Multilayer antireflection coatings design for SiO₂‐passivated silicon solar cells

Abstract

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.

Recent Applications of Antireflection Coatings in Solar Cells

“…Because the DLARC could only effectively reduce the reflectance in a tral range, more and more studies have adopted three or more antireflectio tain lower reflectivity and wider spectral width. X.J.Xiao et al [46] selected als, SiC, HfO2, SiO2, and MgF2, and Md. Shaon Sarker et al [47] selected th ZnS, Si3N4, and MgF2, who both designed and simulated three types of AR lation results showed that the TLARC was better than the DLARC in redu tion and improving cell efficiency.…”

Numerical Exploration and Statistical Analysis of Mathematical Parameters of Anti Reflecting Coating on Operational Parameters Improvement of Solar Cell

“…These coatings are typically very thin, with an optical thickness of about one-quarter to one-half the incident wavelength. The antireflector single-layer coating is only effective against reflection for a single wavelength, resulting in high-quality solar cells [38][39][40][41][42][43][44][45][46][47][48][49][50]. Precise PV modules optical assessment is not easy.…”
