<p><P>PROBLEM TO BE SOLVED: To obtain a solar battery cell preventing an occurrence of a bulge and a protrusion of an aluminum electrode to achieve a good process yield, and to obtain its manufacturing method. <P>SOLUTION: The solar battery cell has: a p-type polycrystalline Si substrate 1; an n-type diffusion layer 2 formed on a light-receiving surface of the p-type polycrystalline Si substrate 1; a surface side electrode 7 provided on the n-type diffusion layer 2; and an aluminum electrode 5 and a silver electrode 16 provided on the surface layer of the surface opposite to the light-receiving surface of the p-type polycrystalline Si substrate 1. An Si oxide film 4 is interposed between the aluminum electrode 5 and a silver electrode 16, and the p-type polycrystalline Si substrate 1, and is heat treated. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
