Supplying multiple leading lithium battery enterprises

Leader in Perovskite Photovoltaic Technology

Independently developed large-size perovskite photovoltaic modules, comprehensively leading the industry in module size, conversion efficiency, stability, and industrialization.
In June 2025, commercial perovskite modules successfully passed the 3-times intensified aging test by an international authoritative institution, becoming the world's first case.
In December 2025, the steady-state conversion efficiency of 2㎡ tandem modules broke through 27.06%, currently the world's largest area and highest conversion efficiency commercial perovskite module.
In June 2025, the world's first GW-level perovskite industry base officially commenced production and operation.
In October, the first full-size 2400mm×1200mm perovskite module rolled off the GW-level production line.

Leveraging the abundant solar resources in Qinghai Province, collaborating with Huaneng Clean Energy Technology Research Institute, Kunshan GCL Photoelectric, and numerous national-level research institutes and universities to conduct perovskite photovoltaic module demonstrations under high-altitude and strong ultraviolet conditions on the Qinghai-Tibet Plateau. Continuous technological breakthroughs and process adjustments have been carried out, achieving the development of core equipment for square-meter level perovskite mass production lines, completing the upstream and downstream entire industry chain upgrade of perovskite modules from materials to process equipment. The localization rate of core equipment has reached over 90%, perovskite module size has reached 1 meter x 2 meters, and module conversion efficiency continues to set new records.

Since 2023, China Huaneng has built and put into operation the world's first 5MW commercial-level perovskite photovoltaic demonstration base in Gonghe Photovoltaic Park, Qinghai Province, with GCL Photoelectric supplying 3MW of 1x2 meter perovskite single-junction modules. In August 2025, this marked the transition of China's perovskite photovoltaic technology from the laboratory stage to large-scale demonstration applications. Currently, the project operates stably, with perovskite showing excellent performance in weak light conditions and superior data performance in hot extreme environments, significantly higher than traditional crystalline silicon modules.
