Provided is a method for manufacturing a solar cell in which a texture can be formed in a uniform manner on the surface of a silicon substrate. This invention is characterized in being provided with: a step for immersing the silicon substrate (2) in a first aqueous solution containing hydrofluoric acid, and removing the natural oxide film on the surface of the silicon substrate (2); a step for immersing the silicon substrate (2) from which the natural oxide film has been removed into a second solution containing metal ions, and causing the metal ions to adhere to the surface of the silicon substrate (2) by non-electrolytic plating; and a step for immersing the silicon substrate (2) to which the metal ions have been caused to adhere in a third solution containing hydrofluoric acid and hydrogen peroxide, and forming a porous layer (3) on the surface of the silicon substrate (2) by a catalytic reaction of the metal ions. |
