Abstract
A surface electrode () is installed on the light receiving surface of a solar cell element, the surface electrode () comprises three bus bar electrodes () for extracting light-produced at the solar cell element to the outside and collecting finger electrodes () connected to these bus bar electrodes (), and the bus bar electrodes () are not less than 0.5 mm and not more than 2 mm in width and the finger electrodes () are not less than 0.05 mm and not more than 0.1 mm in width. A high-efficient solar cell module can be obtained with substantially lowered resistance by increasing the number of bus bar electrode () and thereby decreasing the lengths of the finger electrodes ().
