Abstract
The present disclosure relates to large cell sheets, solar cells, shingled solar modules, and manufacturing method thereof. A top surface of a boundary portion of units of the large cell sheet is divided into a cutting area, top surface bonding areas and top surface electrically-conductive contact areas. The cutting area is configured in a way that the large cell sheet can be cut along the cutting area; the top surface bonding areas and the top surface electrically-conductive contact areas are provided alternately, the cutting area and the top surface electrically-conductive contact areas are formed as an overlapping edge of the solar cell, and after the splitting of the large cell sheet, the top surface electrically-conductive contact areas can directly contact the bottom surface of another solar cell to achieve electrically-conductive connection. The large cell sheet according to the present disclosure can be split conveniently, and the individual solar cells are provided with dedicated bonding areas and electrically-conductive contact areas. Such an arrangement can optimize the production process and use performance of the solar cells.
