Photovoltaic welding ribbonDuring the production process, we need to pay attention to the following main product parameters to deal with various problems in use:
1. Thickness
Problem: The thickness of the welding strip directly affects the strength and current carrying capacity of the welding. Too thin thickness may lead to weak welding, while too thick thickness may increase costs and affect flexibility.
2. Width
Problem to be solved: The width of the solder strip must be consistent with the width of the main grid line of the cell to ensure good contact and current conduction. Inappropriate width will lead to poor contact and energy loss.
3. Hardness
Problem to be solved: The hardness of the soldering ribbon determines the operability of the soldering ribbon during the soldering process. If it is too soft, it will be easily deformed, resulting in a weak soldering; if it is too hard, it may be difficult to tightly bond with the battery cell, affecting the soldering effect.
4. Resistance value
Problem to be solved: The resistance of the soldering tape affects the efficiency of current conduction. Too high resistance will cause heat generation, reduce the overall power generation efficiency, and may cause the component to overheat.
5. Material composition
Problem to be solved: The material of the welding strip (such as copper or aluminum) and its alloy composition affect its conductivity, corrosion resistance and weldability. High-quality materials can improve welding results and extend product life.
6. Surface treatment
Problem Solving: Surface treatment of the solder strip (such as tin plating or silver plating) can improve soldering performance and oxidation resistance. Good surface treatment can reduce oxidation during soldering and improve contact reliability.
7. Temperature stability
Problem: The performance stability of the soldering strip in high or low temperature environments is crucial. Stable temperature characteristics can ensure normal operation under extreme climatic conditions.
8. Strength
Problem to be solved: The tensile strength of the soldering ribbon directly affects its durability during use. Insufficient strength may cause the soldering ribbon to break when subjected to stress, affecting the reliability of the overall component.
in conclusion
Combining these parameters, manufacturers can prevent and optimize various problems that photovoltaic ribbons may face in actual applications, ensure the quality and performance of the final product, and improvePhotovoltaic modulesoverall efficiency and reliability.
