<p><P>PROBLEM TO BE SOLVED: To provide a solar cell of high performance capable of maintaining low contact resistance even with thinner electrodes. <P>SOLUTION: The solar cell includes a first conductive type silicon substrate 1, a diffusion layer 2 of the conductive type opposite to the first one which is formed on a light receiving surface side of the silicon substrate 1, a light receiving surface electrode 7 which is electrically connected to the diffusion layer 2, a diffusion layer 3 of the conductive type identical to the first one formed on the rear surface side of the first conductive type silicon substrate 1, and a rear surface electrode 7 which is electrically connected to the diffusion layer 3. A dielectric film 4 is so formed not to contact to the diffusion layer 2 of the conductive type opposite to the first one arranged directly under the light receiving surface side electrode. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
