Problems solved by technology

However, in the shingled modules currently on the market, there is no welding ribbon between the cells, and the two sides of the cells are interconnected by conductive glue, so there is a greater risk of cracks in the battery string. The entire battery string fails, which affects the power output of the module

Abstract

The present invention provides a grid soldering strip, a method for manufacturing the same, an apparatus for manufacturing the same, and an imbricate component. The back surface of an imbricate component cell sheet is dot-shaped back silver distributed in a grid shape. Grid soldering strips are soldered to the entire back surface of each cell sheet. The junction node of the grid soldering strips and the dot-shaped back silver of the cell sheet are matched and soldered so as to make the stress distribution of the cell sheet more uniform after soldering, improve a battery string's anti-crackingability. Even if the battery is cracked, the current can still be transmitted through the soldering strip, thereby reducing a risk caused by the crack.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a grid welding strip, its manufacturing method, its manufacturing device and a shingled assembly. Background technique [0002] With the development of photovoltaic technology, stacking technology has become an important technical means to increase the power of modules. Recently, shingled photovoltaic modules can increase the power of modules by reducing the gap between cells and increasing the area of ​​cells for power generation of the same size module. 20-30W. However, in the shingled modules currently on the market, there is no welding ribbon between the cells, and the two sides of the cells are interconnected by conductive glue, so there is a greater risk of cracks in the battery string. The entire battery string fails, which affects the power output of the module. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned...
