Technology Officer at Oxford PV. Mr Case said. “These record-breaking solar cells are manufactured on the same production line as our commercial solar cells with 27% efficiency and already meet stringent performance and reliability targets.”

David Ward, Chief Executive Officer of Oxford PV commented: This achievement demonstrates our strong intellectual property and is a testament to the talent and commitment of our team. While we continue to innovate perovskite-on-silicon technology in small research size solar cells, our primary focus is on improving commercial size cells for the market, scaling up production and We work with our solar module partners to prepare the solar panels for assembly. Our team has made great strides in his 2023, bringing the revolutionary solar cell closer to the hands of our module manufacturing customers. “

Oxford PV, a spin-out from the University of Oxford, is developing research-size cell-based perovskite-on-silicon technology at its R&D center in Oxford, UK. The company’s production facility near Berlin, Germany, is focused on scaling up and continuously improving the manufacturing of commercial-sized devices, and the company recently registered a subsidiary in the United States.
