Abstract:
To improve adhesiveness with tabs of lead (Pb) free solder to solar cell elements using resin hardening type silver paste for a collector electrode.
Between a surface member and a rear member, two or more solar cell elements 1 are arranged. In the solar cell module which connects the collectors of solar cell elements 1 electrically and mutually with tabs 12, the collectors of the solar cell elements 1 consist of silver paste mixed with silver powder and heat hardening resin.
