Patent ID: 7902451

Claim:
A solar cell including a plurality of photoelectric conversion elements, comprising: a transparent insulation substrate having a predetermined external profile, a prescribed layer formed on a main surface of said transparent insulation substrate for formation of a photoelectric conversion element, and a plurality of photoelectric conversion elements formed by delimiting said prescribed layer with a plurality of isolation line regions spaced apart from each other, extending in one direction, and exposing a surface of said transparent insulation substrate, and a plurality of connection line regions spaced apart from each other, extending in another direction crossing said one direction, wherein a string having said photoelectric conversion elements electrically connected in series by said connection line regions is formed at each of a plurality of regions located between said isolation line regions, an integrated string having one string electrically connected to a further string is formed in plurality by said string formed at each of a plurality of regions located between said isolation line regions, and a plurality of said integrated strings are electrically connected in parallel, wherein said transparent insulation substrate has an external profile of a triangle formed of a first outer edge, a second outer edge, and a third outer edge, each of said isolation line regions is arranged substantially parallel to said first outer edge, and each of said connection line regions is arranged substantially parallel to said second outer edge, the solar cell further comprising a plurality of additional connection line regions arranged substantially parallel to said third outer edge, and spaced apart from each other, such that each said photoelectric conversion element takes an external profile of a triangle, and wherein said isolation line region comprises a pair of regions to expose a surface of said transparent insulation substrate and having a region where said connection line region crosses said additional connection line region located between one and the other of said pair of regions.
