The invention discloses a back-passivated crystalline silicon solar cell and a preparation method thereof. Molybdenum oxide is used as a p-type crystalline silicon passivation layer and a hole transport layer, and the solar cell has the following structure: Ag/SiNx/n-C-Si/p-C-Si/SiO2/MoO3/Al/Ag, where x=0. 9-1.2, and n-C-Si is phosphorus doped n-type crystalline silicon. The invention uses molybdenum oxide instead of alumina as the back passivation material of the p-type crystalline silicon cell, and thus the recombination of the back side of the cell can be greatly reduced and the molybdenumoxide can also be used as the hole transport layer of the p-type crystalline silicon cell. Therefore, in the actual production process of the cell, the laser drilling is not required to ensure the transmission of carriers like PERC cells, which can not only reduce the backside recombination of crystalline silicon, but also avoid the negative impact of laser drilling.
