China Huaneng’s Clean Energy Technology Research Institute and the Qinghai unit of China Huaneng Group have commissioned what they describe as the world’s first commercial scale 5 MW Perovskite PV demonstration and verifies in the Gonghe Photovoltaic Park in the province of Qinghai.
The facility, formally brought online on August 23, 2025, aims to generate empirical data on electricity performance, long-term reliability and the adaptability of the environment of perovskiet and tandem perovskiet/silicon modules under extreme plateau conditions.
The system integrates large perovskiet modules from domestic manufacturers, aimed at more than 90% domestic content for core equipment. Test protocols follow the TÜV Süd-improved IEC 61215 sequence (DH2000/TC400) adopted by Utmolight technology: 2,000 hours of exposure to moist heating, 400 thermal cycles and post test power degradation under 5%. The program simulates cumulative ultraviolet radiation at high height (104 kWh/m²) and assess combined light-and-heating at 1.2 × standard irradiation (1,200 W/m²) and 60 C.
Huaneng’s Laboratory Scales Perovskiet/silicon tandem cells will also become a member of the program. According to Huaneng, the modules have exceeded 33% conversion efficiency, with laserrand-loss under 0.1 mm and encapsulants with watervapor transmissions speeds under 10⁻⁶ g/m²/day, supported by pilot production and demonstration labels lab and commercial work flows. Important participants include GCL -Opto -Electronic Material, Micrquanta, Utmolight technology and Renshine Solar. The Institute of Physics, the Chinese Academy of Sciences, supports material sciences, especially with precursor purity and control density control.
Huaneng estimates the current perovskiet module mass production costs at CNY 0.8 ($ 0.11)/W and a highland level of electricity near CNY 0.15/kWh. It aims to increase the efficiency of module above 22% and to lower the mass production costs under CNY 0.6/W by 2026 to approach parity with crystalline silicon.
The company fits the site and both a technical milestone and a standard platform. They are leading efforts to develop the Perovskite module-test standards, the recording of UV, sand-bodies and printing factors at high altitudes and a “demonstration base plus data service” model with a subscription fee on the Proefpen. Project vessels say that the site will accelerate the location of the domestic supply chain and inform applications about the buildings-integrated photovoltaic (BIPV), floating and mobile photovoltaic.
Although the demonstration marks a step towards commercialization, Huaneng said that long -term and further upscaling data will be needed to validate sustainability and cost courses before perovskiet modules can be used on a large scale than demonstration projects.
