Abstract

The invention discloses a photovoltaic weldable conductive band, which is in a grid shape and comprises a conductive grid composed of conductive wires. The outer diameter of each conductive wire is 10-500 microns; and the grid aperture of the conductive grid is 5-500 microns. The conductive band is latticed and has a plurality of meshes, wherein the meshes cannot block light, so that compared withan existing lightproof conductive band, the provided conductive band can reduce the shading area and improve the generating capacity per unit area of a battery piece and an assembly. The invention also provides a battery piece series structure using the latticed conductive band. If the conductive band in the series structure is rectangular and spans each fine grid line, the positioning requirement for the conductive band can be greatly reduced in the series welding process, the cost of series welding equipment can be reduced, and meanwhile, the productivity of the series welding machine is improved.

Description

technical field

[0001] The invention relates to the field of photovoltaics, in particular to a weldable conductive strip for photovoltaics and its application. Background technique

[0002] Solar cell modules (also called solar panels, photovoltaic modules) are the core part of the solar power generation system. The solar battery module includes a battery string, and the battery string is composed of a plurality of solar battery slices laid in series in sequence. Two cells laid adjacent to each other are connected in series through a conductive tape (such as a photovoltaic ribbon), and the conductive tape is connected to the front of one of the cells and to the back of the other cell.

[0003] However, the existing conductive strips are not light-transmitting. After the conductive strip is connected to the front of the cell, the shading area of ​​the front of the cell will be increased, thereby reducing the power generation per unit area of ​​the cell and the module. Cont...
