METHOD FOR MANUFACTURING A SOLAR CELL

摘要

The present invention relates to a method for manufacturing a solar cell, which is capable of significantly reducing the amount of wastewater generated during a wet-etching process and improving the efficiency of the solar cell. The method according to the present invention comprises: texturing in order to form an uneven structure on one semiconductor substrate surface by etching the semiconductor substrate surface with a texturing device; forming a temporary layer at an upper portion of the semiconductor substrate surface so as to surround a first byproduct layer which is formed at a predetermined region of the semiconductor substrate surface during the texturing; and doping the semiconductor substrate surface with a predetermined dopant using a doping device so as to form a first semiconductor layer and a second semiconductor layer disposed above the first semiconductor layer and having a different polarity than the first semiconductor layer. The first byproduct layer and the temporary layer are simultaneously removed.
