| Abstract: | The superfine spherical silver powder was prepared by chemical reduction method, with uniform grain size, high dispersed, and particle size of 1--2μm The effect of silver powder preparation factors was studied. Based on the silver powder and the appropriate components, the back electrode paste for amorphous silicon photovoltaic battery was prepared. The preparation process was improved, and the preparation steps decreased. Having been printed and sintered, the capability of silver electrode, such as the welding strength, resistivity and the complex with aluminium electrode, was tested. The re- sult showed that the silver paste achieve industrial production application requirements. |
