摘要： The present invention 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.
