研究目的
Investigating the impact of light trapping and multilayer antireflection coating on the electrical characteristics of heterojunction solar cells to improve efficiency and reliability against interfacial defects.
研究成果
The optimized SHJ solar cell with triangular texture and double ARC layer achieved a conversion efficiency of 20.06%, showing a 30% improvement over conventional planar cells and enhanced immunity to interfacial defects, with only a 3% efficiency degradation at high defect density compared to 30% for non-optimized devices. The GWO approach effectively optimized light trapping parameters, providing a foundation for developing high-performance and reliable solar cells.
研究不足
The study is based on an analytical model and simulations, lacking experimental validation. The optimization is specific to the assumed parameters and may not account for all real-world variations or fabrication challenges.
1：Experimental Design and Method Selection:
An analytical model was developed to study the impact of light trapping and double antireflection coating (ARC) on n(a-Si:H)/i(a-Si:H)/p(c-Si)/p+(C-Si) heterojunction solar cells with intrinsic thin layer (SHJ). The model incorporates a triangular texture morphology and uses the Grey Wolf Optimization (GWO) algorithm for optimization.
2：Sample Selection and Data Sources:
The study uses theoretical parameters and references experimental data from literature for comparison, with no physical samples described.
3：List of Experimental Equipment and Materials:
No specific equipment or materials are listed; the paper is analytical and computational, focusing on modeling and optimization.
4：Experimental Procedures and Operational Workflow:
The workflow involves developing the analytical model for reflection coefficient, photocurrent density, and current-voltage behavior, then applying the GWO algorithm to optimize parameters such as ARC thicknesses, refractive indices, texture angle, and height.
5：Data Analysis Methods:
Data analysis includes calculating photovoltaic parameters (JSC, VOC, FF, η) using the analytical model and comparing results with conventional planar solar cells.
