| dc.description.abstract | 本論文研究重點為了拓展矽薄膜太陽能電池對太陽光頻譜的吸收，因此在單一p-i-n的結構下，於本質層中堆疊非晶矽與不同結晶率的微晶矽，利用模擬軟體AMPS-1D有系統地探討不同的堆疊對太陽光吸收的響應。
研究結果顯示：一、在只有單一本質層的矽薄膜太陽能電池中，本質層的材料會影響最佳效率的是厚度；當使用結晶率越高的微晶矽薄膜，其需要更大的厚度才可以達到最佳的效率；二、本質層以雙層堆疊時，若要有效的增加太陽的光萃取，非晶矽與微晶矽其材料厚度與排列方式對於頻譜響應有很大的影響；三、在固定厚度下，雙層結構中以”微晶矽–非晶矽”的堆疊結構對於光吸收有較好的表現，而這樣的結構中也擁有較高的短路電流 (Jsc) 與填充因子 (FF)。當結構為微晶矽–非晶矽的排列，厚度各為單位厚度的4倍，則效率最高可以達到11.1%。

| dc.description.abstract | The thesis aims on the improvement of the efficiency of the silicon thin-film solar cell by better extraction of solar spectrum. We have analyzed the influence of the spectral response using AMPS-1D simulator by stacking amorphous silicon and microcrystalline silicon with different crystalline volume fraction of the intrinsic layer in p-i-n structure.
The thesis reveals the following results: first, the optimized thickness of the intrinsic layer is related to the crystalline volume fraction of the microcrystalline silicon. The thickness of an i-layer with a higher crystalline volume fraction must be thicker to obtain higher efficiency. Second, when the intrinsic layer was constructed by two layers, an amorphous layer and a microcrystalline layer, the spectral response of the device is influenced by both layer thickness and arrangement. Third, for a fixed thickness, the layer structure of the ＂microcrystalline silicon – amorphous silicon＂ is better for extraction of solar spectrum. The structure also features the highest Jsc and FF with 90% crystalline volume fraction of the microcrystalline silicon and amorphous silicon stack. The conversion efficiency can reach 11.1% .
