Key Takeaways
  • Oxford PV has started commercial delivery of its tandem solar modules  

  • The 1st shipment has been directed to an unidentified customer in the US  

  • Produced in Brandenburg, it will allocate production to other applications and customers in the near future 

Perovskite solar cell technology specialist Oxford PV has released the 1st shipment of its perovskite-on-silicon tandem solar modules to a customer in the US. The University of Oxford spin-off claims these modules have a 24.5% module efficiency. 

Oxford PV believes this marks the 1st commercial deployment of a perovskite tandem solar panel globally. These perovskite tandem solar panels incorporate a 72-cell arrangement, with capacity to produce up to 20% more energy than a standard silicon solar panel, it claims. 

The unidentified US customer will use these panels in a utility-scale installation which will enable the developer to reduce the levelized cost of electricity (LCOE). Oxford PV adds that these will ensure more efficient land use by generating more electricity from the same area. 

“The commercialisation of this technology is a breakthrough for the energy industry. High-efficiency technologies are the future of the solar industry, and that future is starting now,” said Oxford PV CEO David Ward.  

Produced at the company’s MW-scale pilot production line in Brandenburg an der Havel, Germany, Oxford PV said it plans to allocate production towards additional utility customers, specialty products, and pilot residential applications in the coming months. It also targets to scale production to the GW level at a future high-volume manufacturing site.  

In June 2024, Oxford PV achieved 26.9% efficiency for a 60-cell residential size double-glass tandem module with a designated area of over 1.6 m². It launched the same at the recently concluded Intersolar Europe 2024 (see Perovskite Specialist Expands Tandem Cell Based Module Portfolio).
