A highly-weldable high-efficiency photovoltaic welding strip comprises a conductive base strip (1). The conductive base strip (1) is made of metal elementary substances or alloy materials and has an upper wide surface and a lower wide surface. A plurality of groove assemblies (2) is distributed on at least one wide surface of the conductive base strip (1). Each groove assembly (2) is composed of a plurality of continuous grooves (3). Coupling platforms (4) are left between different groove assemblies (2). The height of the coupling platforms (4) is not smaller than the highest point of the grooves (3), and the diameter of the maximum inscribed circle of the coupling platforms (4) is not smaller than 0.1 mm. According to the welding strip, the coupling platforms of a certain area are left between the groove assemblies (2) on the surface, and therefore, requirements of a binding force of the welding strip and a battery sheet can be satisfied, and the proportion of the area of the grooves (3) to the area of the welding strip can be increased maximally, and the power of a whole battery component can be improved. |
