Photovoltaic welding ribbon, also known asTinned copper striporTinned copper strip,yesPhotovoltaic modulesIt is an important component of photovoltaic cells and is used to connect photovoltaic cells when packaging photovoltaic cells. It guides the electrical energy converted from light on the silicon wafer to electrical equipment and plays an important role in conducting and gathering electrical energy to increase the output voltage and power of photovoltaic modules. Photovoltaic cells and photovoltaic modules connected by photovoltaic ribbons are directly used in the construction of photovoltaic power generation systems.

The quality of photovoltaic ribbons is related to the transmission efficiency and service life of photovoltaic modules. The performance indicators of photovoltaic ribbons such as size, mechanical properties, surface structure, resistivity, etc. are important factors affecting photovoltaic power generation efficiency, breakage rate of photovoltaic cells, and long-term reliability and durability of photovoltaic modules. High-quality, high-tech photovoltaic ribbons High-quality, high-tech photovoltaic ribbons can not only significantly improve power generation efficiency, but also reduce the breakage rate of photovoltaic cells and ensure the long-term stability of photovoltaic modules. They are an important way for downstream photovoltaic power generation companies to reduce costs and increase efficiency.

Photovoltaic modules manufactured with photovoltaic ribbons are in the middle of the industry chain. The photovoltaic industry chain mainly includes silicon materials, silicon wafers, batteries, photovoltaic modules and photovoltaic application systems. The upstream of the industry chain is mainly silicon and silicon wafers; the midstream is mainly batteries and photovoltaic modules; the downstream is photovoltaic application systems. In the entire photovoltaic industry chain, the manufacture of photovoltaic modules using photovoltaic welding ribbons as raw materials is in the middle of the industry chain. The upstream of the photovoltaic welding ribbon industry is mainly raw material suppliers such as copper, tin alloys and solders, and the downstream customers are photovoltaic module manufacturers.
