May I ask what kinds of tests need to be carried out after producing polysilicon? What test reports does the customer need?

Generally, these include resistivity of the base phosphorus and base boron, minority carrier lifetime, oxygen and carbon concentrations, and the content of the matrix metal. Please refer to Solar-grade Polycrystalline Silicon GBT25074-2010
