<p><P>PROBLEM TO BE SOLVED: To solve the problem that when the output deriving portion of a solar battery element and its each collector portion are so superimposed partially on each other and are so subjected to a screen printing as to bake them and form an electrode, the cell-crack of the solar battery element which starts from their superimposed portion has been generated conventionally. <P>SOLUTION: In a semiconductor substrate 1 of the solar battery element, different conductive regions from each other are so formed on its one principal-surface side and its other principal-surface side as to form respectively a front-surface electrode 4 and rear-surface electrodes 5, 6 on its one and other principal-surface sides. The rear-surface electrodes 5, 6 containing a glass frit comprise a strip-like output deriving portion 5 formed on the other principal-surface side and collector portions 6 formed in the nearly whole region of the other principal-surface side wherefrom the formed region of the output deriving portion 5 is excluded. Further, in this solar battery element, each collector portion 6 is so provided as to superimposed it on the peripheral edge portion of the output deriving portion 5, and the glass-frit content of this superimposed portion 5a of the output deriving portion 5 by each collector portion 6 is made smaller than the one of a region 5b of the output deriving portion wherefrom the superimposed portion 5a is excluded. <P>COPYRIGHT: (C)2004,JPO</p> |
