摘要

單晶矽太陽電池表面上的三角結構及結構上的抗反射膜層，皆有助於增加太陽電池的轉換效率。藉助有限差分時域 (finite difference time domain, FDTD) 法，可計算多層結構的反射與透射。利用電池受光面的量測數據，可修正單晶矽太陽電池反射率的量測值。與模擬反射率的數據相比，其與量測反射率間的誤差為0.33%。接著，採用導納軌跡法，來分析具有抗反射雙層膜的電池模組的性能。另外，利用FDTD所計算的抗反射雙層膜電池模組的反射率，經轉換成短路電流，可用以分析模組的性能。按照抗反射的模擬結果，經以模擬數值實際鍍製雙層抗反射膜結構，發現電池模組的短路電流可提升1.66%。

Both of triangular texture and antireflection (AR) coating on the surface of monocrystalline silicon solar cells are useful for increasing conversion efficiency of solar cells. Using the method of finite difference time domain (FDTD), the reflectance and transmittance of the multi-layer structure can be calculated. By means of the measuring data of illuminated area on the cell surface, the measured reflectance of monocrystalline silicon solar cell can be corrected. Comparison with the simulation data of reflectance, the error between it and the measured reflectance is 0.33%. The performance of AR double-layer on solar module is then analyzed with the method of admittance locus. In addition, the reflectance computed by FDTD of AR double-layer on solar module can be transformed into short-circuit (SC) current to analysis the performance of the module. The SC current of solar module coated AR double-layer based on simulation data is increased by a factor of 1.66%.
