    Abstract: 因全球暖化和能源危機對再生能源的需求,太陽能成為乾淨能源的發展重點。然而,太陽光譜具有寬波段特性,對於種類不同之太陽能電池其主要光電轉換波段也不同,故發展太陽光分光技術有助於太陽光能利用之最佳化。
    ;In this research, polyimide is the substrate of the spectrum splitter because of its thermal stability, while the designed grating on the substrate is for splitting sun light. To realize the pattern of the grating, optical lithography has been used. Then, the fabricated spectrum splitter has been measured by using a solar simulator, and the measured results have been compared with those from simulation.
    The experiment results have shown that polyimide has the transmittance of 94% and is appropriate for optical applications. The diffraction efficiency of the spectrum splitter has been measured by multiple laser beams with the values of 69% at 405nm, 46% at 635nm, and 36% at 830nm, agreeing with the trend predicted in simulation. Also, according to the thermal experiment, the fabricated spectrum splitter is stable below 300 ℃. Thus, this spectrum splitter is suitable for outdoor usages.
