Problems solved by technology

However, the usual soldering strips are disc-shaped, and the width used to connect the upper and lower cells after cutting is the same. If you want to use narrow interconnecting strips for the main grid line, use wide interconnecting strips for the back electrode. In the current conventional soldering belt is not possible
It can also be welded in sections, but the operation is inconvenient

Abstract

The invention relates to the technical field of photovoltaic modules, in particular to a novel interconnection strip for a photovoltaic solar module and battery plates for matched use. The interconnection strip is provided with a strip body, one end of the body is a thin part, the other end of the body is a wide part, the thin part is welded with main grid lines on the fronts of the battery plates, and the wide part is welded on a back electrode at the backs of the battery plates so as to increase the area of the interconnection strip, decrease the series resistance between the battery plates, lessen the line loss of the current on a welding strip of the interconnection strip and increase the output power of the module.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a new type of interconnection bar for photovoltaic solar modules and battery sheets for supporting use. Background technique [0002] In photovoltaic modules, generally speaking, the front busbars and the back electrodes of the cell are symmetrical. Generally, the width of the front busbars is 1.5mm to 2.1mm, and the width of the back electrodes is 3mm to 4mm. The gate line width is mainly designed considering the offset of welding. In order to increase the power of cells and components, the main grid line can be narrowed to increase the light-receiving area, or the back electrode and the back interconnection strip can be widened without changing the main grid line, and the series resistance can be reduced by increasing the area of ​​the back interconnection strip , thereby increasing the output power of the module. However, the usual soldering strips are disc-shap...
