The dopant is used to change the impurities and resistivity of silicon ingot to meet the requirements. Henergysolar offers various types of boron dopant & phosphorus dopant:

■Shape:
    ■Ingot
    ■Chunk
    ■Wafer
■ Doped type:
    ■ P-type 
    ■ N-type
■Resistivity :
    ■0.001-0.006 ohm.CM 
    ■Resistivity deviation 0.001 or 0.0005 in the concentration range
■ Boron (atom/cm3) = 1.1732E20 ~ 1.6184E19
■ Phosphorus (atom/cm3) = 7.3763E19 ~ 9.6552E18
■ Carbon content (atom/cm3) <5E16
