The application belongs to the technical field of solar cells, and discloses a preparation method of a high-bifaciality back contact solar cell and a BC module containing the same. The preparation method comprises the following steps: firstly, ICP etching is performed on the front surface of a silicon wafer by dynamically adjusting the flow ratio of sulfur hexafluoride to oxygen in three stages to form a gradient composite textured surface; then, a mask layer is deposited on the back surface, and a complementary nano-pillar array microstructure is prepared through nano-imprinting and etching; finally, based on the spectral characteristics of the front and back surfaces, a matching gradient antireflection film and a light transmission film are respectively deposited. The application effectively reduces light reflection loss through the morphology coordination of the front gradient textured surface and the back microstructure, and the optical matching of the front and back film systems. The prepared cell has a front surface reflectivity of ≤3%, a back surface reflectivity of ≤4%, a bifaciality of ≥92%, and excellent stability. The BC module prepared by using the same is stable and reliable in long-term use.
