摘要

隨著能源議題逐漸被受重視，太陽能電池的發展也日趨重要。結晶矽由於其非直接能隙，且能帶工程也很困難，導致較差光伏特，光響應效應。這些因素推遲了使用地球最豐富，最容易取得矽材料來發展第三代、高效率矽基太陽能電池。本文將介紹新項新矽基奈米薄膜技術用於進一步的提升太陽能電池轉換效率，這些包括超低折射率奈米孔洞矽氧薄膜於抗反射層改良、矽量子點超晶格於太陽能電池上的使用、高密度電漿薄膜與晶片混合式太陽能電池，具含矽量子點窗口薄膜層之異質接面結構，與使用電漿／熱線式化學式氣相沉積成長高品質多晶矽於矽薄膜式太陽能電池應用。

As the energy issues attract increasing attentions, the development of solar cells becomes gradually important. Crystalline silicon exhibits indirect band-gap and its band-gap engineering is certainly difficult so that it reveals poor photovoltaic effect and photo-response. As a result, the use of the most abundant and most easily accessible material, silicon, in third-generation high-efficiency Si-based solar cells was constrained. This article will introduce several new silicon-based thin film nanotechnologies so as to enhance conversion efficiency of solar cells to a certain extent. These proposed approaches include the introduction of ultra-low refractive index material, mesoporous silica thin film, in efficient anti-reflective structure, the application of Si quantum dot superlattices in the solar cells, high-density plasma grown thin-films in Si crystalline solar cells, the heterojunction solar cells with Si quantum-dot-embedded window layers, and plasma/hot-wire chemical-vapor-deposition in the growth of high-quality poly-silicon for thin film silicon solar cell applications.
