The present application provides a method for preparing a TOPCON cell and a TOPCON cell. The preparation method includes steps of: double-sided texturing the silicon wafer multiple times. Polysilicon is deposited on the front side, and then phosphorus diffusion is performed to form a doped polysilicon layer and a phosphorosilicate glass; alternatively, the phosphorus diffusion is performed to form the phosphorus diffused layer and the phosphorosilicate glass. Laser grooving is performed to form localized emitters. After third double-sided texturing on the silicon wafer, the double-sided rounding is performed.
