<p>The present invention relates to a texturing method of a solar cell wafer. According to a texturing method of the present invention, a pyramid structure is formed on a surface by texturing an upper surface with a dry etching method using reactive ions on a quasi-single silicon crystal substrate. The pyramid structure improves the light absorption efficiency of a solar cell by reducing optical reflectivity. According to the present invention, the efficiency of the solar cell can be improved by effectively texturing the quasi-single silicon crystal substrate regardless of the orientation and kind of crystal.</p> |
