Abstract
Provided is a method of manufacturing a solar cell, wherein a solar cell is manufactured by combining a damage removal etching process, a texturing process and an edge isolation process. The method is advantageous in that RIE and DRE are conducted, and then DRE/PSG and/or an edge isolation removal process are simultaneously conducted, so that the movement of a substrate (that is, a wafer) is minimized, thereby reducing the damage rate of the substrate.
