Oxford PV, the leader in the field of perov­skite solar cells, announced in December 2018 a new, certified, world record for its perov­skite based solar cell. Oxford PV’s one square centi­meter 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 last year.

Chris Case, chief tech­nology officer at Oxford PV commented, “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. Similar devices from our research and develop­ment facility have passed at least two thousand hours of damp heat relia­bility testing, in line with IEC 61215 protocol.”

Frank Averdung, chief exe­cutive officer at Oxford PV added, “2018 has been a signi­ficant year for 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.” (Source: Oxford PV)
