GCL Technology has unveiled plans to list its perovskite subsidiary, GCL Optoelectronic, in Hong Kong in 2026, as part of a broader strategy to expand internationally and advance next-generation solar technologies, including space-based applications.

Chairman Zhu Gongshan said the company is accelerating its transition away from reliance on a single business line. Its future portfolio will focus on granular silicon, perovskite technologies, and battery materials such as anodes and cathodes. He identified perovskite as a central driver of the company’s long-term transformation.

According to Fan Bin, GCL Optoelectronic is targeting 2 GW of production capacity, with 1 GW already operational. The company expects shipments to reach approximately 100 MW in 2026.

Fan added that overseas expansion plans are taking shape, with the possibility of establishing a 500 MW perovskite production line in the United States under consideration, contingent on the success of the planned IPO. Zhu noted that preparations for the Hong Kong listing are progressing, and if completed, the move could position GCL Optoelectronic as the first publicly listed company focused specifically on perovskite technology.

Beyond terrestrial markets, GCL also outlined an ambitious three-phase roadmap for space-based solar development. The first phase involves deep-space durability testing in 2026, followed by mass production of specialized space modules between 2027 and 2028. The final phase envisions supplying power systems for Chinese spacecraft.

The company confirmed that initial samples were sent for testing in the first quarter to the Shanghai Institute of Space Power-Sources, part of the China Aerospace Science and Technology Corporation. GCL is also collaborating with Shanghai SastSpace on perovskite solar wing development and in-orbit applications.

As part of its validation efforts, GCL plans to conduct a near-space test mission using a high-altitude balloon in the fourth quarter of 2026. The company aims to demonstrate that its perovskite technology can withstand extreme temperature ranges—from approximately -90°C to 110°C—far exceeding typical terrestrial conditions.

Fan said GCL is targeting a service life of more than five years for its perovskite products in space. Initial launch validation missions could begin as early as July 2026, with two to three missions planned within the year.
