Abstract:	光捕捉與光萃取技術是近年來應用於光電元件效能提升的發展方向之一，其達成的關鍵主要是藉由結合光學理論與半導體相關製程技術。本文內容包含光捕捉與光萃取技術原理及其量測方法以及應用於光電元件之多項製作技術等介紹。提升光電元件的效能不能僅僅單就改善材料品質或是改良元件結構的方面來考量，光電元件本身的光學特性更需要被深入研究，現階段光電元件的發展必須兼顧內部與外部量子效率之提升，而光捕捉和光萃取技術可以分別在應用於太陽電池或發光二極體等元件上，藉此達到入光或出光之外部量子效率增加，進而提升元件整體性能。 Development of optoelectronic devices has attracted a great attention in recent years due to strong interest in renewable energy and the problem of global climate changes. We review the light extraction and light trapping techniques needed for their development. Continuing improvement of the material quality and device structure is critical for the device performance. On the other hand, the enhancement of the light extraction effi ciency of light-emitting diodes and the improvement of the light trapping effi ciency of solar cells are also critical issues. To reduce the problem of refl ectivity for solar cells, several schemes/architectures have been employed to enhance the light trapping. To reduce the problem of light trapping in the high index semiconductor for light emitting diodes,several schemes/architectures have been employed to enhance the light extraction. These include the incorporation of photonic crystals and surface roughening or textured semiconductor surface.
