The present invention reduces the time required to manufacture a solar cell. After etching main surfaces (10B1, 10B2) of a crystalline silicon substrate (10B) using one etching solution, the main surfaces (10B1, 10B2) of the crystalline silicon substrate (10B) 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 (10B1, 10B2) of the crystalline silicon substrate (10B). |
