Both the passivation and good antireflection effect can improve the power conversion efficiency of the crystalline silicon solar cells. In this study, we simulated and optimized HfO2 single‐layer, SiO2/SiC double‐layer, and MgF2/HfO2/SiC triple‐layer antireflection coatings and obtained the optimal optical parameters based on the optical transfer matrix. In addition, we analyzed the influence of HfO2, SiO2/SiC, and MgF2/HfO2/SiC antireflection coatings on the performance of the crystalline silicon solar cell. The results indicated that the HfO2, SiO2/SiC, and MgF2/HfO2/SiC antireflection coatings increased the power conversion efficiency of the crystalline silicon solar cell from 12.17?% to 17.13?%, 18.57?%, and 18.85?%, respectively. For cost‐saving, the SiO2/SiC double‐layer antireflection coating is a good choice for the crystalline silicon solar cell.(#br)The HfO2 single‐layer, SiO2/SiC double‐layer, and MgF2/HfO2/SiC triple‐layer antireflection coatings were simulated and analyzed for SiO2‐passivated crystalline silicon solar cell. The results indicated that the different antireflection coatings can increase photons entering the cell, further improve the power conversion efficiency of the cell.
