Oxford PV, a global pioneer in next-generation solar technology, has achieved a new world record in solar module efficiency. The 60-cell residential-size module, produced with the company’s perovskite-on-silicon tandem solar cells, has achieved an unprecedented efficiency of 26.9%, surpassing the current best silicon modules ~25% with a similar designated module area.
The breakthrough double-glass module, with a designated area just over 1.6 square metres, weighs under 25kg and is an ideal size for residential applications. The efficiency was independently measured and certified by the Fraunhofer CalLab. Oxford PV produces the proprietary high efficiency tandem solar cells at its manufacturing facility in Brandenburg an der Havel, Germany, and uses both in-house and contract services for the module assembly.
Speeding up the decarbonisation journey
David Ward, CEO of Oxford PV, commented: “Oxford PV’s record-setting module represents a significant advancement for solar power generation. Homeowners along with commercial and utility customers will all benefit from upwards of 20% more power with the same footprint. Not only does this save installation costs, it also speeds up the decarbonisation journey and can contribute to the global energy transition in a meaningful way.”
Vision of an all-electric future
Chris Case, CTO at Oxford PV, added, “This achievement comes on the heels of our previous efficiency of 25% on an industrial-size module, reported in January 2024. For the past decade, the team has continued to demonstrate the potential for perovskite on silicon tandem solar cells, setting and breaking efficiency records along the way. Now, we are taking the next steps to bring this high-efficiency solar technology into commercial use to support our vision of an all-electric future.”
