摘要:	本論文探討利用非光線追跡設計太陽能電池集光器，本設計包含楔形棱鏡、繞射光柵、與體積小等。利用模擬演算法證明此實驗結果與給出此條件與參考數據。模擬發現此設計太陽能電池集光器，波長可接收範圍在500 nm以上。太陽能集光器的長度與厚度的比例可以超過7，輸入單位面積強度與輸出單位面積強度比值超過3.7，二維的角度容忍度可達到 ±53 °和±13 °。 This thesis explores non-tracking thin profile solar concentrator designs that comprised of a wedge prism and diffractive gratings and their geometrical limitations. Full explanation of the simulation algorithm used to simulate the results in this thesis is also given. The simulation result of the last design shows that a concentrated broad solar spectrum of up to 500 nm can be achieved by utilizing two diffractive gratings. One blazed transmission grating located on the top and another blazed reflection grating placed below bottom surfaces of the wedge prism. The gratings diffract the incident light guiding it into the wedge prism. The guided light is then projected onto the solar module located at the end face of the prism. With this coupling mechanism, the concentrator’s length-to-thickness ratio can exceed 7, the maximum concentration ratio exceeds 3.7, and angular tolerance can reach ±53° and ±9° in the two planes of incidence. In addition, the polarization dependence, as a property of the one-dimensional diffractive grating, is suppressed.
