The effect of silver powder properties on solar cell paste

As an effective substitute for traditional fossil energy,solar cells have attracted wide attention from scholars.As one of the main raw materials of crystalline silicon solar cells,the quality of silver paste affects the photoelectric conversion rate and the levelized cost of energy.Silver powder is the conductive phase in the paste,whose performance plays a key role in the electrical properties,fluidity and adhesion of the paste.In recent years,the research work in the field of silver powder finds that the shape,size,dispersion,particle size distribution and tap density of silver powder have an effect on the electrical properties of conductive paste.Studies have shown that silver powders with different shapes and particle sizes are the main factors determining the properties of paste conductivity and sintering quality.The tap density of the silver powder affects the compactness of the sintered thick film and the photoelectric conversion of the battery.In the preparation of silver powder,the selection of dispersants will affect the dispersibility of the silver powder,thereby affecting the fineness,adhesion and electrical resistivity of the paste.
