Oxford PV sets record solar panel efficiency of 25 per cent

Oxford PV’s technology combines a thin layer of perovskite, a synthetic solar conversion material, with mainstream silicon solar cells to create more powerful solar panels that can generate around 20 per cent more electricity than silicon-only cell technology.

The latest Oxford PV solar panel was produced in partnership with Germany’s Fraunhofer Institute for Solar Energy Systems. Using the Institute’s Module-TEC (Technology Evaluation Centre), the Oxford team optimised the existing production line for its tandem technology, producing a silicon perovskite tandem solar panel that delivered an output of 421W on an area of 1.68m². Oxford PV claims the 25 per cent efficiency achieved makes it the world’s ‘most efficient perovskite silicon tandem solar module in industrial format’.

“Our record-breaking solar panels demonstrate that we are on the cusp of the next solar revolution, which will be delivered, in part, by our tandem cell technology,” Chris Case, chief technology officer at Oxford PV said in a statement.
