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.
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.
The so-called photovoltaic welding strip is to coat binary or ternary low-melting alloy on the surface of copper strip with given specification. The methods of continuously and evenly coating low-melting metals and alloys on the metal strip include electroplating, vacuum deposition, spraying and hot-dip coating.
In the photovoltaic module, the photovoltaic welding strip is packaged in EVA, and the reflected light from the surface of the photovoltaic welding strip passes through EVA and glass and enters the air. The transmission path of light is shown in Fig. 1.
