Paste for solar cell electrode and solar cell

Abstract

In a paste for a solar cell light-receiving surface electrode including silver particles, glass frit, resin binder, and thinner, silver particles with a specific surface of 0.20-0.60 m 2 /g are used as the silver particles. The silver particles are preferably included at 80 mass % or more to the total amount of silver particles being included in the paste.

1 . A conductive paste for a solar cell light-receiving surface electrode, comprising
 70-90 wt % silver particles wherein 80 mass % or more of the silver particles have specific surface area of 0.20-0.60 m 2 /g,   0.5-10.0 wt % of glass frit and   resin binder, all based upon the weight of the paste.   
     
     
         2 . The paste for a solar cell light-receiving electrode of  claim 1  wherein the average particle diameter of the silver particles is 0.1-14 um. 
     
     
         3 . The paste for a solar cell light-receiving electrode of  claim 1  wherein softening point of the glass frit is 450-550 C.
