Problems solved by technology

[0011] Disadvantage of prior art 1: the disadvantage of this technical solution is that the amount of silver paste used on the front and back electrodes is relatively large, so the cost of laminated cells is relatively high
Therefore, there are disadvantages of large consumption of silver paste and high cost.

Abstract

The present invention belongs to the technical field of solar cells, and particularly relates to an interconnection structure between solar laminated cells and a solar laminated cell. The interconnection structure is used for sequentially bonding at least two cells and forming a good electrical connection. A front electrode and / or a back electrode of the cell are / is of a hollow structure. The back electrode of the previous cell is connected with the front electrode of the next adjacent cell by using conductive glue, so that a lot of front and back electrode paste is saved, and the cost of the laminated cell is lowered. For a back fragmented hollow design, the interconnection structure also can help reduce the amount of the used conductive glue and the cost of the laminated cell.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of solar cells, and in particular relates to an interconnection structure between sheets of solar laminated cells and a solar laminated cell. [0003] 【Background technique】 [0004] A solar cell is a device that uses the photovoltaic effect to directly convert light energy into direct current. According to different photoelectric conversion materials, solar cells include monocrystalline silicon, polycrystalline silicon, amorphous silicon thin films, cadmium telluride thin films, copper indium gallium tin thin films, gallium arsenide, fuel sensitization, perovskite, stacked layers, etc. . The most common of these are crystalline silicon solar cells, including monocrystalline silicon solar cells and polycrystalline silicon solar cells. [0005] A photovoltaic device that can be used for a long time is obtained by electrically interconnecting multiple solar cells and encapsulating them in glass or or...
