Silicon wafer, preparation method of silicon wafer, and passivation treatment solution

Abstract

A silicon wafer, a preparation method of the silicon wafer, and a passivation treatment solution is disclosed. The preparation method of the silicon wafer can include the following steps: providing a solar silicon ingot; cutting the solar silicon ingot with a first treatment solution to form a pretreated silicon wafer; degluing the pretreated silicon wafer with a second treatment solution to obtain a deglued silicon wafer; and cleaning the deglued silicon wafer with a third treatment solution to obtain the silicon wafer; wherein at least one of the first treatment solution, the second treatment solution and the third treatment solution comprises a non-metallic compound that is bonded with a silicon ion via a single bond.
