The invention relates to a back passivation structure capable of reducing phosphorus internal expansion. The back passivation structure comprises an N-type crystal silicon wafer, and a tunneling oxide layer, an intrinsic amorphous silicon layer, a silicon oxynitride layer and a phosphorus-doped polycrystalline silicon layer which are sequentially arranged on the back surface of the N-type crystal silicon wafer. According to the back passivation structure capable of reducing phosphorus internal expansion, in the preparation process, P atoms can be diffused towards the silicon substrate after high-temperature crystallization, the silicon oxynitride layer serves as a first barrier layer, silicon oxynitride has higher barrier efficiency on the P atoms compared with silicon oxide, most of the P atoms can be effectively blocked, and the performance of the silicon oxynitride layer is improved. The intrinsic amorphous silicon layer serves as a second barrier layer, P atoms which are not blocked by the silicon oxynitride layer can be subjected to P doping with intrinsic amorphous silicon and are converted into doped polycrystalline silicon with low P concentration, and the tunneling oxide layer serves as the last barrier layer to further block the P atoms, so that the P atoms can be effectively prevented from being internally expanded to a crystalline silicon substrate, surface recombination is reduced, and the performance of the crystalline silicon is improved. Therefore, the cell conversion efficiency is improved.
