Abstract

The invention relates to the technical field of solar cells, in particular to a manufacturing method of a solar cell piece, which comprises the following steps of: forming an original solar cell piece which comprises a transparent conductive layer; segmenting the original solar cell piece to form at least two sliced solar cell pieces; at least cleaning the segmentation surfaces of the sliced solar cell pieces by adopting a dry cleaning process; and after the dry cleaning process is carried out, forming grid line electrodes on the surfaces of the sliced solar cell pieces. According to the manufacturing method of the solar cell piece, the problem that the photoelectric conversion efficiency of the solar cell is reduced due to segmentation can be solved by adjusting the forming sequence of the grid line electrodes and removing the residual fragments of the transparent conducting layer due to segmentation by adopting a dry cleaning process.
