Oxford Photovoltaics Limited (Oxford PV) was founded in 2010 as a spin-out from the University of Oxford to commercialize a new technology for thin-film solar cells. It was amongst the first in the world to recognize the potential of perovskites to act as a low-cost, highly efficient solar cell absorber material to convert sunlight into electricity.

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.

Oxford PV receives a €2.8 million grant to prepare perovskite-silicon solar cell production for high volume manufacture

Oxford Photovoltaics (PV) has been awarded a €2.8 million grant from the German Ministry of Economic Affairs and Energy to prepare perovskite-silicon solar cells for high-volume manufacturing. The technology consortium is by headed by Oxford PV and includes specialist PV equipment manufacturer VON ARDENNE and three German institutes, Fraunhofer Institute for Solar Energy Systems, Helmholtz-Zentrum Berlin (HZB) and the Technical University of Berlin.

The newly funded project focuses on the optimization of the perovskite-silicon tandem solar cell architecture, to make further efficiency improvements on industrial 156 mm x 156 mm wafer formats. Importantly, this will include the refinement of industrial scale process technology as well as life-cycle analysis on the social-environmental impact of such cells.

Dr Chris Case, Chief Technology Officer at Oxford PV commented, “The unique, optically enhanced architecture developed as part of this collaboration, minimizes losses, and has helped us achieve this record setting efficiency”.

EU establishes the MAESTRO project - a €4 million program for perovskite solar materials research

The European Commission has established a new research training network, led by the University of Bath, to make perovskites "truly exploitable" and make perovskite-based devices commercially viable. The new program, called MAESTRO, has been given €4 million in funding and has begun hiring researchers to gain new knowledge and provide innovation in the exploitation of perovskite materials.

A trans-European project, MAESTRO is an inter-sectoral and multidisciplinary network of 10 academic and seven industrial partners from nine EU and EU-Associated countries: the UK, Italy, Spain, Greece, Germany, Poland, Lithuania, Israel and Switzerland.

Oxford PV moves headquarters and perovskite solar R&D to new site

Oxford PV has announced it has moved its UK-based headquarters and R&D facilities to a new location in Oxford, UK. The new site consolidates and strengthens Oxford PV’s UK-based perovskite photovoltaic research and development activities, by providing a larger, controlled laboratory environment, with ample space for expansion of its equipment and expertise in the future.

Oxford PV’s experienced research and development team at the site will continue to focus on advancing its perovskite photovoltaic technology. Additionally, Oxford PV’s UK team will continue to support the transfer of its advanced lab based perovskite on silicon tandem solar cell technology to industrial scale processes and equipment, an activity that takes place at the company’s pilot line, in Brandenburg an der Havel, Germany, in close collaboration with its joint development partner – a major manufacturer of silicon solar cells and modules.
