Electric solar container spot welding

How does a spot weld work?

During the weld process, two electrodes press sheets of metal together and convert the welding current into heat at the metals contact surface, as a result of which a permanent fixed joint, or spot weld, is created between the two metal sheets.

How to reduce the shading area of a photovoltaic welding strip?

The shading area of the photovoltaic welding strip is reduced by reducing the width of the main grid line and the PV welding strip, and the total amount of light received by the solar cell is increased. However, the contact resistance of the whole PV assembly is too large, which increases the electrical loss of the photovoltaic module.

What are the physical properties of solar cell welding materials?

The thickness of silicon wafer is 160 μm, the thickness of PV copper strip is 0.1 mm, the thickness of Sn alloy coating is 15 μm and 25 μm respectively. The physical properties of materials used in solar cell welding are shown in Table 6.

How welding strip affect the power of photovoltaic module?

The welding strip is an important raw material in the welding process of photovoltaic module. The quality of welding strip will directly affect the current collection efficiency of photovoltaic module, so it has a great impact on the power of photovoltaic module.

What is Kuka spot welding?
