FBR granular silicon, an innovative “black technology” product with independent intellectual property rights developed by GCL, has obtained 136 authorized patents, including 3 national standards and 4 international standards.

FBR granular silicon demonstrates numerous advantages, including low cost, low energy consumption, low emissions, long lifespan, and high quality with exceptional conversion efficiency. Its production energy consumption is only one-fourth that of rod-shaped polycrystalline silicon, leading to an approximate 85% reduction in carbon footprint. This achievement has earned GCL the prestigious dual certification of carbon footprint authority from China and France. Additionally, FBR Granular Silicon has received validation and recognition from top-tier corporate clients.

GCL has strategically established manufacturing bases for FBR granular silicon in Jiangsu, Sichuan, Inner Mongolia, and overseas locations. These facilities collectively boast a production capacity of 400,000 tons.

• Saving the time of feeding and material preparation process in the recycling loop
• 20% increase in production of crystal furnace
• The length of single silicon rod is not controlled by crucible
• The resulting monocrystalline silicon rods exhibit a more uniform resistivity and narrower distribution, amplifying their overall quality.
• Increase in the individual furnace charging capacity
• The quality of monocrystalline silicon rods is stable
• A significant increase in the production efficiency and level of automation
• The requirement of efficient N-type cells is satisfied.
• The adoption of CCz technology on FBR granular silicon in the future

Surrounding the implementation of granular silicon, downstream application scenarios, and industrial ecology, GCL is diligently researching and breaking through key technologies such as "CCz+granular silicon application+N-type+large-size waferization." The resulting monocrystalline silicon wafers can meet the demand for sizes of 182 or 210, accommodating both full-cell and half-cell solar panel designs. They are compatible with various advanced cell technologies such as TOPcon, HJT, and IBC. The silicon wafer production capacity has reached an impressive 55GW.

With the advent of the N-type era in the PV industry, the value of n-type cell technologies such as TOPCon (Tunnel Oxide Passivated Contact) and HJT (Heterojunction) cells has become increasingly prominent. Leveraging its leading expertise in N-type cell production, GCL is advancing the construction of a 20GW high-efficiency TOPCon photovoltaic cell project. On July 28, 2023, they achieved mass production and delivery of large-sized high-efficiency N-type solar cell modules.

GCL's 60 gigawatts high-efficiency module intelligent manufacturing facility embraces a fully automated production system and intelligent management approach. It is compatible with large-sized modules, specifically those sized 210mm downwards. The product portfolio primarily focuses on large-sized, high-performance P-type and N-type modules, offering superior weak light power generation performance and an enhanced temperature coefficient to optimize electricity production. By 2023, GCL's production capacity for large-sized modules is expected to approach approximately 30 gigawatts.

• The large-sized N-type TOPCon single-glass and double-glass modules, measuring 210mm and 182mm respectively, have successfully obtained TUV Rheinland certification.

• The large-sized PERC series high-efficiency modules, measuring 210mm and 182mm respectively, have been awarded the carbon footprint certification by France.

GCL Optoelectronic Materials Ltd. has independently developed large-sized perovskite photovoltaic (PV) modules, establishing the world's largest production line for 100 MW perovskite modules with the highest module efficiency certification. It has emerged as the exclusive global enterprise to obtain commercial certification for practical perovskite module products. Leveraging the core technology and industrial advantages of perovskite cells, GCL Photovoltaics has received investments and support from leading entities such as Temasek Holdings, Sequoia Capital China, IDG China, and Tencent.
