Abstract By means of scanning electron microscope, XRD, particle size distribution, specific surface area, tap density and other detection methods, the silver powder commonly used for solar front silver paste and other common spherical silver powder were analyzed and compared. The results show that spherical silver powder for solar front silver paste is a kind of polycrystalline silver powder with good sphericity, concentrated particle size distribution and tap density of 5.71 g/cm3.
