Abstract:
1. A method of manufacturing a solar cell, comprising: sawing a substrate and then removing a damage from a surface of the substrate using an SDR (saw damage removal) process; texturing the surface of the substrate using an RIE (reactive ion etching) process; doping the surface of the substrate with a doping material different from a material constituting the substrate; simultaneously removing a damage and an oxide film (phosphoric silicate glass (PSG)) from the surface of the substrate; forming an anti-reflective coating on the surface of the substrate; irradiating an edge of the substrate with laser using laser etching to isolate the edge from the antireflective film; and metallizing the substrate to form a front electrode and a rear electrode on front and rear sides thereof.
