1. A manufacturing apparatus of a solar cell string, which is configured to arrange a buffer pad for the solar cell string, wherein the solar cell string comprises at least two solar cells comprising a first solar cell and a second solar cell adjacent to each other, a front surface and a back surface of each of the at least two solar cells are respectively provided with a grid line, the grid line on the front surface of the first solar cell is connected with the grid line on the back surface of the second solar cell by a solder strip, and the first solar cell and the second solar cell have an overlapping region,
wherein the manufacturing apparatus comprises:
a solar cell separating mechanism, configured to make a relative movement between the first solar cell and the second solar cell adjacent to each other of the solar cell string, so as to separate the first solar cell and the second solar cell in the overlapping region in a direction perpendicular to a main surface of the first solar cell, so as to lay a pad into the overlapping region.
