Oxford PV unveils residential solar module with record-setting 26.9% efficiency

Oxford PV has announced a record-setting 26.9% efficiency for its double-glass, 60-cell “residential sized” perovskite tandem module at the Intersolar Europe 2024 event. The module reportedly has a surface area of a little over 1.6 m square meters (1m x 1.7m) and weighs a little under 25 kg, “the ideal size for residential applications,” according to Oxford PV.

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.


The record-setting module's efficiency result was certified by the Fraunhofer CalLab. 

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."

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.” 

Oxford PV 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.
