GCL Optoelectronic Material
Listed on the Hong Kong Exchange in 2014, GCL Optoelectronic Material (GCL New Energy) is an energy company under the GCL Group. Its primary business is solar power generation, covering development, construction and operations. GCL New Energy focuses on both centralized and distributed PV power plants to provide the society with sustainable green energy that is clean, safe and efficient.
With 14 domestic regional subsidiaries, GCL New Energy operates across China, moreover, it has three regional subsidiaries in North America, Japan, and Africa, and established overseas representative offices in or dispatched developers to key overseas target markets.
While GCL's PV work is not solely focused on perovskites, it does have several directions of development having to do with perovskite materials and technologies. GCL representatives stated that the company’s lab has achieved a conversion efficiency of 16% on a large panel and are confident 18% could be achieved as well.
GCL said it has an experimental, 10 MW perovskite production line already in operation, which it intends to ramp up to 100 MW soon and following that with a 1GW fab.

Steric-complementary design pushes perovskite–silicon tandem efficiency to 32.3%
Researchers from Jiangsu University, Soochow University, Huaqiao University, GCL System Integration Technology, Chinese Academy of Sciences, The Hong Kong Polytechnic University and Suzhou Maxwell Technologies have reported a high-performance monolithic perovskite–silicon tandem solar cell featuring a steric-complementary interface design. The device achieved a certified efficiency of 32.12%, placing it among the most efficient tandem architectures reported to date and marking a significant advance toward the 40% efficiency threshold targeted for next-generation photovoltaics.
A persistent challenge in perovskite-silicon tandems is mitigating interfacial recombination without compromising either charge extraction or long-term stability. The team addressed this limitation through a Steric-Complementary Synergistic Strategy (SCSS) that fine-tunes the molecular-level interactions across the interface. This strategy employs a pair of size-mismatched cations - small, flexible piperazinium (PipI) and large, rigid phenethylammonium (PEAI) - that perform distinct yet complementary roles. While PipI penetrates deep into the perovskite surface to neutralize atomic-scale defects inaccessible to larger molecules, the bulky PEAI simultaneously assembles into a robust, hydrophobic canopy that shields the interface from environmental stress.
GCL Technology secures US$700 Million capital infusion
GCL Technology has secured a major investment - US$700 million from Infini Global Master Fund (finalized on November 7, 2025) - with the backing of international and Middle Eastern investors focused on technology.
The new funds will help GCL's push towards perovskite technology production and commercialization, and also its production ramp up of materials like polysilicon (used in solar panels) and silane gas (vital for chips and advanced solar cells).
GCL Perovskite launches its 1st large-size perovskite module
According to reports, GCL Perovskite, the perovskite manufacturing arm of GCL Group, has produced its first full-size perovskite module at its GW-scale production base. The module measures 2.76 m2 (2,400 × 1,150 mm), which the company claims is the largest mass-produced and commercialized perovskite module globally.
GCL Tech secures $700 million from Infini Capital
Earlier this month, Infini Capital made an investment in GCL through a strategic financing agreement. This investment involved a private placement raising of approximately USD 700 million (about HK$5.446 billion).
The funds will be primarily used to build a supply-side reform reserve, strengthen the company’s “second growth curve,” and optimize its capital structure.
GCL Optoelectronics raises US$28 million for perovskite PV factory
It was recently reported that GCL Optoelectronics Materials raised nearly CNY 200 million (almost USD$28 million) in a C2 financing round to advance perovskite solar manufacturing and research at its new gigawatt-scale facility in China’s Jiangsu province.
The round was co-led by China Cinda Asset Management and SAIF Partners, following the C1 round that included investors such as Goldstone Investment, Kunshan Gaoxin Group, Sequoia China, and Hanyang Capital. Lighthouse Capital continued to serve as the sole financial advisor.
