Kunshan GCL Optoelectronic Materials Co. , Ltd., a subsidiary of GCL Tech, was established in 2010 and focuses on the R&D and mass production of large-area perovskite photovoltaic modules. The company's core R&D team began developing perovskite technology in 2013 and has since led the industry in module size, conversion efficiency, stability, and mass production progress. In June 2025, the company's commercial perovskite modules passed the authoritative 3× stricter accelerated aging tests, making it the first perovskite enterprise globally to achieve this milestone. The same month, GCL Photovoltaic’s GW-scale perovskite production base in Kunshan commenced operations, marking the official entry of perovskite photovoltaic technology into a new era of global commercial-scale production.
