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 is photovoltaic welding strip?

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.

How welding strip affect the power 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 so-called photovoltaic welding strip is to coat binary or ternary low-melting alloy on the surface of copper strip with given specification.

What is the packaging process of photovoltaic modules?

The packaging process of photovoltaic modules is described as follows: The core of cell is the internal PN junction. According to the current diffusion technology, the voltage at both ends of the battery is about 0.50 V, and the working current is about 8 A.

Does surface structure of heterogeneous welding strip affect power enhancement of photovoltaic module?

In order to study the influence of the surface structure of heterogeneous welding strip on the power enhancement of photovoltaic module, three kinds of heterogeneous welding strips are selected for theoretical simulation. Meanwhile, a conventional welding strip is selected as the comparison sample.

How does a photovoltaic module work?

The cells are joined to each other by a flat ribbon to form the typical strings that then go to form the photovoltaic module. Mechanical and thermal stress is reduced to a minimum, with a cell breakage percentage of less than 0.3%.
