<p>PROBLEM TO BE SOLVED: To provide a method of performing surface treatment of a substrate for solar cell, especially of a pseudo single crystal substrate, effectively regardless of the type and directivity of crystal.SOLUTION: In a method of performing surface treatment of a substrate for solar cell, a pyramid structure is formed on the surface of a substrate by performing a first wet etching step, a reactive ion etching step, and a second wet etching step. Such a pyramid structure contributes to enhancement of light absorption efficiency of a solar cell, by lowering the optical reflectance. Efficiency of a solar cell can be enhanced by performing surface treatment of a pseudo single crystal substrate effectively, regardless of the type and directivity of crystal.</p> |
