FBR颗粒硅，是一种粒状形态的多晶硅。经过10余年自主研发，协鑫成为全球唯一能够实现大规模产业化生产FBR颗粒硅的企业。目前，协鑫FBR颗粒硅产能达42万吨，制造基地位于四川、江苏、内蒙古。
FBR颗粒硅具有品质更优、成本更低、碳排放更低、能耗更低等优势，其金属杂质水平全行业领先，驱动行业标准大幅提升。较改良西门子法棒状硅，FBR颗粒硅综合电耗降低77%，人力成本降低57%，水消耗降低27%，氢消耗降低57%。
同时，协鑫FBR颗粒硅已获中、法碳足迹权威认证，其碳足迹在其领域中全球最低，每公斤FBR颗粒硅CO2排放量37kg，单环节碳足迹下降约75%。此外，较棒状硅，生产每万吨FBR颗粒硅对应节省约4.32亿度电。
● CCz技术（对应展品：硅棒，FBR+CCz模型）
CCz 技术，即连续直拉单晶硅技术。与RCz（重复装料拉晶技术）相比，协鑫CCz技术优势明显。1)自动化程度高：CCz可减少人工加料环节，降低人工成本和外界环境杂质引入的干扰。2)产量更高：CCz单台拉晶炉单产可达到180kg/天。3)品质更优：CCz拉晶和加料融化同时进行，拉制单晶电阻率均一，适配N型电池片高要求。
FBR颗粒硅的高流动性与CCz技术完美适配高效电池片，未来将全面赋能光伏产业链效率提升及品质优化。
● 单晶硅片
单晶硅片是硅棒经过切断、切方、倒角、切片、清洗等工艺制成。协鑫硅片产能稳居行业前列，目前公司硅片产能达58.5GW。
协鑫单晶硅片满足182或210尺寸市场主流需求，兼容整片、半片电池设计。同时，协鑫单晶硅片电性能表现优异，可用于TOPCon、HJT、IBC等高效电池工艺。
● 电池片
根据技术路线不同，电池可分为P型和N型， N型TOPCon（隧穿氧化层钝化接触）电池已成为主流产品，还有HJT（异质结）电池，BC电池等产品。
协鑫以TOPCon电池为主，多种技术路线并行。协鑫集成芜湖基地20GW高效N型TOPCon电池片，制造项目（一期10GW）已正式实现全面达产，单日产量超400万片，量产效率26.2%以上，良率超98%，达到行业TOPCon电池效率第一梯队的领先水平。
Here, we will see GCL's comprehensive layout and involvement in the silicon energy sector.
● Industrial silicon powder
High-purity polysilicon produced from industrial silicon powder through a series of production processes is an important raw material for the PV and semiconductor industries.
GCL uses high-quality silicon ore as the raw material and low-ash coal as the reductant to produce high-purity industrial silicon through high-temperature redox reactions, and then grinds the industrial silicon into industrial silicon powder.
● FBR (Fluidized Bed Reactor) granular silicon
Granular silicon is grain-shaped polysilicon.
Through more than a decade of independent research and development, GCL has become the world's only company to produce granular silicon on a large scale.
Currently, GCL's manufacturing bases in Jiangsu, Sichuan, and Inner Mongolia can manufacture 420,000 tons of FBR granular silicon.
FBR granular silicon is superior in quality, with lower cost, carbon emissions, and energy consumption as well as an industry-leading metal impurity level, significantly improving industry standards.
Compared to rod silicon production by the improved Siemens process, the production of FBR granular silicon reduces the overall power consumption by 76%, labor costs by 61%, water consumption by 18%, and hydrogen consumption by 57%.
Additionally, GCL's FBR granular silicon has been certified by the Chinese and French authorities to boast the lowest carbon footprint in its field globally, with CO2 emissions of 37kg per kilogram, reducing the carbon footprint per production stage by approximately 75%.
Furthermore, compared to rod silicon, every 10,000 tons of FBR granular silicon produced saves approximately 432 million kWh of electricity.
● CCz technology (exhibits: silicon rods, granular silicon, and integrated CCz application model)
CCz refers to continuous Czochralski technology.
Compared to RCz (Recharged Czochralski), GCL's CCz technology has the following advantages.
1. High degree of automation: With CCz, the manual feeding step can be eliminated, lowering labor costs and minimizing interference from external environmental impurities.
2. Higher yield: The capacity is up to 180 kg/day per CCz furnace.
3. Superior quality: CCz crystal pulling and material feeding & melting can be implemented simultaneously to ensure uniform monocrystalline resistivity, meeting the high requirements of N-type solar cells.
The combination of highly fluid FBR granular silicon and the CCz technology perfectly meets the requirements of efficient solar cells, which will comprehensively empower the PV industry chain for efficiency enhancement and quality optimization.
● Monocrystalline silicon wafer
Monocrystalline silicon rods are made into silicon wafers through processes such as cutting, squaring, chamfering, slicing, and washing.
Currently, GCL's industry-leading silicon wafer capacity reaches up to 58.5 GW.
GCL's monocrystalline silicon wafers are available in mainstream sizes of 182 mm and 210 mm and are compatible with both full-cell and half-cell designs.
In addition, they are suitable for efficient cell technologies such as TOPcon, HJT, and IBC due to their excellent electrical performance.
● PV Cell
According to the different technical route, the battery can be divided into P type and N type, N type TOPcon (tunneling oxide passivation contact) battery has become the mainstream product, as well as HJT (heterojunction) battery, BC battery and other products.
GCL focuses on TOPcon batteries while pursuing multiple technical routes at the same time. GCL integrated 20GW high-efficiency N-type TOPcon battery cells in Wuhu Base, with a 20GW capacity for high-efficiency N-type TOPcon cells (first phase at 10GW), has officially achieved full production capacity, with a daily output of more than 4 million pieces, mass production efficiency of more than 26.2%, and yield of more than 98%, reaching the leading level of TOPcon battery efficiency in the industry
