摘要

在本論文中，我們研究太陽能集光器的設計，使接受器和集光器配合在效能的運用上可以提升，且模擬太陽入射光只考慮單一波長550nm和太陽光擴散角度0.265度。

在模型的設計上主要分析兩種，第一種是漏斗型集光器，在形狀上固定接受器的面積同時考慮不同高度時上面積相同，同高度時上面積不同，分別在傾斜角為30、45、60度做討論，找到較佳的傾斜角，再去比較漏斗型集光器內部材質-聚甲基丙烯酸甲酯(PMMA)和空氣(AIR)材質，對接受器光通量的影響。

第二種是透鏡型集光器，在形狀上用設計的不同透鏡形狀如圓形、正方形、正方形和正六角形陣列- x方向5個,y方向9個共45個、 正六角形和圓形柱狀，在接受器都是1mm2 面積大小，然後去比較集光比的關系。

本文結果顯示第一種是漏斗型集光器，可以改變漏斗型集光器內部材質來提升光通量; 第二種是透鏡型集光器，改變透鏡的放大的比例可提升集光比，且隨著太陽入射角度增加，集光比會下降。

In this thesis, we focus on the design of solar concentrator to make the detector and solar concentrator utilize more efficiently, and simulate solar incoming light to consider single wave 550um and solar diffusible light 0.265 degree.

From the model design point of view, we primarily want to analysis two kinds of concentrators. The first one is the funnel type of concentrator. We fix the area of receiver on the shape and consider the difference between different height at same area or different area at same height simultaneously. After that, we start to discuss the effects under different degree of inclination like 30, 45 and 60 and try to find better leaning degree of inclination and then we can compare the difference of light flux between Polymethy lmethacrylate (PMMA) and air material inside the funnel type.

The second one is lens type of concentrator. Based on shapes, we use different types of lens made such as circles, squares, square, regular hexahedron arrays, regular hexahedron and cylinder.

As for the square and regular hexahedron arrays, there are five items in x direction and nine items in y direction which are forty five items at whole. And for regular hexahedron and cylinder, they are same detector area which is 1mm2.After that, we can start to find and compare the relationship of concentrator ratio.

Based on results, we can know the first funnel type of concentrator can change material inside the funnel type to promote light flux. The second lens type of concentrator can change enlargement of scale to promote concentrator ratio and make concentrator ratio decrease by increasing solar light angle.
