The invention relates to a high-efficiency seamless solar cell assembly serial welding method. The copper strip raw material is pressed into a long strip of special-shaped welding strip with multiple circulation units by a strip wire drawing coating device; it is divided into a single circulation unit by a strip cutting device The special-shaped ribbon section; the surface is uniformly coated with flux by the ribbon coating device; the special-shaped ribbon section is moved to the ribbon fixture tray, and arranged in the ribbon fixture tray according to the battery design pattern, and soldered Ribbon reel unit is formed after the tape jig tray is filled with special-shaped ribbon segments; the ribbon reel unit is moved to the cell stacking transmission line; the cell is moved to the cell stacking transmission line; the ribbon reel unit and the cell are stacked alternately to form a preform The battery string is transmitted to the heating and welding device through the stacking transmission line of the battery sheet, and the special-shaped ribbon segment in the preformed battery string is fully and evenly welded with the battery sheet through temperature heating to form a formed battery string. The special-shaped ribbon connection can reduce the connection distance of the battery sheet, and improve the power and light absorption effect of the battery module.
Description
technical field [0001] The invention relates to a high-efficiency seamless solar cell assembly serial welding method. Background technique [0002] At present, with the rapid development of global technology and economy, there is an increasing need for more and cleaner energy to meet demand. There is no carbon dioxide emission when solar energy generates power and the environmental burden is small, so many countries and regions are vigorously developing solar (such as photovoltaic) cells as energy. [0003] Monolithic solar cells are limited, and solar cell modules are a better choice. To achieve the function of generating electricity, solar cell modules need to connect single solar cells to make them a whole. At present, in the packaging process of solar cell modules, welding ribbons are used to connect single cells in series. [0004] With the continuous progress of research on high-efficiency solar cells in the industry, the rated operating current of most single-polyc...
