The demand for conductive paste in the photovoltaic industry and electronic packaging field is undergoing a transformation from high silver content to low silver or even silver free. Although silver powder has excellent conductivity and chemical stability, it is expensive, has limited resources, and is prone to electromigration. In contrast, copper's conductivity is second only to silver and its c...
