SOLAR CELL MANUFACTURING METHOD |
摘要 |
A solar cell manufacturing method includes: forming a first amorphous semiconductor layer of one conductivity type on a main surface of a semiconductor substrate; forming an insulation layer on the first amorphous semiconductor layer; etching to remove the insulation layer and the first amorphous semiconductor layer in a predetermined first region; forming a second amorphous semiconductor layer of an other conductivity type on the insulation layer after the etching, the other conductivity type being different from the one conductivity type; and etching to remove the second amorphous semiconductor layer in a predetermined second region, wherein the etching to remove the insulation layer and the first amorphous semiconductor layer in a predetermined first region includes: applying an etching paste to the insulation layer in the predetermined first region; and etching to remove the insulation layer and the first amorphous semiconductor layer in the predetermined first region using the etching paste. |
