Abstract

The invention relates to an efficient seamless solar battery assembly series welding method. The method is characterized in that a copper strip raw material is pressed into a long-strip-shaped special-shaped solder strip with a plurality of circulating units through a solder strip wiredrawing and coating device; the solder strip is divided into special-shaped solder strip sections of a single circulating unit through a solder strip roll-off device; scaling powder is uniformly coated on a surface of the solder strip through a solder strip coating device; the special-shaped solder strip sectionsare moved to a solder strip jig disc and arranged in the solder strip jig disc according to a battery design pattern, and solder strip disc units are formed after the solder strip jig disc is filledwith the special-shaped solder strip sections; the solder strip disc units are moved to a battery piece stacking transmission line; battery pieces are moved to the battery piece stacking transmissionline; the solder strip disc units and the battery pieces are stacked in a staggered manner to form a preformed battery string; the battery pieces are transmitted to a heating welding device through the battery piece stacking transmission line, and the special-shaped solder strip sections are fully and uniformly welded in the preformed battery string with the battery pieces through temperature heating to form a formed battery string. The method is advantaged in that special-shaped solder strip connection can reduce a connection interval of the battery pieces and improve the power and the lightabsorption effect of a battery assembly.

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...
