The present inventive concept relates to a solar cell manufacturing method, a solar cell manufactured thereby, and a substrate for a solar cell. The solar cell manufacturing method involves forming a separating portion for separating a substrate, which is for manufacturing the solar cell, into a plurality of pieces. The solar cell manufacturing method comprises: a step for preparing the substrate; a first substrate etching step for forming a first groove in one surface of the substrate; a second substrate etching step for forming a second groove inside the first groove; and a third substrate etching step for etching the substrate including the second groove, wherein the separating portion includes the first groove and the second groove.

Substrate for solar cell, solar cell, and solar cell manufacturing method

The present invention relates to a method for manufacturing a solar cell, comprising: a seating process of seating, in a processing space for manufacturing a solar cell, a cell in which a plurality of thin film layers are formed; a coating process of spraying a conductive material onto the cell; and a scribing process of irradiating a laser toward the cell to form a cell separation unit for separating the cell into a plurality of unit cells.

Method for manufacturing solar cell

The present inventive concept relates to a solar cell, a unit cell included in the solar cell, and a method for manufacturing the solar cell, the solar cell comprising: a first unit cell manufactured using any one piece from among a plurality of pieces formed by separating a mother substrate; and a second unit cell coupled to the first unit cell, wherein the first unit cell comprises a first cell electrode provided on a first unit substrate and having conductivity, the second unit cell comprises a second cell electrode provided on a second unit substrate and having conductivity, and the second cell electrode and the first cell electrode are bonded to each other without a bonding material to couple the second unit cell to the first unit cell.
