description The invention relates to the field of photovoltaic technology, in particular to a solar cell and a preparation method thereof, and a photovoltaic module, a plurality of rows of first welding spot groups and at least one row of second welding spot groups are distributed on the back surface of a cell piece of the solar cell along a first direction, and the second welding spot groups are distributed in an area, close to a cutting end or a chamfering end, of the cell piece. The first welding spot group is distributed in an area, far away from the cutting end or the chamfering end, of the battery piece; and along the first direction, the spacing distance between at least part of the welding spots of the second welding spot group and the welding spots in the adjacent first welding spot group is greater than the spacing distance between the welding spots of the adjacent first welding spot group. According to the solar cell provided by the invention, at least part of the welding spots of the second welding spot group
