Oxford PV and Meyer Burger enter strategic partnership

Oxford Photovoltaics and Meyer Burger Technology have entered into a strategic partnership and signed an exclusive cooperation agreement to jointly accelerate the development of mass production technology for perovskite on silicon heterojunction (HJT) tandem solar cells.

Meyer Burger and Oxford PV agreed to combine Meyer Burger's leading HJT and SmartWire Connection technology with Oxford PV's perovskite solar cell technology. Meyer Burger will sell a 200 MW HJT line for the pilot production of tandem cells that will be ramped up by the end of 2020 in Oxford PV's Brandenburg an der Havel facility. The initial tandem solar cell efficiency target for the 200 MW pilot production line will be 27%. The characteristics of Meyer Burger's HJT cells make them the perfect bottom cells for Oxford PV's perovskite top cell layers.

Meyer Burger will also develop equipment to industrialize the mass production of the respective perovskite layers that are deposited onto HJT bottom cells. The companies say that this further accelerates the time-to-market and enlarges Oxford PV's and Meyer Burger's advantage as perovskite and HJT technology leaders in the global solar industry.

To underscore this strategic partnership, Meyer Burger will take a stake in Oxford PV of up to 18.8% of capital through the issue of up to 62.29 million new Meyer Burger registered shares from the company's existing authorized capital, making Meyer Burger the largest shareholder of Oxford PV.

Oxford PV's perovskite tandem solar cells use bottom cells of crystalline silicon and have achieved a certified world-record efficiency of 28% in 2018. Such tandem devices use the higher energy blue part of the solar spectrum more effectively, allowing a theoretical efficiency limit of 43% compared to 29% for traditional single-junction silicon-based solar cells.
