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.
