Problems solved by technology

During the transfer process of the battery string, the cells are easily affected by external forces, which increases the probability of cracks, and the cracks of the cells will affect the performance of solar cell modules
Moreover, during the battery string transfer process, the conductive connectors will bear a certain amount of tension, and the serial connection (the connection between the conductive connector and the battery sheet) will also withstand a certain amount of tension. If the tensile strength of the conductive connectors is not enough, the conductive The connector may be torn or broken during the transfer of the battery string. If the tensile streng...

Abstract

The invention provides an L-shaped connecting member for a solar cell sheet. The L-shaped connecting member comprises an L-shaped conductive substrate. The L-shaped conductive substrate comprises a first side and a second side which extend in the same direction, wherein the first side is attached to the side surface of the solar cell sheet, and the second side is attached to the front surface or the back surface of the solar cell sheet. The first side and the second side are integrally connected with each other to form an L shape. The inner side surface of the first side is covered with insulating glue. The inner side surface of the second side is covered with solder tin or a conductive adhesive. The invention also provides the use of the L-shaped connecting member. The L-shaped connectingmember of the present invention has a specially designed three-dimensional structure such that the front electrode and the back electrode of the solar cell sheet can extend to the side surface of thesolar cell sheet, which facilitates the serial connection of the solar cell sheets and the close arrangement of the solar cell sheets.

Description

technical field [0001] The invention relates to an L-shaped connector for a solar cell and an application thereof. Background technique [0002] Solar cell modules (also called solar panels, photovoltaic modules) are the core part of the solar power generation system. A solar cell module refers to the smallest indivisible solar cell combination device with external packaging and internal connections that can provide direct current output alone. It is mainly composed of solar cells, tempered glass, EVA, backplane and frame. [0003] The manufacturing method of the solar battery module mainly includes the following steps: connecting battery slices in series, stacking modules, laminating modules, and framing. [0004] Among them, the series connection of battery slices is mainly: a plurality of battery slices are tiled and serially connected in series along a certain arrangement direction, and the multiple battery slices are connected in series to form a battery string; The f...
