Abstract

A method for manufacturing a solar cell capable of significantly reducing the amount of wastewater generated during a wet-etching process and improving the efficiency of the solar cell. A method comprising: texturing 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 to surround a first byproduct layer 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 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.
