The invention discloses conductive glass powder and a preparation method thereof, conductive paste and a preparation method and application thereof, and belongs to the technical field of electronic materials. The glass powder A and the glass powder B are prepared, the glass powder A can reduce compounding of a metallized area, and the glass powder B can reduce the contact resistivity of the conductive paste and a passivation layer substrate; the glass powder A and the glass powder B are compounded for use, and the mass ratio of the glass powder A to the glass powder B is adjusted to prepare the conductive paste, so that the conductive paste has a relatively wide sintering window, and has good contact performance and metal compounding during high-temperature and medium-low-temperature sintering; and meanwhile, the contact performance of the conductive paste on the single-layer passivation layer and the laminated passivation layer can be reduced. 本发明公开了一种导电玻璃粉及其制备方法、导电浆料及其制备方法与应用，属于电子材料技术领域。本发明通过制备出玻璃粉A和玻璃粉B，玻璃
