Pv ribbon, also known as tinned copper tape or tinned copper tape, is an important component of PV modules and is used to connect PV cells during PV cell packaging. It directs the electrical energy converted from light on silicon wafers to electrical devices and plays an important role in conducting and aggregating electrical energy to increase the output voltage and power of PV modules. Photovoltaic cells connected by photovoltaic tape photovoltaic modules are used directly in the construction of photovoltaic power systems.
The quality of the PV tape is related to the transmission efficiency and service life of the PV modules. The size, mechanical properties, surface structure, resistivity and other performance indicators of PV tapes are important factors affecting the efficiency of PV power generation, the breakage rate of PV cells, and the long-term reliability and durability of PV modules. High-quality, high-tech photovoltaic welding tape High-quality, high-tech photovoltaic welding tape can not only significantly improve the power generation efficiency, but also reduce the breakage rate of photovoltaic cells, to ensure the long-term stability of photovoltaic modules, is an important way for downstream photovoltaic power generation enterprises to achieve cost reduction and efficiency.
Photovoltaic tape manufacturing of photovoltaic modules in the middle of the industry chain. The PV industry chain mainly includes silicon, silicon wafers, cells, PV modules and PV application systems. The upstream of the industry chain is mainly silicon and silicon wafers; the midstream is mainly batteries and PV modules; and the downstream is PV application system. In the whole PV industry chain, PV module manufacturing with PV welding tape as raw material is in the middle of the industry chain. Upstream of the PV solder tape industry are mainly raw material suppliers such as copper, tin alloy and solder, and downstream customers are PV module manufacturers.
