Oxford PV has announced a new record for solar panel efficiency. Oxford's silicon-perovskite tandem module, developed in collaboration with the Fraunhofer Institute for Solar Energy Systems, achieved a record conversion efficiency of 25%, a significant increase over the 24% efficiency of most conventional modules.

Oxford PV, a division of the University of Oxford in England, is working to produce silicon-perovskite tandem solar cells with a theoretical efficiency of more than 43%, with less than 30% silicon in solar cells. .
"Our record-breaking solar panels demonstrate that we are on the cutting edge of the next solar revolution, based in part on our tandem cell technology," said Chris Case, Chief Technology Officer, Oxford PV. "Solar power is one of the most efficient and sustainable energy sources today. Our continued technological advances will continue to improve the efficiency of panels, generate more electricity from the same area, and expand their use in all market sectors, from residential to commercial to utility."
Oxford PV is expanding its production in Germany this year, eventually allowing mass production of tandem solar cells.
David Ward, chief executive of Oxford PV, said: "This new world record is a huge milestone for Oxford PV and confirms that our solar cells on the back can deliver record performance when assembled into solar cells." This is the first step in the transformation in 2024, when we begin delivering market-ready modules from our factory in Germany and continue to search for a new large-scale manufacturing facility that will allow us to introduce our technology globally. the wider public".
The Oxford silicon perovskite solar PV cell delivers 421W of power in an area of 1.68m² . For the production process, the researchers used modular TEC devices from Fraunhofer ISE that were already in mass production and adapted processes for tandem technology. In order to provide accurate and repeatable information about the performance of the tandem module, the layers of perovskite and silicon cells generating electricity in natural sunlight were illuminated with as many different LED light sources as possible.
