| dc.description.abstract | 近年來，為了要增加太陽光的萃取，抗反射結構被廣泛的使用在各種太陽光伏元件上。在本論文中主要想利用抗反射結構去提升太陽電池的轉換效率。首先，為了要比較有無結構的差異性，使用無結構的異質接面太陽電池作為基準去探討。此外，藉由加入本質的非晶矽氫緩衝層，不僅可以抑制漏電流，也使得轉換效率有所提升。另一方面，為了要研究微結構對於太陽電池的影響。首先探討微結構的光學和表面特性。接著，利用微結構製作的異質接面太陽電池，其在光電流表現上有著顯著的提升，進而提升轉換效率。再者，藉由提升氧化銦錫透明導電層的成長溫度，太陽電池的填充因子也有所提升。最後探討背表面電場對於異質太陽電池的影響。 | zh_TW |
| dc.description.abstract | In the past few years, the anti-reflection structure was largely used in photovoltaic devices to enhance the light extraction. In order to improve the solar cell conversion efficiency, the anti-reflection structure is studied. The heterojunction solar cell without anti-reflection structure is fabricated for comparison. Besides, inserting intrinsic layer is a way to improve efficiency. The (p) a-Si/ (n) c-Si interface is passivated to reduce leakage current. On the other hand, the properties of textured structure are investigated including optical reflectance and surface morphology. The anti-reflection effect of textured structure is significant. By means of anti-reflection structure, the short circuit current density (Jsc) can be largely enhanced and the efficiency is improved. Next, the improvement of fill factor is facilitated by increasing the deposition temperature of indium tin oxide (ITO). Finally, the effect of back surface field (BSF) structure is studied on solar cell with anti-reflection structure. | en |
