Abstract

The invention provides a double-sided battery assembly structure. The double-sided battery assembly structure comprises at least one group of battery strings formed by connecting a plurality of battery pieces, the double-sided battery assembly structure further comprises grid lines arranged on the surfaces of the battery pieces, in the same battery string, the surfaces, provided with the grid lines, of the adjacent battery pieces are located on the same plane, and in the extending direction of the battery string, the grid line on the previous battery piece is connected with the grid line on the next battery piece. According to the arrangement mode, the grid lines for connecting the adjacent battery pieces are positioned on the same plane, so that components such as a welding strip can be connected with the adjacent battery pieces without passing through areas between the adjacent battery pieces, and the area of the module can be fully utilized by shortening the distance between the twobattery pieces or directly adjoining the battery pieces.

Description

technical field [0001] The present invention relates to the field of photovoltaic technology, in particular to a double-sided battery assembly structure. Background technique [0002] With the increasingly severe energy and environmental problems, the utilization of clean and renewable energy is urgent. Among them, photovoltaic power generation technology has developed rapidly and become increasingly mature, and the application of photovoltaic cells is gradually becoming popular. In order to further improve the conversion efficiency of photovoltaic cells, reduce preparation costs, and achieve grid parity, new cell and module technologies are constantly being developed. In conventional photovoltaic modules, the cells are interconnected by ribbons. This interconnection method will result in a blank area between the cells. One end of the ribbon is connected to the front electrode of a cell. , the other end can be connected to the back electrode of another cell through this bla...
