The quality of the conductive paste has an effect on the conversion efficiency of solar cells and stability. The latest research progress of silver paste at home and abroad is reviewed. And it mainly focus on the effects of components on the performance of positive silver conductive paste for solar cells,and average particle size in 1 micron of the spherical silver powders and low ratio of flake silver powder preparation and the impact on the electrical conductive silver paste, lead-free glass powder preparation and influencing factors of properties, and the preparation status of levels volatile organic carrier. Finally the developing direction of conductive silver paste is prospected, and the method of preparation of high disper- sion spherical silver powders is put forward, and the performance requirements and developing direction of solar cell conductive paste with glass melt and organic carrier are pointed out.
