Oxford PV has overwhelmed its personal world document for photo voltaic module effectivity, after its new The 60-cell residential-size module achieved an unprecedented conversion charge of 26.9 p.c.
According to the Oxford University spin-out, the module made with Oxford PV’s perovskite-on-silicon tandem photo voltaic cells surpassed present effectivity information by about 25 p.c, reaching an analogous vary of module earlier this yr.
The document was independently measured and authorized by the acknowledged calibration laboratory Fraunhofer CalLab.
The firm’s breakthrough double-glass module, with a hard and fast space of greater than 1.6 sq. meters, weighs lower than 25kg and is designed for residential functions at Oxford PV’s manufacturing facility in Brandenburg an der Havel, Germany.
“Oxford PV’s record-setting module represents a big advance for solar energy era,” stated David Ward, CEO of Oxford PV. “Home house owners together with business and utility prospects will all profit from as much as 20 p.c extra energy with the identical footprint.
“This not solely saves set up prices, it additionally accelerates the decarbonization journey and might contribute to the world’s power transition in a significant manner.”
Perovskite-on-silicon photo voltaic cells are a brand new PV know-how that claims to have greater effectivity potential than established silicon photo voltaic cells.
Oxford PV beforehand predicted that perovskite-on-silicon tandem photo voltaic cells would have a theoretical most effectivity of greater than 43 p.c, in comparison with lower than 30 p.c for silicon photo voltaic cells.
The firm claims that it has a transparent roadmap to take the know-how past 30 p.c effectivity and plans to extend tandem photo voltaic cell manufacturing to gigawatt volumes within the subsequent few years.
“This achievement comes on the heels of our earlier effectivity of 25 p.c in an industrial-sized module, reported in January 2024,” stated Chris Case, Oxford PV’s chief know-how officer. “Over the previous decade, the group has continued to reveal the potential for perovskite in silicon tandem photo voltaic cells, setting and breaking effectivity information alongside the way in which.
“Now, we’re taking the following steps to carry this high-efficiency photo voltaic know-how to business use to assist our imaginative and prescient of an all-electric future.”
