Oxford PV has reached a new efficiency world record for perovskite-silicon tandem cells at 29.52%, passing the previous record set less than a year ago by Helmholtz Zentrum Berlin. The new record has been certified by the U.S. National Renewable Energy Laboratory.

The new record was achieved on a cell measuring 1.12cm², produced in a laboratory setting. Oxford PV previously held the tandem cell efficiency record at 27.3%, and then 28%, before a group at Helmholtz Zentrum Berlin (HZB) pushed the record to 29.15% in January 2020. Both Oxford PV and HZB have stated that they have clear roadmaps to push this record beyond 30% in the near future.

Oxford PV, currently involved in building a manufacturing facility in Brandenburg an der Havel for its silicon perovskite tandem solar cells (in which it is investing around €44 million), has received €8.8 million funding from the state Ministry of Economics in Potsdam for this project.

'I am delighted that Oxford Photovoltaics has brought the solar technology developed by the company itself to market maturity and that it will soon start with industrial series production here in Brandenburg,' said Brandenburg Minister for Economic Affairs Jörg Steinbach. 'The decision by Oxford PV to expand the production facility in Hohenstücke is a clear commitment to our community.'

Oxford PV's Professor Henry Snaith recently stated that the Company's perovskite-based solar cells are scheduled to go on sale next year.

Professor Snaith said: "Perovskite PV has demonstrated its immense opportunity to transform solar energy generation... I am especially looking forward to the next 12 months and seeing our first commercial perovskite-silicon solar product on the market."

Oxford PV recently stated that it hopes to deliver perovskite-silicon tandem solar cells to high end solar module manufacturers in the first half of 2021, now less than a year away.

The group expects these solar cells to have an efficiency between 26-27%, to increase in efficiency by 1% per year as the company improves its manufacturing techniques. It was said that initially, a 400 watt 60-cell solar module will probably be available.

After ordering a 100 MW HJT production line from Meyer Burger in August 2019, Oxford PV has placed another partial order to expand the HJT line to an integrated 125 MW production line for high-efficiency perovskite HJT tandem cells.

The Swiss solar PV equipment manufacturer Meyer Burger Technology has received this partial order, worth CHF 18 million ($18.2 million).
