    • The method of lap-welding of metal plates using a laser beam, wherein at least one of the metal plates is surface-treated, includes putting a metal plate on the other metal plate and forming a gap between the metal plates so that gas generated at the treated surface at the time weld can be dissipated therethrough. A surface-treated first work and a surface-treated second work are placed one on the other and clamped by means of a clamp with an opening of the clamp centered at the location on the first work to be welded. Then a laser beam is directed to the location to form a weld. The beam is then directed near the inner periphery of the opening to form a heated portion so that the heated portion deflects to form a gap through which the gas generated at the treated surface dissipates thereby reducing gas pressure.
    • 使用激光束对金属板进行搭接焊接的方法,其中至少一个金属板进行表面处理,包括将金属板放置在另一金属板上并在金属板之间形成间隙,使得在 在时间焊接处理的表面可以从其中消散。 表面处理的第一工件和经表面处理的第二工件一个放置在另一个上并且通过夹具夹紧,夹具的开口以第一待焊接工件的位置为中心。 然后将激光束导向该位置以形成焊缝。 然后将梁引导到开口的内周边附近以形成加热部分,使得加热部分偏转以形成间隙,在处理的表面处产生的气体通过该间隙消散,由此降低气体压力。

    • A solar battery module (40) is constituted by a stack of: a plurality of solar battery strings (30) and bus sections (32) connected to both ends of each of the plurality of solar battery strings (30); flexible resin layers (33a through 33c); and a flexible resin film (34). The flexible resin layers (33a through 33c) and the flexible resin film (34) have, on a light receiving surface side of solar battery cells (20), holes through which the bus sections (32) are each partially exposed. The exposed parts of the bus sections (32) serve as a respective plurality of electrically-connecting means (32a). A solar battery array (41) is constituted by a plurality of solar battery modules (40). The plurality of solar battery modules (40) are electrically connected with each other via the plurality of electrically-connecting means (32a). This makes it possible to achieve a large-scale solar battery array (41) with high mechanical strength.
    • 太阳能电池模块(40)由多个太阳能电池串(30)和连接到多个太阳能电池串(30)的两端的总线部分(32)的堆叠构成; 柔性树脂层(33a至33c); 和柔性树脂膜(34)。 柔性树脂层(33a〜33c)和柔性树脂膜(34)在太阳能电池单体(20)的受光面侧具有各自部分地露出母线部(32)的孔。 总线部分(32)的暴露部分用作相应的多个电连接装置(32a)。 太阳能电池阵列(41)由多个太阳能电池模块(40)构成。 多个太阳能电池模块(40)经由多个电连接装置(32a)彼此电连接。 这使得可以实现具有高机械强度的大规模太阳能电池阵列(41)。
