Abstract
A textured semiconductor wafer for a solar cell includes a plurality of grooves being formed on a surface of the semiconductor wafer. The grooves are formed in the step of depositing a protector in the form of islands on the surface by spray process or screen-printing process, dipping the wafer into an isotropic etching solution to etch a portion of the surface where the protector is not deposited, and removing the protector.
