Oxford PV is developing and commercializing thin-film perovskite solar cells, which can be printed directly onto silicon solar cells, CIGS solar cells or glass. Pioneering work developing perovskite thin-film solar cells has delivered a route to boosting the efficiency of current commercial cells; using a high efficiency coating in a multi-junction or “tandem” cell architecture. In addition, printing perovskites directly onto glass has led to a semi-transparent coating ideal for BIPV applications and, once integrated into the glazing units of a building, the technology is capable of providing a significant percentage of the building’s electrical energy requirements directly from sunlight.
By employing well known and well understood printing processes, focused on inexpensive and abundant raw materials, Oxford PV has developed a highly cost effective technology.
The company has exclusively licensed the rapidly growing portfolio of fundamental intellectual property developed by its academic team.
Oxford PV has acquired the former thin-film production site of Bosch Solar in Germany, to establish a fab with pilot-scale capacity for perovskite wafers. To that end, the Company also received funding of €15 million form the European Investment Bank (EIB), to support the commercialization of its perovskite-on-silicon tandem solar cell technology. In June 2018, Oxford PV reported a new perovskite tandem solar cell record, certified by Fraunhofer ISE at a conversion efficiency of 27.3%. Oxford PV’s latest record for a 1 cm2 perovskite-silicon tandem solar, reportedly exceeds the former 26.7% efficiency world record for a single-junction silicon solar cell.

Meyer Burger is considering legal options to enforce its rights after Oxford PV announces unilateral termination of the collaboration
Earlier this month, Oxford PV announced the completion of the build-out of its manufacturing site in Brandenburg an der Havel, Germany. Oxford PV concluded that announcement by saying that "With the achievement of this factory milestone, Oxford PV has terminated its exclusive relationship with Meyer Burger".
Meyer Burger Technology was informed of the termination of partnership (in place since 2019) through the press release (as well as a letter from Oxford Photovoltaics). In view of the unexpected announcement of termination by Oxford PV, Meyer Burger is reportedly considering legal options to enforce its rights.
Oxford PV has announced that it has completed the build-out of its manufacturing site in Brandenburg an der Havel, Germany.
The site houses the world’s first volume manufacturing line for Oxford PV’s innovative perovskite-on-silicon tandem solar cells with an annual target manufacturing capacity of 100 MW. Oxford PV expects the line to start full production in 2022.
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.”
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."
