Oxford PV Debuts Residential Solar Module with Record 26.9% Efficiency

Oxford PV has achieved a new world record in solar module efficiency. The 60-cell residential-size module, produced with Oxford PV’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 m2, weighs under 25 kg and is an ideal size for residential applications. The efficiency was independently measured and certified by the Fraunhofer CalLab.

“Oxford PV’s record-setting module represents a significant advancement for solar power generation,” said David Ward, CEO of Oxford PV. “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 decarbonization journey and can contribute to the global energy transition in a meaningful way.”

“This achievement comes on the heels of our previous efficiency of 25% on an industrial-size module, reported in January 2024,” added Chris Case, CTO at Oxford PV. “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.”

Oxford PV will exhibit its solar technology at Intersolar Europe (Munich) June 19-21, 2024. The company plans to scale up its manufacturing of tandem solar cells to gigawatt volumes within the next few years, to address the multi-terawatt market needs.
