本論文的目的在於提出一種新的太陽能分光方式，其特殊之處在於本研究利用色差進行分光。所有太陽光頻譜會被分離成兩個部分:可見光頻譜，介於380nm到780nm以及紅外光頻譜，介於780nm~2500nm。 在本分光系統，可見光會被分離並且全內反射至分光導波元件的左右側面，至於紅外光則因為色差直接穿透到分光元件底部。在分光元件底部建有特殊微結構以進行分光。被分離的可見光可以用在太陽能照明系統或矽太陽能電池，而被分離的紅外光可以用在熱電產生裝置或鍺(Ge)太陽能電池。藉此對所有頻譜的太陽光能量都盡可能進行利用和轉換。目前系統的實際總分光比率約為31.9%左右。 ;This paper aims to present a new solution to split solar spectrum. The special point is that this research uses chromatic dispersion to split solar spectrum. The total solar spectrum is divided into two parts: visible part and infrared part. Visible part of solar spectrum is between 380 and 780nm. Infrared part of solar spectrum is between 780nm and 2500nm. In this system, visible part of solar spectrum is directed to left and right side of the waveguide by total internal reflection while infrared part of solar spectrum directly passes through the waveguide. There are special microstructures on the bottom surface of the waveguide, which make this design possible to split solar spectrum. Visible light can be utilized in solar lighting system or silicon solar cells and infrared light can be utilized in thermoelectric devices or Ge(germanium) solar cells. As a result, all spectrum of sunlight can be transformed into useful energy as much as possible. Now the total practical efficiency of this system is about 31.9%.
