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.

A semiconductor wafer for a solar cell, comprising a plurality of grooves randomly formed on a surface of the semiconductor wafer of the solar cell, the grooves being formed by depositing a protector on the surface randomly, 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.
A method of making a semiconductor wafer for a solar cell, comprising:
- forming a plurality of grooves randomly on a surface of the semiconductor wafer, the grooves being formed by the method comprising of:
- depositing a protector on the surface randomly;
- 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.
