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.
Compared with the traditional photovoltaic ribbon assembly, the output power of the new photovoltaic ribbon assembly is increased by 0.5%, 1.18% and 2%, respectively, and the optical gain of the dense vertical stripe heterogeneous ribbon is the highest. The increasing demand for energy leads to energy crisis and global warming.
Soldering ribbons mainly play a role in connecting electricity in photovoltaic modules. Therefore, it is of great significance to study the influence of new photovoltaic ribbons on the power of solar cells and photovoltaic modules.
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.
PV ribbon is a hot-dip tinned copper conductor that collects current from photovoltaic cells and is the conductor that joins the individual solar cells and carries the current generated to the distribution system. There are two main types of PV ribbon: interconnect ribbon and bus bar ribbon.
According to IEC61215 standard, the light emitted by solar simulator is vertically incident on the surface of photovoltaic welding strip through glass and EVA. The change of surface structure of photovoltaic welding strip will change the reflection path of light on the surface of photovoltaic welding strip, affecting the size of α 1 in Fig. 1.
