It was reported that UtmoLight reached 18.1% efficiency with its 0.72m² perovskite PV modules, according to results confirmed by the US National Renewable Energy Laboratory (NREL).
The module also showed over 950 seconds of zero degradation under maximum power point tracking (MPPT) conditions, setting a new global efficiency record for perovskite modules of this size, according to the company.
UtmoLight produced the tested module using a scalable, mass-production process at its 150 MW pilot line, which has supplied perovskite modules to commercial projects across Chinese provinces like Anhui, Jiangsu, Guangdong, and Hebei.
The company has focused on product deliverability, earning IEC 61215/61730 certification for stability in November 2023 with a module efficiency of 13.2% (95 W). The recent leap to 18.1% efficiency stemmed from production line tweaks – cutting film defect rates, fine-tuning process parameters, and upgrading equipment components to lift yield.
UtmoLight’s first gigawatt-scale production line in Wuxi, Jiangsu, is online and functioning. The initial 2.8m² perovskite module off the line delivered 450 W with a full-area efficiency of 16.1%. As it shifts mature pilot-line processes to large-scale output, UtmoLight targets a mass-production efficiency of 20% by 2025.
