Abstract
Provided are a method for preparing a solar cell, a solar cell, and a photovoltaic module. The method for preparing a solar cell includes: performing double-sided texturing on a silicon substrate; performing boron diffusion on the silicon substrate to form a boron diffusion layer and a borosilicate glass layer on both a front side and a back side of the silicon substrate; the front side of the silicon substrate having a first region and a second region, and removing the borosilicate glass layer and the boron diffusion layer in the second region by using laser, wherein wet oxygen and dry oxygen are introduced during the boron diffusion on the silicon substrate with a ratio ω of the wet oxygen to the dry oxygen satisfying 0%<ω≤20%; a density ρof the borosilicate glass layer satisfies 1.32 g/cm≤2.65 g/cm.
