<p>Provided is a method for manufacturing a solar cell, which is capable of providing the surface of a silicon substrate with more uniform texture. A method for producing a solar cell (1), wherein a porous layer (3) is formed on the surface of a silicon substrate (2) by etching using metal ions (5), is characterized by comprising: a step wherein the silicon substrate (2) is immersed in a first aqueous solution containing a strong acid and the metal ions (5), and the metal ions (5) are caused to adhere to the surface of the silicon substrate (2) by electroless plating; and a step wherein the silicon substrate (2), to the surface of which the metal ions (5) have been caused to adhere, is immersed in a second aqueous solution containing hydrofluoric acid and hydrogen peroxide solution, and the porous layer (3) is formed on the surface of the silicon substrate (2) by a catalytic reaction of the metal ions (5).</p> |
