<p><P>PROBLEM TO BE SOLVED: To provide a solar cell superior in the yield wherein the occurrence of blister and protrusion in a back electrode is prevented, and to provide a method of manufacturing the same. <P>SOLUTION: The solar cell includes a silicon substrate 13 comprising a first conductive type layer, a second conductive type layer 15 formed on a light receiving surface of the silicon substrate 13, a light receiving surface side electrode 21 provided on the second conductive type layer 15, and a back electrode 27 provided on the backside opposite to the light receiving surface of the silicon substrate 13. The back electrode 27 includes a first back electrode 29 provided on the backside with an aluminum as a main component, and a second back electrode 31 which contains one or more kinds of metal selected from a group containing silver, copper, gold and nickel, and is provided on the entire surface of the first back electrode 29. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
