The present disclosure relates to the technical field of solar cells. Disclosed are a solar cell, a preparation method therefor and a use thereof. A P-type doped region and an N-type doped region are alternately arranged on the back surface of a crystalline silicon substrate; a boron diffusion doped layer, a first passivation layer and a first anti-reflection layer are sequentially formed in the P-type doped region; and a phosphorus-doped silicon oxide layer, a phosphorus-doped polycrystalline silicon layer, a second passivation layer and a second anti-reflection layer are sequentially formed on the surface of the crystalline silicon substrate in the N-type doped region.
