Oxford PV debuts 26.9% efficient residential module
Oxford PV, has achieved 26.9 solar efficiency with a 60-cell residential-size module, produced with the company's perovskite-on-silicon tandem solar cells. The record-breaking efficiency surpasses the current best silicon modules ~25 percent with a similar designated module area.
The double-glass module, with a designated area just over 1.6 m2, weighs under 25 kg. 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.
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 percent 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 percent 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 will exhibit its solar technology at Intersolar Europe (Munich) 19 – 21 June 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.
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
