<p><P>PROBLEM TO BE SOLVED: To provide a solar cell element whose workability is improved while keeping the connection strength between conventional solar cell elements, and a solar cell module using it. <P>SOLUTION: In the solar cell element, a surface electrode is formed in one major surface side of a semiconductor substrate 1 with a semiconductor junction part, and a back electrode consisting of a collector 5 by a first metal and an output part 6 by a second metal whose solder wettability is better than that of the first metal is formed in the other major surface side. A projection part 13 is provided on the output part 6. <P>COPYRIGHT: (C)2004,JPO</p> |
