Abstract
The invention provides a photovoltaic solder strip and a preparation method thereof, and relates to the technical field of photovoltaic power generation, the photovoltaic solder strip comprises a conductive substrate and a solder coating the outer side of the conductive substrate; the photovoltaic solder strip is of a waveform structure. According to the photovoltaic welding strip, the conductivebase material is arranged to be of a waveform structure and the solder coats the conductive substrate to form the photovoltaic solder strip. The solder is sucked into the pores formed by the waveformstructure of the photovoltaic solder strip through the capillarity of the solder in the welding process, the contact area of the battery piece and the solder is increased, pseudo soldering and missingsoldering are avoided, the welding strength is improved, and meanwhile the process difficulty of welding through the photovoltaic solder strip is reduced.
Description
technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic welding ribbon and a preparation method thereof. Background technique [0002] Photovoltaic ribbon is an important raw material in the welding process of photovoltaic modules. The quality of photovoltaic ribbon will directly affect the current collection efficiency of photovoltaic modules and greatly affect the power of photovoltaic modules. [0003] The current photovoltaic ribbons are all straight-line structures. When welding the photovoltaic ribbons with this structure, it is easy to cause virtual soldering and empty soldering due to uneven solder distribution, which affects the power of the photovoltaic module. Contents of the invention [0004] The problem to be solved by the invention is that the phenomenon of virtual welding and empty welding tends to occur when the photovoltaic ribbon is welded. [0005] In order to solve the above...
