Reports suggest that China-based GCL (via its new subsidiary Kunshan GCL Photoelectric Materials) has achieved a photoelectric conversion efficiency of 19.04% on a 1,000mm x 2,000mm single-junction perovskite solar module. The result was reportedly officially tested by the China National Institute of Metrology to confirm the results.
The GCL Perovskite team stated it is "delighted to have achieved its goal of surpassing the expected conversion efficiency of 19% for standard-sized perovskite modules, having previously achieved 18.04% conversion efficiency for a single-junction perovskite solar module in November 2023". And the team is one step closer to its efficiency target of 26% for a 2m² (1,000mm × 2,000mm) single-junction perovskite solar module, while focusing on research and development for the next generation of tandem perovskite modules.
