    • 對於單晶矽太陽能電池，次波長結構在太陽能光電技術裡能有效降低光學上反射的損失。本研究利用時域有限差分法(FDTD)在波長範圍為0.3μm到1.2μm之間模擬太陽能電池上的次波長結構，利用模擬的技術在不同高寬比下評估不同對稱次波長結構的反射率變化。此外本論文也研究在不同厚度的抗反射層鍍膜對單晶矽太陽能電池上光學級幾何結構的反射率影響。根據FDTD分析不同高寬比的反射率顯示三角形結構在環氧樹脂中有效地降低反射損失。根據計算，高寬比為6.0的三角形結構反射率低於0.005(0.5%)。

    For single crystalline silicon solar cells, subwavelength structures (SWSs) applied to photovoltaic (PV) are essential to reduce the reflectance loss. This study investigated the SWSs applied to solar cell surfaces by using finite difference time domain (FDTD) method in the light spectrum from 0.3μm to 1.2μm. Using simulation techniques, the effects of different symmetrical profiles, such as triangular, quadratic, and parabolic, gratings with different aspect ratios were evaluated. Furthermore, this study explored the influence of reflectance reduction in the silicon crystalline solar cell with antireflection coating (ARC). Analyzing the reflectance of different aspect ratios by the FDTD method showed that triangular structures in optical grade epoxy reduced the reflection loss effectively. Based on the calculation, the reflectance was below 0.005 (0.5%) for triangular structures with the aspect ratio of 6.0.
