Silicon Energy

GCL is dedicated to driving the photovoltaic industry to become an indispensable co-builder of ecological value in the carbon-neutral system. Globally, GCL is constructing a silicon energy supply chain and establishing industry-leading intelligent production bases for silicon powder, FBR granular silicon, silicon wafers, cells, and modules. GCL provides efficient photovoltaic module products, "photovoltaic+" solutions, and smart operation and maintenance services to customers worldwide. Furthermore, GCL is steadily advancing the construction of new energy mega bases, promoting carbon reduction across the entire photovoltaic industry chain. In June 2023, GCL made the comprehensive decision to cease its production of rod-like silicon and withdraw from the field of photovoltaic rod silicon.

FBR Granular Silicon

GCL has successfully developed an innovative product with independent intellectual property rights—FBR granular silicon. This "cutting-edge technology" product features advantages such as low cost, low energy consumption, low emissions, long lifespan, high quality, and high conversion efficiency. The production energy consumption is only one-quarter that of traditional rod polysilicon. GCL TECH has established FBR granular silicon manufacturing bases in Jiangsu, Sichuan, and Inner Mongolia, with a production capacity of 420,000 tons (effective capacity reaching 340,000 tons). Products with <0.5ppbw total metallic Impurities of 5 elements accounting for >95%. Products with <1ppbw total metallic Impurities of 18 elements accounting for >75%. Products with turbidity of granular silicon ≤100NTU accounting for >90%.

CCz Techonology

  • 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

Silicon Wafers

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.

Cells

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.

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.

Perovskite

Perovskite is referred to as the third-generation or truly disruptive concept in solar cells. By harnessing the photovoltaic effect, solar cells are created using perovskite-type organic metal halide semiconductors as light-absorbing materials.

Perovskite Modules

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.
