FBR Granular Silicon

GCL has independently developed FBR granular silicon technology since 2011, successfully developed an innovative product with independent intellectual property rights - FBR granular silicon, and successfully entered the "systematic, standardized, digital, integrated, intelligent, modular" replicable production era.

Currently, GCL has established granular silicon production bases in Jiangsu, Sichuan, Inner Mongolia and other places, with an annual FBR granular silicon production capacity of 420,000 tons. Compared with traditional rod-shaped silicon, FBR granular silicon shows significant energy consumption advantages, and comprehensive power consumption, labor costs, water consumption, hydrogen consumption and other indicators are significantly reduced. At the same time, granular silicon has won high recognition from the industry for its better fluidity, lower cost, more stable quality and superior carbon footprint. It has won dual carbon footprint certifications in the field of photovoltaic raw materials from China and France, and is recognized globally. The lowest carbon footprint in the industry, opening up a new era of photovoltaic material revolution and low-carbon application.

CCz Techonology

  • Saving the time of feeding and mixing in the cycle
  • The length of a single silicon rod is not controlled by the crucible
  • The feeding amount of a single furnace is increased
  • The production efficiency and automation level are significantly improved
  • The use of CCz technology with granular silicon in the future
  • The output of crystal furnace is increased by 15-20%
  • The resistivity of the produced single crystal silicon rod is more uniform and the distribution is narrower
  • The quality of single crystal rod is stable
  • The requirement of efficient N-type cells is satisfied

Silicon Wafer

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 58.5GW.

Cell

With the advent of the n-type photovoltaic era, the value of N-type cell technologies such as TOPCon (tunneling oxide passivation contact) cell and HJT (heterojunction) cells has become more prominent. GCL relies on its leading N-type cell technology to promote the construction of a 20GW high-efficiency TOPCon photovoltaic cell project and achieve mass production and delivery of N-type high-efficiency large-size cells on July 28, 2023.

Module

GCL's 60GW high-efficiency module intelligent manufacturing base adopts fully automatic production and intelligent management, and is compatible with large-size modules from 210mm down. The products mainly focus on large-size high-efficiency n-type modules, with better weak light power generation performance and temperature coefficient to improve power generation. As of now, GCL's n-type photovoltaic module production capacity is nearly 30GW.

• The 210mm and 182mm large-size n-type TOPCon single-glass and double-glass modules have passed TÜV Rheinland certification

• The 210mm and 182mm large-size PERC series high-efficiency modules have obtained the French carbon footprint certification

Perovskite

Perovskite is called the third generation or a truly disruptive new concept solar cell. It uses the principle of photoelectric effect to make solar cells using perovskite-type organic metal halide semiconductors as light-absorbing materials.

Perovskite components

GCL-Poly has independently developed large-size perovskite photovoltaic cell modules, built the world's largest 100MW perovskite module mass production line with the highest module efficiency certification, and became the world's first company to obtain commercial certification for practical perovskite modules. With the core technology and industrial advantages of perovskite cells, GCL-Poly has received support from Temasek Investment, Sequoia Capital, IDG China, Tencent, etc.
