Taiyangneng said its 1.4GW TOPCon project has entered trial production and will provide high-efficiency cells for module upgrades, with external sales possible. Its small-area perovskite/silicon tandem cells have exceeded 34% conversion efficiency. Construction of a 10MW perovskite–silicon tandem pilot line has begun and is expected to be fully operational by end-2026; the company says the pilot line will accelerate conversion of the technology into mass-production products.
