Abstract: A method for manufacturing a solar cell may include forming a textured structure including multiple convex parts by etching a crystalline silicon substrate with etching liquid and forming an amorphous silicon layer on the crystalline silicon substrate with the textured structure formed thereon, by chemical vapor deposition or sputtering. An alkaline solution including at least one of a solution of sodium hydroxide and a solution of potassium hydroxide, additive including at least one of 4-propylbenzoic acid, 4-t-butylbenzoic acid, 4-n-butylbenzoic acid, 4-pentylbenzoic acid, 4-butoxybenzonic acid, 4-n-octylbenzenesulfonic acid, caprylic acid, and lauric acid may be added to the etching liquid. The textured structure may a chamfered section between main sloped surfaces of the convex parts, and a sharp trough part which is sandwiched by adjacent multiple convex parts.
