Abstract
AbstractBoth 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.
