PURPOSE:To enable solar cells to be easily connected together by a method wherein both electrodes are provided to one side of the solar cell. CONSTITUTION:A cone-shaped through-hole 11 is provided to a silicon substrate 1 penetrating it through, and a P-N junction 3 is formed on these surfaces. An insulating film 4 is formed on the other side of the silicon substrate 1 around the through-hole 11, and one of electrodes is provided covering the surface of the P-N junction 3 from one side. The other electrode is provided to the other side of the substrate 1 in another part. |
