[0002] A solar cell module is composed of high-efficiency crystalline silicon solar cells, ultra-white embossed tempered glass, EVA, a transparent TPT backplane, and an aluminum alloy frame, and has the characteristics of long service life and strong mechanical compressive external force. There are multiple groups of solar cells inside the solar panel. The welding rod can be directly welded on the silicon crystal to connect the solar cells in the solar panel to each other. Therefore, the welding tape can also be called an interconnection bar. The interconnection bar transports the current generated by the solar cells to the photovoltaic bus bar. The photovoltaic bus bar is a hot-dip tin-coated copper conductor installed on the periphery of the solar panel. The photovoltaic bus bar connects the interconnection bar to the junction box. The photovoltaic welding tape is an important component of each mainstream solar panel and is an important factor in improving the efficiency and durability of the solar panel. Only by correctly installing high-quality photovoltaic welding rods on the solar panel can the high efficiency and durability of the solar panel be achieved.

[0003] The resistance of the welding tape is mainly determined by the size and specifications of the welding tape itself and the material of the copper substrate. The composition of the tin coating on the surface will not have an obvious impact on the resistance of the welding rod. Increasing the width or thickness of the welding tape can reduce the resistance of the welding tape. Therefore, we propose a solar cell module using a special-shaped welding tape to improve the above problems. Content of the Utility Model
