Photovoltaic welding ribbon<\/a>Also known asTinned copper strip<\/a>or tinned copper wire, available in countersunk solder strips and connecting strips, used to connect thousands ofPhotovoltaic modules<\/a>Battery. Welding tape is an important raw material in the photovoltaic module welding process. The general selection criteria are to determine the thickness of the tape according to the thickness of the battery cell and the size of the short-circuit current. The width of the tape should be equal to the width of the battery main wire, and the softness of the tape generally depends on the thickness of the battery cell and the welding tool.<\/p>\n

The structure of the photovoltaic strip<\/p>\n

\u2460Through copper-based materials: solidified copper (99.9%), oxygen-free copper (99.95%) and red copper.<\/p>\n

\u2461Through the tin coating layer:<\/p>\n

60%Sn 40%Pb<\/p>\n

62%Sn 36%Pb 2%Ag<\/p>\n

96.5Sn 3.5%Ag, etc.<\/p>\n

\u2462 According to hardness:<\/p>\n

1. Soft 2. Extra soft 3. Super soft 4. Super soft plus<\/p>\n

Method for processing tinned strips<\/p>\n

1. Copper strip cutting-annealing-tinning.<\/p>\n

2. Copper wire flattening - annealing - tinning<\/p>\n

Advantages:<\/p>\n

1. The welding surface is smooth after shearing.<\/p>\n

2. The integrity of the crystal structure.<\/p>\n

shortcoming:<\/p>\n

Burrs on all sides<\/p>\n

*Note: The elongation at break of photovoltaic ribbon is related to the hardness of the ribbon. Generally speaking, the softer the ribbon, the greater the elongation at break.<\/p>","protected":false},"excerpt":{"rendered":"
