Abstract: A back contact solar cell string includes at least two cell pieces, each cell piece including P-type doped regions and N-type doped regions that are alternately arranged, the P-type doped regions including positive electrode thin grid lines, and the N-type doped regions including negative electrode thin grid lines; and a plurality of conductive wires connected to the positive electrode thin grid lines and the negative electrode thin grid lines. The conductive regions configured for electrical connection between each conductive wire and the positive electrode thin grid lines or the negative electrode thin grid lines and insulation regions configured for insulating connection between each conductive wire and the negative electrode thin grid lines or the positive electrode thin grid lines are alternately disposed at joints between each conductive wire and the positive electrode thin grid lines, and at joints between each conductive wire and the negative electrode thin grid lines.
