本文之研究目的在於利用一種新式的抗反射層來改善太陽電池的轉換效率,它是利用一種新的粗糙化結構來降低元件表面的反射率。本方法是利用非晶矽作為犧牲層,並搭配濕式蝕刻來形成抗反射結構。我們可以在晶圓的晶粒內,發現許多細微的孔洞結構。此種新法不只可以改善太陽電池的外部量子效率達90%以上,也可以大幅改善其入射光的反射率。
The purpose of this research is to improve the conversion efficiency of a solar cell by using a new antireflection layer. It is expected that the reflectance can be reduced through of a new textured structure. This method integrates a sacrificial amorphous silicon layer with a wet etching process on silicon wafer to form the antireflected structure. There are many fine etched porous structures distributed in the interior of silicon grain. This new texture structure can not only improve the external quantum efficiency of mono-crystalline silicon solar cell by more than 90%, but also alleviate the reflectance of incident light remarkably.
