Oxford PV sees record 28 percent perovskite efficiency
Oxford PV has certified a world record for a perovskite-based tandem solar cell.

The 1 cm 2 perovskite-silicon tandem solar cell has achieved a 28% conversion efficiency, certified by the National Renewable Energy Laboratory. The achievement edges out Oxford PV’s own previous certified record of 27.3% efficiency for its perovskite-silicon solar cell, announced earlier this year. 

“The record demonstrates the unprecedented pace of our technology development. We are continuing to push our perovskite-silicon solar cell technology, with a roadmap that extends beyond 30% efficiency," said Dr Chris Case, Chief Technology Officer at Oxford PV." The solar cells we are developing are not only efficient but also stable. Similar devices from our research and development facility have passed at least 2000 hours of damp heat reliability testing, in line with IEC 61215 protocol.”

“2018 has been a significant year for Oxford PV," said Frank Averdung, CEO at Oxford PV. "Alongside the pace of our technology advancements in both efficiency and stability, our pilot line is routinely producing commercial sized tandem solar cells for validation by our development partner – a major manufacturer of silicon solar cells and modules.  With new collaborations with key industry players strengthening our manufacturing capabilities, the foundations are in place, to move perovskite photovoltaics into commercial phase.”
