Abstract: A method of manufacturing a solar cell includes forming jagged portions non-uniformly on a surface of a substrate, forming a first type semiconductor and a second type semiconductor in the substrate, forming a first electrode to contact the first type semiconductor, and forming a second electrode to contact the second type semiconductor. An etchant used in a wet etching process in manufacturing the solar cell includes about 0.5 wt % to 10 wt % of HF, about 30 wt % to 60 wt % of HNO3, and up to about 30 wt % of acetic acid based on total weight of the etchant.

Abstract: A solar cell and a method of manufacturing the same are provided. The solar cell includes a semiconductor unit, an electrode, and a passivation layer between the semiconductor unit and the electrode. The passivation layer includes a first layer containing silicon oxide (SiOx), a second layer containing silicon nitride (SiNx), and a third layer containing silicon oxide (SiOx) or silicon oxynitride (SiOxNy).
