    • A photovoltaic device that can prevent performance degradation caused by electrodeposition generated as a result of moisture penetration. In the photovoltaic device, two or more intermediate insulation portions that electrically insulate solar cell unit cells positioned adjacently in the X-direction are formed on the substrate center side of side insulation portions so as to extend in the Y-direction in a parallel arrangement across the X-direction, a conductive portion that electrically connects solar cell unit cells positioned adjacently in the X-direction is provided in a position partway along each of the intermediate insulation portions, and the solar cell unit cells where the conductive portion is positioned are electrically insulated from a solar cell unit cell positioned adjacently in the X-direction by another of the intermediate insulation portions positioned distant from the conductive portion in the X-direction.

    • A solar panel has a substrate (1) and a plurality of photovoltaic cells (5). The substrate (1) has a first side (1a), a second side (1b), a third side (1c) and a fourth side (1d). The plurality of photovoltaic cells (5) are provided on the substrate (1), arranged parallel to the first side (1a), and connected in series one after another. The plurality of photovoltaic cells (5) have a first trench (15a) located adjacent to the first side (1a) and parallel to the first side (1a) and a second trench (15b) located adjacent to the second side (1b) and parallel to the second side (1b), while do not have a trench located adjacent to the third side (1c) and parallel to the third side (1c) and a trench located adjacent to the fourth side (1d) and parallel to the fourth side (1d). The first trench (15a) and the second trench (15b) are formed from a surface of the plurality of photovoltaic cells (5) toward a surface of the substrate (1), and so extend to vicinities of the third side (1c) and the fourth side (1d) as not to reach an edge of the substrate (1).
    • 太阳能电池板具有基板(1)和多个光伏电池(5)。 基板(1)具有第一侧(1a),第二侧(1b),第三侧(1c)和第四侧(1d)。 多个光伏电池(5)设置在与第一侧(1a)平行布置的基板(1)上,并联连接。 多个光伏电池(5)具有与第一侧(1a)相邻且平行于第一侧(1a)的第一沟槽(15a)和位于第二侧(1b)附近的第二沟槽(15b),以及 平行于第二侧(1b),而不具有位于第三侧(1c)附近并且平行于第三侧(1c)的沟槽和位于第四侧(1d)附近并平行于第四侧 侧(1d)。 第一沟槽15a和第二沟槽15b由多个光电池(5)的表面朝向衬底(1)的表面形成,并且延伸到第三侧(1c)的附近和 第四侧(1d)不到达基板(1)的边缘。
