Manufacturing method for solar cell

In a processing of immersing substrates in a chemical solution, and agitating the chemical solution by as bubbles or liquid, the gas bubbles or liquid is supplied so as to bring about alternate occurrence of a first state and a second state. The first state is a state in which an amount of the gas bubbles or the liquid supplied to first side in one direction of each substrate is greater than an amount of the gas bubbles or the liquid supplied to a second side in the one direction of the substrate. The second state is a state in which the amount of the gas bubbles or the liquid supplied to the first side in the one direction of the substrate is smaller than the amount of the gas bubbles or the liquid supplied to the second side in the one direction of the substrate.

The present invention reduces the time required to manufacture a solar cell. After etching main surfaces (BB) of a crystalline silicon substrate (B) using one etching solution, the main surfaces (BB) of the crystalline silicon substrate (B) are etched at a lower etching rate than the etching performed using the one etching solution by using another etching solution that has a higher concentration of etching components than the one etching solution. In this way, a textured structure is formed in the main surfaces (BB) of the crystalline silicon substrate (B).
