Title:
SOLAR CELL MODULE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/262163
Kind Code:
A1
Abstract:
Disclosed are a solar cell module and a preparation method therefor. The module comprises: a plurality of cell strings, each cell string comprising a plurality of cells connected in series, a conductive structure arranged between each two adjacent cells, and a supporting heat transfer block; in each two adjacent cells of the cell string, there is an overlapping area between the back surface of a first cell and the front surface of a second cell; part or all of the conductive structure is positioned in a partial area of the overlapping area, and is used for connecting the two adjacent cells in series; and part or all of the supporting heat transfer block is positioned in an area of the overlapping area in which the conductive structure is not positioned in order to dissipate the heat of the cells. The present module effectively ensures the stability of the solar cell module, preventing hidden cracks and damage; the heat transfer efficiency of the module is increased, reducing the high temperature caused by the hot spot effect, and preventing cell panels from being overheated and burned out or having hidden cracks and damage and thereby excessively consuming the energy of the module, thus increasing the power generation efficiency of the module.
