UK-based Oxford PV made its first commercial perovskite-silicon tandem shipment in September 2024 (a US utility-scale project). Current commercial module efficiency is around 25%, with the company targeting 26% in 2026. Initial shipments are targeted at European premium residential installers at a price premium of approximately 35% over standard TOPCon. The company projects cost parity with TOPCon by 2028 as production scales.
