Embodiment Construction
[0026] As mentioned in the background art section, in the production of components in the prior art, it is necessary to use solder ribbons to connect the front side of a cell to the back side of an adjacent cell to form a series circuit. This design has the following characteristics: the components made of cells must be welded with ribbons, and the stress of welding will cause fragments of the cells; the temperature of welding will destroy the PN junction of the cells; The power loss caused by this is 3% to 4%. When the solar cell with this structure is formed into a module, a certain gap must be maintained between the cell and the cell directly for the bending of the solder ribbon. If the distance is too small, the fragmentation rate will increase.
[0027] Based on this, an embodiment of the present invention provides a solar cell structure, including a solar cell sheet, a front electrode is provided on the front side of the solar cell sheet, a back electrode and a back elect...
