<p><P>PROBLEM TO BE SOLVED: To provide an electrode wire for a solar cell which is easily and plastically deformed by thermal stress generated in a semiconductor substrate and prevents the substrate from being damaged by the thermal stress, and to provide a method of manufacturing the same. <P>SOLUTION: The wire for solar battery is provided with a band-plate-like core material 2, and melted solder plating layers 3A and 3B covered on the surface of the core material 2. The core material 2 is 2.3μΩcm or less in average volume resistivity and 19.6 MPa or more and 85 MPa or less in average yield strength, and recesses 4 are repeatedly formed on at least one surface of the core material 2 along the widthwise direction of the core material in the lengthwise direction at a space P. The width D of the recess 4 is preferably 1/600 or more of the average spacing P and 3/4 or less of the thickness t of the core material 2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
