Utmolight has achieved 18.1% efficiency with its Perovskiet PV modules, according to the results confirmed by the US National Renewable Energy Laboratory (NREL).
Utmolight said that his 0.72 m² Perovskiet PV panel has achieved a stabilized full efficiency of 18.1%or 130.5 W based on testing by NREL.
The module also showed more than 950 seconds zero demolition under maximum Power Point Tracking (MPPT) conditions, which determines a new global efficiency record for perovskiet modules of this size, according to the company.
Utmolight produced the tested module with the help of a scalable, mass production process in its 150 MW pilot line, which has delivered Perovskiet modules to commercial projects in Chinese provinces such as Anhui, Jiangdong, Guangdong and Hebei.
It claimed that only mass -producable, stable, highly efficient perovskiet modules yield real customer value.
The company has focused on the deliverability of the product and earned IEC 61215/61730 certification for stability in November 2023 with a module efficiency of 13.2% (95 W). It said that it is planning to increase the certified efficiency to 16.7% (120 W) by November 2024, and claims the highly efficient perovskiet module in the world to pass IEC stability tests.
The recent leap to 18.1% efficiency came from the tweaks of the production line cutting film defect speeds, fine tuning parameters and upgrading equipment components to increase the yield.
In November 2024, the first Utmolight production line found the first Gigawatt scale in Wuxi, Jiangsu, full integration of the process. The initial 2.8 m² Perovskiet module of De Lijn delivered 450 W with a full efficiency of 16.1%. Because adult pilot line processes shifts to large-scale output, Utmolight focuses on a mass production efficiency of 20% in 2025.
