With the collaboration agreement closed in March 2019, Meyer Burger and Oxford PV agreed on an exclusive partnership to jointly develop the required technology for mass production of perovskite tandem cells based on Meyer Burger’s heterojunction silicon cell technology (HJT) as well as necessary novel perovskite production equipment from Meyer Burger. Meyer Burger is the largest single shareholder of Oxford PV with a share of 19.76%.

Meyer Burger’s assessment was and is that the perovskite tandem technology will only reach the required technology and process maturity, product reliability and cost structure for competitive mass production in a few years. Any consequences of Oxford PV’s announcement therefore have no impact on the success of Meyer Burger’s transformation nor on Meyer Burger’s communicated guidance.

The perovskite tandem technology is an integral part of Meyer Burger’s technology roadmap. Based on its own developments and know-how, Meyer Burger has a comprehensive portfolio of processes, technologies and production techniques for its own potential mass production of tandem solar cells and modules. This includes the essential manufacturing processes and machines for perovskite tandem solar cells and corresponding solar modules with Meyer Burger’s proprietary SmartWire interconnection technology. Meyer Burger thus holds a key to critical success factors such as product reliability and cost-efficient mass production.
