28% Efficiency For Oxford PV Perovskite Cell

Oxford PV has achieved 28% power conversion efficiency for its perovskite solar cells, beating its previous record of 27.3% efficiency for a perovskite-silicon solar cell announced in June 2018 (see Oxford PV Reports 27.3% Perovskite Cell Efficiency).

It achieved the 28% efficiency record for a 1cm² perovskite-silicon tandem solar cell. The National Renewable Energy Laboratory (NREL) has certified the record.

“Today’s 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. The solar cells we are developing are not only efficient but also stable,” said Dr Chris Case, Chief Technology Officer at Oxford PV.

In August 2018, the German Ministry of Economic Affairs and Energy gave green light for a €2.8 million ($3.24 million) grant to support research on perovskite solar cell technology for high volume manufacturing (see Oxford PV Led Consortium Gets German Grant).

Frank P. Averdung, CEO of the British technology company, said that Oxford PV’s pilot line is routinely producing commercial sized tandem solar cells for validation by its unnamed development partner, who is only identified as 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 the commercial phase,” claimed Averdung.
