AbolishedSolar-grade polycrystalline silicon
太阳能级多晶硅
Application Summary AI generated
GB/T 25074-2017 specifies the technical requirements, test methods, inspection rules, and packaging for solar-grade polycrystalline silicon used in photovoltaic applications. It is applied by manufacturers and testing laboratories to ensure the purity, resistivity, carbon and metal impurity levels, and minority carrier lifetime of polysilicon feedstock for solar cell production. This standard is critical for quality control in the upstream solar material supply chain, particularly for ingot casting and wafer slicing processes in China's photovoltaic industry.
